Even for people who don't go completely bald, hair loss can be a problem. All people - both men and women - lose hair as they grow older. The hair they manage to hold onto becomes thinner and less pleasing to the eye and touch as it used to be. THE FAILURE OF MINOXIDIL In the 1980s, Americans were excited about Minoxidil. Minoxidil was developed as a blood pressure medication by The Upjohn Company. Researchers noticed that as a side effect, the drug grew hair. This "miraculous" abilty reached the public, who clamored for it. Finally Upjohn announced, with great fanfare, that it would seek FDA approval to market Minoxidil (now called " Rogaine") for baldness. As it turns out, however, Rogaine doesn't grow hair very well. Upjohn's latest version of the drug, which was recently approved by the FDA to be sold over-the-counter, is even less likely to work than the prescription version because it is half-strength. After eight years of clinical experience with Rogaine, the results have been mixed. Some people get benefit, others don't. It seems to work better in women than in men. However, it appears that Rogaine is much better at helping people keep and improve the hair they still have than in growing new hair. While some terminal hair does regrow in some people who use Rogaine, less than 10% show enough new growth in bald areas to cover them, especially in front. Those who grow a noticeable amount of hair tend to be people whose hair loss is at an early stage. In people with fine hair, the combination of regrowth plus "deminiaturization" of the existing hair can provide an acceptable cosmetic result about 40-50% of the time. As a bonus, most of these people stop getting balder. However, the expense, the side effects and the lack of efficacy of the drug prevent many people from using it. Although Minoxidil is the only FDA-approved treatment for baldness, people do not have to subject themselves to this drug to grow new hair. State-of-the art hair growth formulas have been developed by physician and scientist Peter Proctor, M.D., Ph.D. ANDROGENETIC ALOPECIA Although hair loss is part of aging, it occurs in young people who suffer from a condition called Androgenetic Alopecia (AGA), which leads to accelerated hair loss. AGA is commonly known as Male Pattern Baldness, but, in fact, occurs in both men and women. The pattern of hair loss varies by gender. With men it usually begins with a receding hair line. In women the pattern is more diffuse, typically sparing the anterior hairline and predominately affecting the crown.
