Hair care and hair loss
The healthy condition of the hair depends, to a very large extent, on the intake of sufficient amounts of essential nutrients in the daily diet. Hair is made of keratin, a protein, which also makes up the nails and the outer layer of our skin. Another factor that has been linked to hair loss is the amount of sebum in the scalp. Sebum contains a high amount of DHT, and clogs pores in the scalp, both of which cause the malnutrition of the hair root. The amount of sebum in balding hair is related to the amount of oil in the hair. Meanwhile most doctors agree that frequent shampooing is advised in hair loss cases with oily scalps. Another important cause of falling hair is stress, such as worry, anxiety and sudden shock. Stress leads to a severe tension in the skin of the scalp. This adversely affects the supply of essential nutrition required for the healthy growth of hair. Male pattern baldness that is the condition responsible for over 98% of all hair loss in men. It gets its name from the pattern of hair loss, which ultimately results in a horseshoe of hair that resides on the sides and back of the head, while the top of the head is completely bald. Some men begin MPB by losing the hair in their hairline. Others start in the crown. The most familiar hair loss pattern is where the hair begins to recede in the hairline and the crown at roughly the same time. The hair in the mid-scalp or anterior scalp is often the last to go. But go it will, eventually leaving a man with the horseshoe of hair that is the telltale sign of typical male pattern baldness. For women, hair loss is different. There is no set pattern for womens androgenic hair loss, which like MPB, occurs in the overwhelming majority of cases. Women can suffer from alopecia totalis and alopecia universalis just like men. Women can experience patch baldness for the same reasons as men (stress, poor nutrition, etc.), as well as due to hormonal changes from pregnancy and certain eating disorders. However, like men, the hair will generally grow back. Minoxidil (Rogaine). This over-the-counter medication is approved for the treatment of androgenetic alopecia and alopecia areata. Minoxidil is a liquid that you rub into your scalp twice daily to regrow hair and to prevent further loss. Some people experience some hair regrowth or a slower rate of hair loss or both. Minoxidil is available in a 2 percent solution and in a 5 percent solution. Corticosteroids. Injections of cortisone into the scalp can treat alopecia areata. Treatment is usually repeated monthly. Doctors sometimes prescribe corticosteroid pills for extensive hair loss due to alopecia areata. Ointments and creams can also be used, but they may be less effective than injections. Do you feel that you are the only one losing hair? You're not! The most common form of hair loss, Androgentic Alopecia, or pattern baldness, is experiences by 50-80% of Caucasian men. The number of Chinese males affected are half of the Caucasian counterparts while African Americans have a lower incidence of the condition as well. For women androgenetic alopecia occurs between 20-40% of the general female population. In summary, it is safe to say that pattern baldness is experienced by the norm of the population, you're not alone, but actually in the majority. Alopecia Areata - In this type of hair loss, hair usually falls out, resulting in totally smooth, round patches about the size of a coin or larger. It can, rarely, result in complete loss of scalp and body hair. This disease may affect children or adults of any age. The cause of alopecia areata is unknown. Apart from the hair loss, affected persons are generally in excellent health. In most cases, the hair regrows by itself. Dermatologists can treat many people with this condition. Treatments include topical medications, a special kind of light treatment, or in some cases pills. Inadequate Protein in Diet - Some people who go on crash diets that are low in protein, or have severely abnormal eating habits, may develop protein malnutrition. The body will save protein by shifting growing hairs into the resting phase. Massive hair shedding can occur two to three months later. Hair can then be pulled out by the roots fairly easily. This condition can be reversed and prevented by eating the proper amount of protein and, when dieting, maintaining adequate protein intake. Low Serum Iron - Iron deficiency occasionally produces hair loss. Some people don't have enough iron in their diets or may not fully absorb iron. Women who have heavy menstrual periods may develop iron deficiency. Low iron can be detected by laboratory tests and can be corrected by taking iron pills. Major Surgery/Chronic Illness - Anyone who has a major operation may notice increased hair shedding within one to three months afterwards. The condition reverses itself within a few months but people who have a severe chronic illness may shed hair indefinitely. Correct use of conditioners containing light proteins, such as hydrolyzed human hair keratin proteins, can help strengthen your hair. A good conditioner with these proteins can easily penetrate the hair shaft to replenish nutrients. These proteins can also repair split ends. Split ends develop after the protective cuticle has been stripped away from the end of hair fibers as a result of harsh chemicals or even vigorous brushing. Excessive exposure to the sun can damage your hair by inducing oxidation of the sulfur molecules within the hair shaft, leaving the hair weak, brittle, dry and faded. People who bleach or lighten their natural hair color may also notice slight color changes in their hair when it is exposed to sun. Blond hair may turn yellow, fade or become dull due to UV exposure. Even natural brunette hair tends to develop reddish hues from sun exposure due to oxidation of melanin pigments. Hair is composed of Keratin, a special protein that also produces our fingernails and toenails the nails and forms the protective outer layer of our skin. Each strand of hair consists of three concentric layers, the cuticle, the cortex and the medulla. The innermost layer of hair is called the medulla and reflects light giving hair the various color tones it has. That's why hair color looks a lot different in sunlight than it does in the shade. Whether you have straight or curly hair depends on the shape of the cortex. If the cross section of the cortex is round you will have straight hair, if the cortex is oval shaped you will have curly or wavy hair. The physical thickness and length of hair depends on what type of hair it is. Vellus hair is the fine fuzz type of hair that's often called peach fuzz. Its very fine and colorless and often almost invisible to the naked eye.
