There are a number of herbal supplements available that claim to work as a hair loss treatment. Biotin has not had any clinical studies on human beings showing that it combats hair loss or regrows hair. Biotin is a nutritional supplement that has been around for years and is taken orally. There is some preliminary evidence that hair loss can be reduced when biotin is taken by mouth in combination with zinc while a cream containing the chemical compound clobetasol propionate is applied to the skin. But the finding is not conclusive.
Currently there are only 3 hair loss medications on the market: finasteride (marketed as Propecia), which you take orally, Revivogen and Tricomax, which are applied topically
