Advanced hair replacement

Alopecia:

Alopecia areata usually begins when clumps of hair fall out, resulting in totally smooth, round hairless patches on the scalp. In some cases
the hair may become thinner without noticeable patches of baldness, or it may grow and break off, leaving short stubs (called "exclamation point" hair). Rarely, complete loss of scalp hair and body hair occurs. The hair loss often comes and goes—hair will grow back over several months in one area but will fall out in another area.

Hormonal:

Since hormones both stimulate hair growth and cause hair loss, hormonal changes by far have the biggest impact on hair loss. These can affect both men and women in the following ways: This is the most common cause of thinning and affects both men and women. Men generally have hair loss concentrated in a specific pattern from the front through to the crown. Women tend to have thinning throughout their head without being in any specific pattern. This type of hair loss is caused by the androgen DHT, or Dihydrotestosterone. Since everyone has DHT that is produced by their bodies and only some people suffer from hair loss there has to be another factor involved. This other factor is having follicles that have a greater number of Androgen receptors for the DHT to attach to. This is the component that is inherited through the genes. To date the most effective preventative treatments are anti androgens, drugs that prevent the creation of DHT. In the future gene therapy will one day be able to alter the genes to prevent the follicles from being affected by DHT. Hair Styling Treatments: Many people change the appearance of their hair by using chemical treatments like dyes, tints, bleaches, straighteners, relaxers and permanent waves. If correctly done and done using reputable products, its rare to have any damage. However, hair can become weak and break if any of these chemicals are used too often. Hair can also break if the solution is left on too long, if two procedures are done on the same day, or if bleach is applied to previously bleached hair. Some chemical relaxers do contain powerful chemicals and there have been instances of people get chemical burns from these products resulting in permanent hair loss.

Major surgery/chronic illness:

Anyone who has a major operation - a tremendous shock to the system - 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. A relatively unknown fact is that hair transplantation surgery can actually cause additional hair loss or "shock fallout". Hairs lost from shock fallout usually don't regrow.

Female Pattern Hair Loss:

As women age, their hair tends to thin out, although the results are not as dramatic as they are for many men - think of your grandmother's hair compared to your grandfather's (if he has any). Women's pattern of hair loss is analogous to men's, but has several important differences. The ages we begin having hair loss are the same. A few of both sexes will begin having hair loss very early--in their twenties, but most do not note changes until the mid-thirties to forties. Women's hair loss tends to be an even overall thinning; as opposed to men's hair loss in which the hairline recedes and/or there is balding at the crown of the head. Women tend to lose hair on the crown and at the hairline, which is referred to as female-pattern hair loss.

Male Pattern Hair Loss:

Most men are genetically predisposed to male pattern baldness. It is the effect of hormones on the hair follicle that produces male pattern baldness. Testosterone, a hormone that is present in high levels in males after puberty, is converted to dihydrotestosterone (DHT) by an enzyme called 5-alpha reductase. DHT has an adverse affect on the hair follicles. Acting on a hormone receptor on the hair follicle it slows down hair production and produces weak, shorter hair, sometimes it stops hair growth from the follicle completely. This process gradually depletes your stock of hair and is normal hair loss.
