Kitchen wisdom often gets tossed aside in favor of heavily researched medications. While it makes sense to choose a treatment with a documented record of success, it also means you might miss the benefits of inexpensive, natural treatments such as cayenne pepper. No scientific evidence, as of April 2011, indicates that cayenne pepper restores hair, but that might indicate it hasn't been rigorously studied for this purpose. If you experiment for yourself, you might find that cayenne's reputation for restoring hair is more than an old wives' tale.
Pour one cup of vodka into a dark, glass jar with a lid.
Stir in 1/4 cup of high-quality cayenne pepper. Purchase your cayenne from an herbal store or certified herbalist rather than from the grocery store to obtain maximum purity and potency.
Close the jar and place it in a cool, dark place for two weeks. During that time, the medical properties of the cayenne, such as capsaicin, vitamin A and flavonoids, can permeate throughout the liquid.
Line a mesh strainer with cheesecloth. Strain the mixture, retaining the liquid portion.
Rub a small amount of the mixture in a spot on the back of your neck to test for irritation, stinging or burning. Wait 24 hours and proceed if your skin test doesn't cause a negative reaction.
Rub the liquid into your scalp twice daily in the places you want your hair to regrow, recommends Jude Williams, certified herbalist and author of "Jude's Herbal Home Remedies." Williams goes on to say that when you stop the treatment, your hair regrowth will also stop.
