Hair loss is a common problem that affects millions of men and women around the world. While there is no cure for baldness, there are treatments available that can help slow down or even reverse hair loss. In this article, we take a look at the evidence behind the most popular hair loss products and treatments, and explore what experts say about their effectiveness.The only two drugs approved by the U. S.
Food and Drug Administration (FDA) for treating hair loss are minoxidil (Rogaine) and finasteride (Propecia). Minoxidil was originally developed to treat high blood pressure, but researchers found that one of its side effects was hair growth in unexpected areas. The American Hair Loss Association states that most experts agree that minoxidil is “a relatively ineffective drug in combating hair loss”. The treatment has no effect on the hormonal process of hair loss and its benefits are temporary; hair loss continues if use is discontinued.
Finasteride inhibits 5-alpha-reductase type II, which is the enzyme responsible for converting testosterone into the most potent androgen DHT. DHT levels are reported to be reduced by 60 percent when the medication is taken, preventing susceptible follicles from being affected by the hormone and returning to their normal size. This treatment doesn't work on women, and its effect only lasts for as long as it's taken. Dutasteride (Avodart) is used to treat prostate enlargement.
Although the drug has not been approved by the FDA to treat alopecia, doctors sometimes prescribe dutasteride in an unauthorized way for male pattern baldness. Dutasteride works similarly to finasteride, but may be more effective.Over-the-counter (non-prescription) minoxidil comes as a liquid, foam, and shampoo. To be more effective, apply the product to the skin of the scalp once a day for women and twice a day for men. Many people prefer the foam that is applied when the hair is wet.
Allawh recommends 5 percent formulations for maximum effectiveness.It won't rescue a receding hairline, but it stimulates hair growth, although scientists aren't quite sure how it works. Clinical trials published by the Journal of Investigative Dermatology found that a daily dose of 1 milligram of finasteride stopped hair loss or increased hair growth in up to 90% of men.And don't be discouraged if you notice any initial detachment, he says. Consistent use of Rogaine for months has been shown to have favorable results for both sexes. In fact, Rogaine works so well that I warn all my patients to avoid applying it to non-alopecia areas (such as the face) to avoid unwanted hair growth.Since androgenetic alopecia affects so many people, a permanent cure would not only reduce anxiety in a significant percentage of the population, but would also be economically advantageous for the pharmaceutical company responsible for the discovery.Baldness is an accepted part of the aging process for some and a source of distress for others.
While there is no cure available yet, there are treatments available that can help slow down or even reverse hair loss. With further research and development, we may one day find a magic formula for baldness.
