Hair Loss Phenomenon
We all lose a little hair every day, and 40 to 100 hair follicles is considered normal. That may sound like a lot but a normal scalp would have as many as 100,000 hairs. Each hair shaft grows 0.5 to 1 inch per month for between two and six years then it is shed after a resting period, and a new hair grows. The process is regular and cyclical on a normal scalp and 85% to 90% of hair is growing at any one time. Scientists who have researched the process of hair loss are confident that hair loss experienced by men and women is a condition called "androgenetic alopecia".
In men it is known as male pattern baldness and in many cases progresses to a horseshoe-shaped fringe of hair (a receding hairline) and/or balding on the top of the head. In women it usually results in a general thinning of hair. A combination of factors causes hair loss. Heredity, hormones and age causes a progressive shrinking of the hair follicles that contain the hair shaft. As the hair follicle shrinks the growth cycle shortens, and the rest phase lengthens. The follicles tend to produce hair shafts that are short, thin and barely visible. Hair loss affects a significant proportion of the population and is more prevalent as we age. By the age of 35 almost 40% of men and women show some degree of hair loss. It can start as early as teenage years.
Propecia for Hair Loss
Propecia is an effective prescription treatment to help prevent male pattern hair loss or baldness. Propecia 1mg is a tablet taken orally once a day. Studies have shown that Propecia can prevent further hair loss in 86% of men with male pattern hair loss. The same study also demonstrated that 48% of men had improved hair growth. The active ingredient in Propecia is finasteride, which prevents the formation of DHT (dihydrotestosterone). The development of balding tissue is dependent on the levels of DHT. Propecia is produced by Merck Sharpe and Dohme, one of the largest pharmaceutical companies in the world. We supply generic Propecia.
Propecia mechanism of work
Propecia lowers the levels of a hormone called dihydrotestosterone (DHT) in the scalp and blood by blocking the enzyme that metabolises DHT. Researchers in this area believe male pattern hair loss is due to heredity and is dependent on the levels of DHT. DHT contributes to a shortening of the growth phase and a thinning of the hair. Men with male pattern baldness have increased levels of DHT in their scalps.
How long does it take for Propecia to work?
You may need to take Propecia daily for three months or more before you can see a benefit. Hair grows very slowly, about half an inch a month. Most men begin to see the first benefit of Propecia, slowing of hair loss, after 3 months, and after 6 months begin to experience regrowth. Generally, you will not grow back all the hair you have lost. If the treatment has not worked for you in 12 months, further treatment is unlikely to be of benefit. If you stop taking Propecia, it is likely that you will lose the hair you have gained within 12 months of stopping treatment. There is a small but significant incidence of side effects.
Propecia is not indicated for use in females, and females should not handle crushed or broken Propecia tablets.
Propecia Side Effects
Along with its needed effects, a medicine may cause some unwanted effects. Among these are severe allergic reactions rash; hives; itching; difficulty breathing; tightness in the chest; swelling of the mouth, face, lips, or tongue; breast enlargement, lumps, pain, or tenderness; nipple discharge; testicular pain.
This is not a complete list of all side effects that may occur. Although not all of these side effects may occur, if they do occur they may need medical attention.
