Going bald is a fact of life for millions of men. Adults lose about 10,000 scalp hairs each and every day. Hair normally lives for around five years. With male pattern baldness these hairs do not always get replaced and gradually bald areas appear. This process can however take a long time and the age at which you start to lose hair does not necessarily provide any clues as to how long it will be until you define yourself as bald. There are a number of reasons why men start to go bald, but if you are a man between the ages of about 20 to 45 and you start to lose scalp hair, then the chances are 95 per cent certain that you are experiencing male pattern baldness. As the term suggests, male pattern baldness follows a typical sequence or pattern.
The normal cycle of hair growth and loss
The normal cycle of hair growth lasts for 2 to 6 years. Each hair grows approximately 1 centimeter (less than half an inch) 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. However, some people may experience excessive (more than normal) hair loss. Hair loss of this type can affect men, women and children.
Male Pattern Baldness
The male pattern baldness form of androgenetic alopecia accounts for more than 95% of hair loss in men. By age 35, two-thirds of UK and EU men will have some degree of appreciable hair loss and by age 50 approximately 85% of men have significantly thinning hair. About 25% of men who suffer from
male pattern baldness begin the painful process before they reach 21.
Most men who suffer from male pattern baldness are extremely unhappy with their situation and would do anything to change it. Hair loss affects every aspect of their life. It affects interpersonal relationships as well as their professional life. It is not uncommon for men to change their career paths because of hair loss.
The Causes of Male Pattern Baldness
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.
Propecia Hair Loss Treatment Pills
Finasteride is the generic name for the brand name drugs Propecia. Finasteride was originally developed by the pharmaceutical company Merck as a drug to treat enlarged prostate glands.
During the trials on men with prostate problems, researchers noted an intriguing side effect: hair growth. Since finasteride had already been approved by the FDA to treat enlarged prostates in men, Merck decided to pursue the possibility of developing finasteride as the first pill to treat male pattern baldness.
In December 1997, the FDA approved a 1mg dose of finasteride for the treatment of androgenetic alopecia (male pattern baldness) in men. Propecia is the first drug in history to effectively treat male pattern baldness in the majority of men who use it.
