Male-pattern hair loss is the commonest type of hair loss in males. It usually follows a distinctive pattern of receding hairline and hair thinning on the crown, and is caused by hormones and genetic predisposition to excessive hair loss. Hair grows approximately an inch every couple of months. Each hair grows for 2 to 6 years, remains at that length for a short period of time, then falls out. Shortly a new hair begins growing in its place. At any one time, approximately 85% of the hair on your scalp is in the growing stage and 15% is not. Normally, an enzyme in hair follicles converts testosterone to dihydrotestosterone (DHT). DHT stimulates the growth of hair, but also diminishes hair follicles on the scalp, leading to thinner, fuzzier growth. A genetic predisposition to undue hair loss, coupled by high levels of testosterone and DHT, can adversely impact upon scalp hair growth. Baldness occurs when the number of hair shedding exceeds the rate of re-growth or when the re-growth is finer and/or shorter than the hair that is shed. Male-pattern hair loss is not considered a medical condition, but it may badly influence self-esteem or lead to anxiety. Treatment is not compulsory if you are comfortable with your physical appearance. Hair weaving, hairpieces, or change of a hairstyle may conceal excessive hair loss. This is commonly the least expensive and the most secure option to male hair loss. Nonetheless, if you are not comfortable with your physical appearance, medicines may help decelerate or preclude the development of excessive hair loss. Rogaine (minoxidil) is a drug that can be rubbed directly on the scalp twice daily to treat excessive hair loss. Trials display it can slow hair loss in up to 90% of males who apply it. It helps re-grow hair in 10% to 20%. As soon as the application is stopped, re-grown hair falls out. Propecia (finasteride) is taken once a day in a pill form. Propecia slows down the conversion of testosterone to DHT, thus helping to preclude the diminishing of hair follicles. The medication must not be taken by females, since it may lead to birth deformities. A diversity of surgical treatments involving hair follicle transplantation and other procedures are also available. Hair follicle transplantation normally includes several transplantation sessions and may be expensive. Results, nonetheless, are frequently excellent and permanent. You should discuss these options - or any concerns you have about baldness - with your family doctor. |
