Even just a few years ago it was very difficult to obtain effective medication against hair loss - there just were not very many medicines available on the market. This situation has since changed, with a large range of different medicines now available. Treating hair loss through medication can lead to already lost hair growing again, though it is just as important to stop or at least reduce hair loss. An important part of any medication for hair loss therefore involves not unduly overstressing existing hair in an attempt to preserve it, i.e. taking preventive measures against hair loss.
Drug-based treatment has a major influence on any subsequent surgical intervention, and the results of medication can often be so good that patients decide against a hair transplant. Or the results of the drug-based treatment are so good that only minor surgery is necessary. At the time of writing there are two medicines available on the pharmaceutical market which can be recommended for treating hair loss: Minoxidil (Rogaine®) and Finasteride (Propecia®).
