Coconut Oil for Hair

Coconut oil is very popular and very preferred as hair oil worldwide. Let us find out why.




Since their childhood, people living in most of the coastal areas of the world, more specifically in the areas where coconut grows in abundance, such as in the Indian Subcontinent, Sri Lanka, Indonesia, Malaysia, Burma, Philippines etc., know the one and the only, the sweet smelling coconut oil as their only hair oil. Coconut oil has been in use as hair oil for ages and it has shown remarkable results. Certain components in it keep the hair strong, vitalized, nourished and protected from effects of ageing. Let us see those components and their effects on hair.



•Lauric Acid: One of the most responsible reasons behind hair fall and hair loss is microbial action on the scalp and hair roots. So, to protect hair against them, what we need is an antimicrobial agent. Lauric Acid present in Coconut Oil is one of them. It is basically a triglyceride which yields a monoglyceride called Monolaurin when acted upon by a species of bacteria which breaks the glycerol bonds. This monolaurin has excellent antimicrobial properties.

•Capric Acid: This is yet another triglyceride present in Coconut oil, which, like Lauric Acid, yields another monoglyceride called Monocaprin due to bacterial action, having antimicrobial properties similar to that of monolaurin.

•Vitamin-E: Almost every aptly educated person knows the importance of vitamin-E for skin and hair. It keeps scalp and skin healthy and hair rejuvenated.

•Moisture Retaining Capacity: Coconut Oil has high moisture retaining capacity, since it is not broken down easily nor evaporated, being very stable. It does not let moisture escape thus keeping hair moistened and soft. This prevents breakage of hair. Coconut Oil is a far better conditioner for hair than any synthetic one available in the market.

•Anti-Dandruff: The various fatty acids present in Coconut Oil serve as very good anti dandruff agents and are way better than any anti dandruff shampoo. A regular application can help you get rid of dandruffs for ever.

•Styling: Coconut oil can be good styling oil for hair too, as it melts on heating and then condenses on cooling. So when you apply it on your hair, it thins and spreads evenly due to heat of the scalp. Soon afterwards, as the hair comes in contact with air, the oil on hair condenses on cooling and thus works as a styling gel or cream.

If you ever visit coastal parts of India, like West Bengal, Kerala, Coastal Tamil Nadu etc, you will be surprised to see lots and lots of old men and women, in their 70s and 80s, still having thick jet black hair. Thanks to the coastal climate, the rice and fish meal and of course, to the pure coconut oil they use on hair.

Health Benefits of Coconut Oil

The health benefits of coconut oil include hair care, skin care, stress relief, maintaining cholesterol levels, weight loss, increased immunity, proper digestion and metabolism, relief from kidney problems, heart diseases, high blood pressure, diabetes, HIV and cancer, dental care, and bone strength. These benefits of coconut oil can be attributed to the presence of lauric acid, capric acid and caprylic acid, and its properties such as antimicrobial, antioxidant, antifungal, antibacterial, soothing, etc.
The human body converts lauric acid into monolaurin which is claimed to help in dealing with viruses and bacteria causing diseases such as herpes, influenza, cytomegalovirus, and even HIV. It helps in fighting harmful bacteria such as listeria monocytogenes and heliobacter pylori, and harmful protozoa such as giardia lamblia. As a result of these various health benefits of coconut oil, though its exact mechanism of action was unknown, it has been extensively used in Ayurveda, the traditional Indian medicinal system.

Coconut oil is often preferred by athletes and body builders and by those who are dieting. The reason behind this being that coconut oil contains lesser calories than other oils, its fat content is easily converted into energy and it does not lead to accumulation of fat in the heart and arteries. Coconut oil helps in boosting energy and endurance, and enhances the performance of athletes.

Composition: Coconut oil consists of more than ninety percent of saturated fats (Don’t panic! First read to the last word. Your opinion may change), with traces of few unsaturated fatty acids, such as monounsaturated fatty acids and polyunsaturated fatty acids. Virgin Coconut Oil is no different from this. Let us have a bit detailed study of this.

• The Saturated Fatty Acids: Most of them are Medium Chain Triglycerides, which are supposed to assimilate well. Lauric Acid is the chief contributor, with more than forty percent of the share, followed by Capric Acid, Caprylic Acid, Myristic Acid and Palmitic.
• The Polyunsaturated Fatty Acids: Linoleic Acid.
• The Monounsaturated Fatty Acids: Oleic Acid.
• The Poly-phenols: Gallic Acid, which is phenolic acid. These poly-phenols are supposed to be responsible for the fragrance and the taste of Coconut Oil and Virgin Coconut Oil is rich in these poly-phenols.
• Certain derivatives of fatty acid like Betaines, Ethanolamide, Ethoxylates, Fatty Esters, Fatty Polysorbates, Monoglycerides and Polyol Esters.
• Fatty Chlorides, Fatty Alcohol Sulphate and Fatty Alcohol Ether Sulphate, all of which are derivatives of Fatty Alcohols.
• Vitamins (predominantly Vitamin-E) and minerals.
• A bit of moisture.
  
  Health benefits of coconut oil include the following:

• Hair Care: Coconut oil is one of the best natural nutrition for hair. It helps in healthy growth of hair providing them a shinny complexion. Regular massage of the head with coconut oil ensures that your scalp is free of dandruff, lice, and lice eggs, even if your scalp is dry. Coconut oil is extensively used in the Indian sub-continent for hair care. It is an excellent conditioner and helps in the re-growth of damaged hair. It also provides the essential proteins required for nourishing damaged hair. It is therefore used as hair care oil and used in manufacturing various conditioners, and dandruff relief creams. Coconut oil is normally applied topically for hair care.
• Stress Relief: Coconut oil is very soothing and hence it helps in removing stress. Applying coconut oil to the head followed with a gentle massage helps in removing mental fatigue.
• Skin Care: Coconut oil is excellent massage oil for the skin as well. It acts as an effective moisturizer on all types of skins including dry skin. The benefit of coconut oil on the skin is comparable to that of mineral oil. Further, unlike mineral oil, there is no chance of having any adverse side effects on the skin with the application of coconut oil. Coconut oil therefore is a safe solution for preventing dryness and flaking of skin. It also delays wrinkles, and sagging of skin which normally become prominent with age. Coconut oil also helps in treating various skin problems including psoriasis, dermatitis, eczema and otherskin infections. Therefore coconut oil forms the basic ingredient of various body care products such as soaps, lotions, creams, etc., used for skin care.
• Premature Aging: Coconut oil helps in preventing premature aging and degenerative diseases due to its antioxidant properties.
• Heart Diseases: There is a misconception spread among many people that coconut oil is not good for the heart. This is because it contains a large quantity of saturated fats. However, coconut oil is beneficial for the heart. It contains about 50% lauric acid, which helps in preventing various heart problems including high cholesterol levels and high blood pressure. The saturated fats present in coconut oil are not harmful as it happens in case of other vegetables oils. It does not lead to increase in LDL levels. It also reduces the incidence of injury in arteries and therefore helps in preventing atherosclerosis.
• Weight Loss: Coconut oil is very useful in reducing weight. It contains short and medium-chain fatty acids that help in taking off excessive weight. It is also easy to digest and it helps in healthy functioning of the thyroid and enzymes systems. Further, it increases the body metabolism by removing stress on pancreases, thereby burning out more energy and helping obese and overweight people reduce their weight. Hence, people living in tropical coastal areas, who eat coconut oil daily as their primary cooking oil, are normally not fat, obese or overweight.
• Pancreatitis: Coconut oil is also believed to be useful in treating pancreatitis.
• Digestion: Internal use of coconut oil occurs primarily as cooking oil. Coconut oil helps in improving the digestive system and thus prevents various stomach and digestion related problems including irritable bowel syndrome. The saturated fats present in coconut oil have anti microbial properties and help in dealing with various bacteria, fungi, parasites, etc., that cause indigestion. Coconut oil also helps in absorption of other nutrients such as vitamins, minerals and amino acids.
• Immunity: Coconut oil is also good for the immune system. It strengthens the immune system as it contains antimicrobial lipids, lauric acid, capric acid and caprylic acid which have antifungal, antibacterial and antiviral properties. The human body converts lauric acid into monolaurin which is claimed to help in dealing with viruses and bacteria causing diseases such as herpes, influenza, cytomegalovirus, and even HIV. It helps in fighting harmful bacteria such as listeria monocytogenes and heliobacter pylori, and harmful protozoa such as giardia lamblia.
• Healing: When applied on infections, it forms a chemical layer which protects the infected body part from external dust, air, fungi, bacteria and virus. Coconut oil is most effective on bruises as it speeds up the healing process by repairing damaged tissues.
• Infections: Coconut oil is very effective against a variety of infections due to its antifungal, antiviral, and antibacterial properties. According to the Coconut Research Center, coconut oil kills viruses that cause influenza, measles, hepatitis, herpes, SARS, etc. It also kills bacteria that cause ulcers, throat infections, urinary tract infections, pneumonia, and gonorrhea, etc. Coconut oil is also effective on fungi and yeast that cause candidiasis, ringworm, athlete's foot, thrush,diaper rash, etc.
• Liver: The presence of medium chain triglycerides and fatty acids helps in preventing liver diseases as they substances are easily converted into energy when they reach the liver, thus reducing work load on the liver and also preventing accumulation of fat.
• Kidney: Coconut oil helps in preventing kidney and gall bladder diseases. It also helps in dissolving kidney stones.
• Diabetes: Coconut oil helps in controlling blood sugar, and improves the secretion of insulin. It also helps in effective utilization of blood glucose, thereby preventing and treating diabetes.
• Bones: As mentioned earlier, coconut oil improves the ability of our body to absorb important minerals. These includecalcium and magnesium which are necessary for development of bones. Thus coconut oil is very useful to women who are prone to osteoporosis after middle age.
• Dental Care: Calcium is an important element present in teeth. Since coconut oil facilitates absorption of calcium by the body, it helps in getting strong teeth. Coconut oil also stops tooth decay.
• HIV and Cancer: It is believed that coconut oil plays an instrumental role in reducing viral susceptibility of HIV and cancerpatients.

Health effect of Coconut Oil

Health effects debate
Historically, many populations within the tropics have used coconut medicinally as a treatment for a wide variety of ailments.
A study into the effects of a "diet rich in.." medium-chain fatty acids (such as in coconut oil and butter), concluded that "MCFAs in the form of MCTs significantly increased plasma triacylglycerol and LDL-cholesterol concentrations and the ratio of LDL to HDL cholesterol and thereby resulted in a less beneficial lipid profile overall."
However, research done by nutritionist Mary Enig has found that non-hydrogenated coconut oil (ie. extra-virgin) consumed in moderate amounts "is at worst neutral with respect to atherogenicity of fats and oils and, in fact, is likely to be a beneficial oil for prevention and treatment of some heart disease."

Food Uses
Cooking
Coconut oil is commonly used in cooking, especially when frying. In communities where coconut oil is widely used in cooking, the unrefined oil is the one most commonly used. Coconut oil is commonly used to flavor many South Asian curries.
Hydrogenated or partially-hydrogenated coconut oil is often used in non-dairy creamers, and snack foods.

Cosmetics and skin treatments
Coconut oil is excellent as a skin moisturizer and softener. A study shows that extra virgin coconut oil is effective and safe when used as a moisturizer, with absence of adverse reactions.
Fractionated coconut oil is also used in the manufacture of essences, massage oils and cosmetics.
In India and Sri Lanka, coconut oil is commonly used for styling hair, and cooling or soothing the head.

Soaps and detergents
Coconut oil is used as a base oils for soap, shampoo and detergent making.

Traditional use
Coconut oil is used in oil lamps.

In diesel engines
Coconut oil has been tested for use as a feedstock for biodiesel to be used as a diesel engine fuel. In this manner it can be applied to power generators and transport using diesel engines. Since straight coconut oil has a high gelling temperature (22-25°C), a high viscosity, and a minimum combustion chamber temperature of 500 °C (932 °F) (to avoid polymerization of the fuel), coconut oil is typically transesterified to make biodiesel. Use of B100 (100% biodiesel) is only possible in temperate climates as the gel point is approximately 10°C (50 degrees Fahrenheit). The oil needs to meet the Weihenstephan standard for pure vegetable oil used as a fuel otherwise moderate to severe damage from carbonisation and clogging will occur in an unmodified engine.
The Philippines, Vanuatu, Samoa, and several other tropical island countries are using coconut oil as an alternative fuel source to run automobiles, trucks, and buses, and to power generators. Coconut oil is currently used as a fuel for transport in the Philippines. Further research into the oil's potential as a fuel for electricity generation is being carried out in the islands of the Pacific. In the 1990s Bougainville conflict, islanders cut off from supplies due to a blockade used it to fuel their vehicles.

Engine lubricant
Coconut oil has been tested for use as an engine lubricant; the producer claims the oil reduces fuel consumption, smoke emissions and allows the engine to run at a cooler temperature.

Transformer oil
Transformer oil acts as an insulating and cooling medium in transformers. The insulating oil fills up pores in fibrous insulation and also the gaps between the coil conductors and the spacing between the siding and the tank, and thus increases the dielectric strength of the insulation. A transformer in operation generates heat in the winding, and that heat is transferred to the oil. Heated oil then flows to the radiators by convection. Oil supplied from the radiators, being cooler, cools the winding. There are several important properties such as dielectric strength, flash point, viscosity, specific gravity and pour point and all of them have to be considered when qualifying an oil for use in transformers. Normally mineral oil is used, but coconut oil has been shown to possess all the properties needed to function as an environmentally friendly and economic replacement to mineral oil for this purpose.

Introduction to Coconut Oil

Coconut oil is extracted from the kernel or meat of matured coconut harvested from the coconut palm (Cocos nucifera). Throughout the tropical world it has provided the primary source of fat in the diets of millions of people for generations. It has various applications in food, medicine, and industry. What makes coconut oil different from most other dietary oils is the basic building blocks or fatty acids making up the oil. Coconut oil is composed predominately of a special group of fat molecules known as medium chain fatty acids (MCFA). The majority of fats in the human diet are composed almost entirely of long chain fatty acids (LCFA).
The primary difference between MCFA and LCFA is the size of the molecule, or more precisely, the length of the carbon chain that makes up the backbone of the fatty acid. MCFA have a chain length of 6 to 12 carbons. LCFA contain 14 or more carbons.
The length of the carbon chain influences many of the oil’s physical and chemical properties. When consumed, the body processes and metabolizes each fatty acid differently depending on the size of the carbon chain. Therefore, the physiological effects of the MCFA in coconut are significantly different from those of the LCFA that are more commonly found in the diet.
MCFA and LCFA can also be classified as saturated, monounsaturated, or polyunsaturated fatty acids. Coconut oil contains 92% saturated fatty acids. All of the MCFA in coconut oil are saturated. They, however, are very much different chemically from the long chain saturated fatty acids found in animal fat and other vegetable oils.
Because coconut oil has a high amount of saturated fatty acids it also has a relatively high melting point. Above 76°F (24°C) coconut oil is a colorless liquid. Below this temperature it solidifies into a pure white solid.
Coconut oil is very heat stable so it makes an excellent cooking and frying oil. It has a smoke point of about 360°F (180°C). Because of its stability it is slow to oxidize and thus resistant to rancidity, lasting up to two years due to high saturated fat content.

Types of oil available
Virgin coconut oil
Virgin coconut oil is produced from fresh coconuts (rather than dried, as in copra) with minimal processing so that it retains a slight coconut flavor and aroma. Virgin coconut oil is regarded as the highest quality coconut oil and is preferred for food preparation and home medicinal use.
There are several ways to produce virgin coconut oil, each of which can be processed under two general methods: wet process or dry process.
In the wet process, coconut milk is made first and then the oil is extracted from the milk. Coconut kernel is shredded, mixed with a little water, and then squeezed or pressed to extract the oil. The resulting oil/water mixture produces coconut cream or coconut milk depending on the percentage of oil. The coconut milk is then allowed to separate naturally. Since oil is lighter than water, the oil rises to the surface. This takes 12 to 24 hours. The oil can then be skimmed off. This is the traditional method of making coconut oil from coconut milk and is the way many people make the oil at home. Other methods incorporate heating, fermentation, refrigeration, or centrifugal force to separate the oil from the water. Some minor heating is generally done afterwards (often in a low temperature vacuum chamber) to drive off excess moisture and produce a more purified product and to extend shelf life.
In the dry process the oil is extracted directly from the kernel. The coconut kernel is first shredded and dried in an oven to about 10 to 12% moisture. The dried, shredded coconut is then placed into a press and the virgin oil is expelled.
The Asian and Pacific Coconut Community (APCC), whose 18 members produce about 85% of the coconut sold commercially, has published its Standards for Virgin Coconut Oil. The Philippines has established a Department of Science and Technology (DOST) governmental standard.

RBD coconut oil
Coconut Oil expelled from Copra at an oil mill in Tripunithura, Kerala, IndiaRBD stands for “refined, bleached, and deodorized.” RBD oil is usually made from copra (dried coconut kernel). Copra can be made by smoke drying, sun drying, or kiln drying. The dried copra is then placed in a powerful hydraulic press with added heat and the oil is extracted. This yields up practically all the oil present, amounting to more than 60% of the dry weight of the coconut.
This “crude” coconut oil is not suitable for consumption because it contains contaminants and must be refined with further heating and filtering. Another method for extraction of a “high quality” coconut oil involves thenzymatic action of alpha-amylase, polygalacturonases and proteases on diluted coconut paste.
Unlike virgin coconut oil, refined coconut oil has no coconut taste or aroma. RBD oil is used for home cooking, commercial food processing, and cosmetic, industrial, and pharmaceutical purposes.

Hydrogenated coconut oil
RBD coconut oil can be processed further into partially or fully hydrogenated oil to increase its melting point. Since virgin and RBD coconut oils melt at 76°F (24°C) foods, such as chocolate, tend to melt in warm climates. A higher melting point is desirable in these warm climates so the oil is hydrogenated. The melting point of hydrogenated coconut oil is 97-104°F (36-40°C).
In the process of hydrogenation, unsaturated fats (monounsaturated and polyunsaturated fatty acids) are bombarded with hydrogen atoms to make them more saturated. Coconut oil contains only 6% monounsaturated and 2% polyunsaturated fatty acids. In this process some of these are transformed into trans fatty acids.

Fractionated coconut oil
Fractionated coconut oil is a fraction of the whole oil, in which the long-chain fatty acids are removed so that only medium chain saturated fatty acids remain. Lauric acid, a 12 carbon chain fatty acid, is often removed as well because of its high value for industrial and medical purposes. Fractionated coconut oil may also be referred to as caprylic/capric triglyceride oil or medium chain triglyceride (MCT) oil because it is primarily the medium chain caprylic (8 carbons) and capric (10 carbons) acids that make up the bulk of the oil.
MCT oil is most frequently used for medical applications and special diets.
