Even though we read that the main cause for hair loss is from both hormones and genetics, male pattern hair loss is noticed among 95 percent of all individuals suffering from hair loss.
The main role in the male pattern hair loss is played by DHT. The DHT can be controlled by using Propecia.
When your body holds more DHT, the hair follicles become finer and thinner until the hair is permanently falling. DHT is the main hormone used extensively in the early stages of the human population. DHT completely shrivels the hair follicle until it no longer produces noticeable hair.
An evident cause of hair loss is an excess of DHT. The reasons for hair loss are still obscure. But research shows the that men suffering from male pattern hair loss have higher level of DHT particularly in the scalps. In the normal cycle, the hair passes out three phases- Expansion, falling off, and new expansion. The presence of DHT quickens the falling out phase and shortens the expansion phase. This results in hair thinning on the scalp.
In general DHT binds with the genetically vulnerable follicle receptor which is in the hair on the scalp. Propecia prevents the conversion of testosterone into DHT thereby preventing hair loss. Propecia (Finasteride) was called Proscar in early days. This was extensively used to control hair loss.
Propecia prevents hair loss by blocking the enzyme 5 alpha-reductase, which in turn reduces the DHT level in the scalp.
However, Propecia has not been found to restore re-growth in frontal areas. Propecia produces massive results when it has been conjugated with Rogaine especially for hair re-growth in the crown area of the scalp. The frontal hairline area can be restored with hair only by transplant surgery. In addition to this hair loss prevention with Propceia is limited to older men. Better results can be achieved if you have been suffering from baldness for less than 5 years.
Most physicians prescribe Propecia, hair loss halting rather than re-growth and then go for transplantation for the lost hair.
You should remember to take Propecia every day at least 3 to 6 months for getting positive results. Once you stop taking Propecia, the hair loss continues.
Propecia was used to treat prostates in early days. Propecia should not be taken by pregnant women since it may lead to neonatal anomalies. This product should be used continuously for three months to prevent hair loss. But this may have a side effect of lack of sex drive and impotency.
