Biochemistry supports saw palmetto . If it turns out that saw palmetto helps prevent hair loss, it would be the herb for men, since studies have shown that it also helps prevent prostate enlargement. You could prepare a baldness-prevention shampoo by adding licorice to your favorite shampoo when you shower. For centuries, if not millennia, both men and women have massaged their scalps with rosemary in olive oil to keep their hair lush and healthy. Massaging the scalp certainly stimulates circulation and encourages hair growth, according to Wilma F. Bergfeld, M.D., of the Cleveland Clinic Foundation in Ohio.
Naturopaths often suggest nightly scalp massage with one part rosemary oil and two parts almond oil.
Danshen is actually Asian red sage . In folklore, both danshen and native sage have long-standing reputations as hair preservers. In this country, people frequently used sage extracts in hair rinses and shampoos. The herb allegedly had the ability to prevent hair loss and maintain hair color. This folk use of herbs is unlikely to cause any harm, so I suggest that you try adding a few teaspoons of sage tincture to your favorite shampoo.
