What is saw palmetto and how may it relate to skin and hair health?

Saw palmetto (Serenoa repens) contains fatty acids that may inhibit 5-alpha-reductase, the enzyme that converts testosterone to dihydrotestosterone (DHT). DHT is involved in androgenetic alopecia and may contribute to acne. Some clinical studies suggest saw palmetto may modestly support hair retention in androgenetic alopecia.

What dosage of saw palmetto has been studied for hair loss?

Clinical studies for hair loss have used 200–320 mg of saw palmetto extract per day, standardized to 85–95% fatty acids. Studies typically lasted 12–24 weeks. A small RCT showed 60% improvement in hair quality with 320 mg daily. The evidence base is smaller and less robust than for finasteride.

What are the potential side effects of saw palmetto?

Common side effects include digestive discomfort, headache, and dizziness. Saw palmetto may interact with hormone therapies and anticoagulants. It may affect PSA levels, which could complicate prostate cancer screening. Pregnant and breastfeeding women should avoid saw palmetto due to anti-androgenic effects.

About

Saw palmetto inhibits 5-alpha-reductase enzyme, reducing conversion of testosterone to DHT, which stimulates sebaceous gland activity. A small study found saw palmetto reduced sebum production and acne severity in young men. Most clinical data is from prostate health studies.

How It Works

Inhibits 5-alpha-reductase enzyme, reducing conversion of testosterone to dihydrotestosterone (DHT); DHT stimulates sebaceous gland activity, so reduced DHT levels may decrease sebum production and improve hormonal acne; also has anti-inflammatory properties via COX-2 inhibition.
