learn Vitis vinifera

Is Vitis vinifera more effective in oral supplements or topical products? Neither oral nor topical grape extract has been tested for hair loss in a human trial; topical use has only a theoretical, mouse-based rationale.

learn Finasteride

Topical or oral? Choosing between pills and lotions according to your case. In studies, topical finasteride gave much lower blood levels of the drug than tablets but still lowered blood DHT, and whether it causes fewer side effects has not been established. There is no FDA-approved topical finasteride, and the FDA warned about compounded versions in April 2025.

learn Metformin

Is metformin used topically for hair loss, or only as an oral tablet? Approved metformin products are oral tablets only; there is no approved topical metformin for hair loss. Published human reports of topical use are a handful of uncontrolled, pharmacy-compounded case reports in scarring alopecia, and the most-cited clinical series actually used the oral drug.

learn Sulforaphane

Is sulforaphane used in oral supplements or topical hair treatments? Sulforaphane is primarily used in oral supplements, not topical hair treatments.

learn white tea

Is white tea more effective in topical hair products or as an oral supplement for hair growth? Neither topical nor oral white tea has any human clinical trial behind it for hair growth. Topical use has a more direct mechanistic rationale, but the only verifiable studies are a cell-culture EGCG experiment and a pharmacokinetic study with no hair outcomes.
