There are a few medications proven to stop hair loss, or even reverse the balding effects of hair loss.

Finasteride/Propecia

Finasteride (marketed as Proscar, Propecia) works by blocking the enzyme, Type II 5 alpha-reductase, and in doing so it reduces the level of the hormone in the scalp which shortens the hair growth cycle and allows hairs to revert to a normal growth cycle. This can, in turn, stop hair loss and increase new hair growth in men with male pattern baldness (androgenetic alopecia). Continuous use once a day for 3-6 months is required before benefit is seen, and effects are reversed 6-12 months after treatment is discontinued so continuous use is recommended to sustain benefit.

Additionally, it is registered in many countries as a hair loss treatment for androgenetic alopecia (male-pattern baldness) as well as FDA approved.

Side effects

When taken at the recommended dose, the possible side effects of Finasteride are usually mild and generally have not caused the men to stop taking the medicine.

Possible side effects identified with Finasteride include decreased libido, erectile dysfunction, decreased volume of ejaculate, breast tenderness and enlargement; rashes, itching and swelling of the lips and face; and testicular pain. These are reversed after treatment is discontinued.

Regaine/Minoxidil

Minoxidil is a vasodilator and originally was exclusively used as an oral drug (Loniten®) to treat high blood pressure. It was, however, discovered to have the interesting side effect of hair growth and reversing baldness, and in the 1980s, Upjohn Corporation produced a topical solution that contained 2% minoxidil to be used as a hair loss treatment, to treat baldness and hair loss, under the brand name Rogaine in the United States, and Regaine outside the United States.

Treatments usually include a 5% concentration solutions that are designed for men, while the 2% concentration solutions are designed for women. It is unknown how the drug stimulates hair growth, however some experts believe minoxidil dilates the blood vessels around hair follicles, increasing the nutrient supply and encouraging increased hair growth.

Application

Two daily applications for up to four months may be required before any results are observed. If hair regrowth occurs, two daily applications are necessary for additional and continued hair growth (unless your doctor

It is important to continue to use minoxidil for the entire time prescribed by your doctor, even if hair growth does not appear within several months. If there is no hair growth after at least four months or more, consult with your doctor, as this medication may not be effective for you.

Vitamins For Hair
