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. 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. 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. 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. The chief difference in womens androgenic hair loss from mens (both are hormone related) is that women tend to experience thinning that occurs in no particular pattern or part of the scalp. Unlike men, the scalp may not actually be totally denuded of hair, just thin to the point where the scalp is visible. Like men, however, the resulting hair loss is generally irreversible. Finasteride is not approved for use by women. In fact, it poses significant danger to women of childbearing age. If you're a pregnant woman, don't even handle crushed or broken finasteride tablets because absorption of the drug may cause serious birth defects in male fetuses. 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.
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. 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. Hair that is dark and very visible is known as Terminal hair. Terminal hair is the hair that we refer to when talk about hair. Whether a hair is a fine vellus hair or a thick dark hair depends entirely on the follicle that is producing the hair. In balding men thick terminal hair is often replaced by fine vellus hair. This is a result of the hair producing equipment, the follicle, suffering physical damage and being unable to produce terminal hair. The average Caucasian person has 5 million hairs of which 100,000 - 150,000 are on the head. Blondes not only have more fun, they also have more hair, about 140,000 more than average, Brunettes have slightly higher than average hair about 105,000 hairs, and redheads have a little less than average about 90,000 hairs.
Hair transplantation is a surgical modality used for the correction of androgenic alopecia, scarring alopecia, and other causes of permanent alopecia. 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. The removed hair follicles are then divided into individual grafts of varying sizes. The smallest grafts contain 1-2 hairs and are often referred to as "follicular units" or "micrografts". Larger minigrafts may contain up to 6 hairs and can provide more density per graft. Choice of number and type of graft is made taking into account the patient's hair type, quality, color and the area to be transplanted. Once prepared the grafts (hair and its roots) are then inserted into the thin area. 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. In the hands of well-trained and experienced physicians, and using newer techniques with smaller grafts, the hair grows in the proper direction with a feathered hairline, and a highly aesthetic result. The site from where the hair is taken is usually a fine scar line which is hidden by the permanent hair in that area. After the procedure there are tiny marks where the grafts have been placed. Initially there is some crusting over these areas (5-14 days) but after this, these areas are usually not detectable. Women with localized thinning on the top of their heads or thinning around the temples often make good candidates for hair transplantation. Prior to evaluation for hair transplantation, it is important for women to discuss your thinning hair with a dermatologist and/or endocrinologist to make sure there is no other treatable reason for the 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.
Androgenic alopecia develops when the hair follicle (the place under the skin where hair grows from) experiences a reduction in size, as well as a time reduction in the active growth phase. this translates into a simple fact: more and more of the hair follicles will spend time in the resting state where hair is shed once the state is completed. Fortunately, androgenic alopecia does not develop in all hair follicles at the same time. This is why some part of the scalp seems to be losing more hair than the other. High Fever, Severe Infection, Severe Flu - Illnesses may cause hairs to enter the resting phase. Four weeks to three months after a high fever, severe illness or infection, a person may be shocked to see a lot of hair falling out. This shedding usually corrects itself. Cancer Treatments - Some cancer treatments will cause hair cells to stop dividing. Hairs become thin and break off as they exit the scalp. This occurs one to three weeks after the treatment. Patients can lose up to 90 percent of their scalp hair. The hair will regrow after treatment ends. Patients may want to get wigs before treatment. 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. Hair Pulling (Trichotillomania) - Children and sometimes adults will twist or pull their hair, brows or lashes until they come out. In children especially, this is often just a bad habit that gets better when the harmful effects of that habit are explained. Sometimes hair pulling can be a coping response to unpleasant stresses and occasionally is a sign of a serious problem needing the help of a mental health professional.
