Hair care and hair loss

Hair growAnother 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. 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. There are many surgical procedures which will help to restore the hair from falling. Surgical restoration is the only permanent solution to baldness. It involves a series of operations that extract plugs of scalp from the sides and back of your head, where hair grows densely, and implant them on top and in front, where you are going bald. For men, hair loss is male pattern baldness. Yes, there are other types of hair loss, including rare conditions such as alopecia totalis and alopecia universalis, where the entire scalp and entire body, respectively, become completely bald due to a viral condition that is irreversible. There is also patch baldness, in which hair falls out in patches of the scalp. This is caused by stress or poor nutrition or adverse scalp conditions. But the hair will usually grow back once the cause has been rectified. The effectiveness of medications used to treat alopecia depends on the cause of hair loss, extent of the loss and individual response. Generally, treatment is less effective for more extensive cases of hair loss. 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. 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. Hair care advisesMany people (wrongly) will drop a handful of shampoo on their head and then rinse it off. Shampoo must be worked through all of your hair, as well as the scalp and hairline. Did you notice that when you shampoo your hair the amount of lather often varies? Usually, the more lather you have, the less buildup you have on your hair. It's also important to fully rinse out the shampoo to eliminate any residual detergents--they can damage the hair shaft and scalp. 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. How does hair grow?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 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 transplantationHair transplantation has come a long way from the days of "hair plugs" and a pleasing, natural result is now routine. It is an excellent option for treatment of hereditary hair loss in many men and women. Hair transplantation is done under local anesthesia as an outpatient procedure. Hair and follicles are removed from the "donor area" of permanent hair along the back and sides of the head. This area is immediately camouflaged by the surrounding hair. Since hair transplantation is a surgical procedure, all patients must be in good health. Hair transplantation is an office procedure that takes approximately four to eight hours depending on the extent of the planned procedure. Most people return to work two to five days after the surgery. Most people require more than one session, each spaced at least six months apart each to complete the hair restoration in an area. The timing and number of transplants depends on the amount of hair you have when you start, how much is anticipated that you will continue to lose without transplanting and how much hair density you desire. In most cases, immediately after the hair transplant the hairs fall out of the grafts, and do not regrow for 1-3 months. After this they begin to grow as normal hair. With each session there is more hair, and the resulting appearance is thicker hair. Hair transplantation can be done both on patients with advanced baldness and earlier thinning. Newer treatments for men like Propecia or for both men and women, like Rogaine should be considered as well especially in patients with earlier thinning as these medications often slow significantly the progression of hair loss. In general, hair transplantation is not considered for patients younger than their mid 20s because of difficulty in predicting ultimate extent of hair loss. Almost worse than hair loss in some cases is hair miniaturization-the fine-caliber, wispy hair that grows out a follicle when the follicle is no longer able to produce hair of normal size. Miniaturized hair is hard to style and difficult to conceal. It begins to appear in the course of female pattern hair loss, the female form of the most common type of hair loss in men. Hair loss is not "an inevitable sign of getting older". It has been reported in studies that about 80% of women experience some degree of hair loss before menopause. Much of this hair loss has a hereditary basis-female pattern hair loss. A woman who has a family history of hair loss in women may be especially aware of the possibility that she may also begin to lose hair as she matures. And, she would be correct; a family history of hair loss in women is an indication that a woman may be genetically predisposed to lose hair.
