A normal healthy head of hair has
approximately 100,000 hairs growing. Normal hair follows the continuously
repeating cycle of growth: shedding, resting and regrowth. Since all of these three phases are happening at the same time, three strands of hair in the same
area of your head might each be in at different growth phase. At any given time 85 to 90 percent of your hair is in the first of these phases, actively growing. The remaining 10 to 15% is transitioning or resting in the other two phases. If a follicle is destroyed for any reason no new hair will grow from it. By far the most common cause of hair loss is genetics. By age 50 nearly 50% of men have lost enough hair for it to be noticeable. It occurs due to a hormone called dihydrotestosterone or commonly known as DHT. DHT causes a shortening of the lifespan of the hair follicles in these men. DHT chokes the hair follicle
and it eventually shuts down. Hair loss for women is generally more traumatic than it is for men. The psychological effects can be devastating. There are many different causes of hair loss among women. Most commonly it’s genetically
determined and can be somewhat diffuse in character. Hair loss and women is also quite common in the postpartum period and during menopause. Some hair loss and women is caused by styling such as chemical relaxers, perms and tight braiding.
