General debility, caused by severe or long standing illnesses like typhoid, syphilis, chronic cold, influenza and anaemia, also gives rise to hair disorders. It makes the roots of the hair weak, resulting in falling of hair. An unclean condition of the scalp can also cause loss of hair. This weakens the hair roots by blocking the pores with the collected dirt. Heredity is another predisposing factor which may cause hair to fall. Scalp reduction is performed on patients with well-defined bald spots in the crown area of the scalp. It is sometimes done in conjunction with hair transplantaion to reduce the size of the bald scalp, especially in patients who do not have enough donor hair to cover the bald areas. Silicon bags are inserted beneath an area of hairy scalp and gradually inflated with saline water over a six-week period. This causes the hair-bearing skin to stretch, thus increasing the amount of hair-bearing scalp. After removing the bags, expanded hair bearing skin is lifted and moved to an adjacent bald area where a similar sized patch of scalp has been excised. 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. New hair resulting from minoxidil use may be thinner and shorter than previous hair. But there can be enough regrowth for some people to hide their bald spots and have it blend with existing hair. New hair stops growing soon after you discontinue the use of minoxidil. If you experience minimal results within six months, your doctor may recommend discontinuing use. Side effects can include irritation of the scalp. Finasteride (Propecia). This prescription medication to treat male-pattern baldness is taken daily in pill form. Many people taking finasteride experience a slowing of hair loss, and some may show some new hair growth. Positive results may take several months. Finasteride works by inhibiting the conversion of testosterone into dihydrotestosterone (DHT), a hormone that shrinks hair follicles and is an important factor in male hair loss. Rare side effects of finasteride include diminished sex drive and sexual function. As with minoxidil, the benefits of finasteride stop if you stop using it. 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. Anthralin (Drithocreme). Available as either a cream or an ointment, anthralin is a synthetic, tarry substance that you apply to your scalp and wash off daily. It's typically used to treat psoriasis, but doctors can prescribe it to treat other skin conditions. Anthralin may stimulate new hair growth for cases of alopecia areata.
It is good to shampoo your hair--we recommend at least three times a week. This helps to remove dirt and buildup on the hair that can deteriorate the condition of your scalp. When shampooing, it is very important that you pay attention to cleansing your hair, your scalp and your hair line. 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. 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 requires the same overall nutrition that the body does: plenty of fresh fruits and vegetables, grains and protein including lean meat and fish. Dietitians recommend foods high in biotin, including brown rice, bulgar, brewer's yeast, soybeans, green peas, lentils, oats, sunflower, seeds and nutritious nuts.
The outer layer is called the cuticle and is thin and colorless, its job is to protect the thicker cortex which contains the melanin. Melanin is responsible for the color of your hair and the actual color depends on what kind of melanin you have . 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. 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.

Hair transplantation
- Hair transplantation is a surgical procedure used to treat baldness or hair loss (alopecia). Typically, tiny patches of scalp are removed from the back and sides of the head and implanted in the bald spots in the front and top of the head.
Protein
- Important building blocks of the body, composed of amino acids, involved in the formation of body structures and controlling the basic functions of the human body.
- Complex organic molecules made up of amino acids. Proteins are basic components of all living cells and are therefore among the principal substances that make up the body.
Ringworm
- The term "ringworm" refers to fungal infections that are on the surface of the skin. The early belief was that the infection was due to a worm, which it is not, although the name has stuck. Some of these fungi produce round spots, but many do not.
Thyroid

- A large gland in the neck that functions in the endocrine system. The thyroid secretes hormones that regulate growth and metabolism.
