Belangrijkste feiten in één oogopslag

Hoe het vermoedelijk werkt

It may mildly reduce the enzyme (5-alpha reductase) that turns testosterone into DHT.

Wat het onderzoek zegt

Small studies show modest benefit in some people; head-to-head, finasteride works better.

Hoe het wordt gebruikt

Taken as capsules or used in shampoos and serums.

Why DHT appears in the conversation

Pattern hair loss involves inherited sensitivity of some follicles to androgens, including dihydrotestosterone (DHT). Saw palmetto extracts have been studied for effects on the enzymes involved in androgen metabolism. Extracts differ by preparation, so a proposed mechanism does not guarantee that a supplement or shampoo reaches follicles at a useful amount.

The strongest medical evidence for changing DHT in male pattern hair loss belongs to prescription finasteride, which has a different regulatory status and risk profile. Calling saw palmetto 'natural finasteride' obscures those differences.

What the hair studies can tell us

Hair-specific trials of saw palmetto are relatively small and use different preparations, combinations and outcome measures. That makes it hard to predict benefit from a product on the shelf. Evidence is insufficient to present it as a replacement for approved topical Minoxidil or prescription options. A product may still be a personal preference, but it should be chosen with realistic expectations.

Safety and interactions

'Plant-based' does not mean risk-free. Supplements can cause digestive complaints and may complicate medication decisions. Tell a clinician or pharmacist if you use blood thinners, have a planned procedure, are pregnant or could become pregnant, or take any hormone-related medicine. Supplements are not regulated as drugs for hair-loss effectiveness in the United States.

FOLIGAIN® and other options

FOLIGAIN® Minoxidil and other labeled OTC Minoxidil products are studied drug options for hereditary thinning; they do not block DHT. Saw palmetto supplements and cosmetics are different categories. A clinician may also discuss prescription treatments when appropriate. Compare the actual intended use, evidence and risks rather than choosing based on the word 'natural'.
