The normal hair cycle of hair growth lasts for 2 to 6 years. Each hair grows (approx.) 1 centimeter per month during this phase. About 90 percent of the hair on your scalp is growing at any one time. About 10 percent of the hair on your scalp, at any one time, is in a resting phase. After 2 to 3 months, the resting hair falls out and new hair starts to grow in its place.
It is normal to shed some hair each day as part of this cycle. Hair loss of this type can affect men, women and children.
Male pattern baldness (called also alopecia androgenetica) is the most common form of hair loss in men. Testosterone is involved in male pattern baldness .Testosterone is naturally converted in the body to a related sex hormone, dihydrotestosterone (DHT). This stimulates the growth of facial and body hair. There is good evidence that male pattern baldness results from an over-sensitivity of scalp hair follicles to DHT, rather than raised levels of either sex hormone in the blood.
Medicines may also help slow or prevent the development of common baldness. In market, there are so many pills for hair loss treatment. However, one famous medicine, Propecia (Finasteride) is available with a prescription. Propecia pill is only for men. Propecia Finasteride is available in dose of 1mg. Moreover, whenever you buy Propecia, you should consult from your family doctor
