Today, saw palmetto is used as an ingredient in many hair growth products and supplements, as it is thought to prevent hair loss. This could be due to saw palmetto's influence on the hormones that dictate hair growth.
Saw palmetto for hair loss
There is evidence to suggest that saw palmetto can help treat hair loss and prevent its occurrence. According to a 2012 study, saw palmetto could inhibit 5-alpha reductase (5-AR). 5-AR converts testosterone, a male sex hormone, into a more potent hormone called dihydrotestosterone (DHT).
Research shows that high levels of DHT can shrink hair follicles and result in hair loss. DHT also makes it harder for hair follicles to grow new hair once the old hairs fall out. By inhibiting 5-AR, saw palmetto blocks the conversion of testosterone to DHT.
In another 2012 study, researchers evaluated the effects of saw palmetto supplementation in men with mild or moderate androgenetic alopecia, or male-pattern baldness. One group received 320 milligrams (mg) of saw palmetto every day for two years, while another group took one mg of finasteride, a conventional drug used to treat hair loss.
The results showed that 38 percent of participants who supplemented with saw palmetto experienced improvements in hair growth, compared to 68 percent of those who supplemented with finasteride.
While the experiment showed that finasteride was more effective, the researchers noted that saw palmetto may be less likely to work in people with more severe cases of hair loss. More research is needed to confirm this.
Saw palmetto is available in several forms, including oral supplements and hair care products like conditioners and shampoos.
Due to limited research on the use of saw palmetto for hair loss, there is no official recommended dosage for it. That said, a study published in the Journal of Cutaneous and Aesthetic Surgery cited a recommended dosage of 160 mg twice daily for saw palmetto tablets. Researchers often use this dosage when studying with saw palmetto.
Take note that saw palmetto has been reported to sometimes cause mild side effects, such as headaches and stomachaches. If in doubt about using saw palmetto, consult a natural health practitioner.
Other natural remedies for hair loss
Hair growth depends on several factors, including a person's genetic makeup. Still, some home remedies might help prevent hair loss and/or encourage hair growth. These remedies include:
- Jojoba oil – Jojoba oil helps nourish hair follicles without leaving any residue behind. It also stimulates hair cells to grow faster.
- Aloe vera – Aloe vera helps get rid of sebum buildup in the scalp. Sebum is a natural oil that helps keep the scalp moisturized. It can build up on the scalp and clog hair follicles due to poor hair hygiene.
- Garlic – The pungent compounds in garlic help increase blood circulation in the scalp, which stimulates hair growth. These compounds also stimulate the synthesis of collagen, a protein that gives structure to hair.
- Onion – Like garlic, onions boost blood flow in the scalp for better hair growth.
- Licorice root – Licorice root helps relieve dry and irritated scalp. It also strengthens weak follicles.
- Rosemary oil – Rosemary oil has antiseptic properties. It is ideal for treating scalp issues that slow hair growth, such as dandruff and bacterial infections.
- Coconut milk – Coconut milk helps moisturize a dry scalp, which is a leading cause of hair loss.
- Apple cider vinegar – Apple cider vinegar works as a clarifying agent, ridding the scalp of extra sebum and other residues that can clog hair follicles and inhibit hair growth.
Some hair loss is natural. But for mild to moderate cases of hair loss, it might help to use herbal remedies, such as saw palmetto, to strengthen hair or encourage hair growth. (Related: Study reveals fermented water chestnuts help with symptoms of balding, hair loss.)
