Supplement Skeptic · Hair, Skin & Dental

Which hair, skin & dental supplements are worth buying?

Reviews of hair, skin, nail, beauty, and oral-care supplements — where the product usually does something, just not the dramatic thing the page promises.

Every product below carries one of four verdicts. Recommend: the evidence, the disclosed doses, and the price all hold up, and we would buy it ourselves. Conditional: it earns its price only for a specific buyer, and the review names that buyer. Skeptical: the ingredients may be reasonable, but hidden doses, proprietary blends, or claims that outrun the research mean you are mostly paying for marketing. Avoid: we found something disqualifying. To use any review, start at the verdict box, then check the ingredient doses against the studies cited, the real monthly cost, and the refund terms before you get near a checkout page. The who-should-skip section tells you quickest whether a product is even meant for you.
