FAQs
- Biotin, Biotinyl-GHK, biotinoyl-tripeptide-1… are they not the same? Biotin, Biotinyl-GHK, and Biotinoyl-Tripeptide-1 are different compounds with distinct functions.
- Biotin: the darling of hair products. Biotin may support hair health, but its effectiveness varies and is often overstated.
- Biotinyl-GHK: a miracle ingredient against hair loss? Biotinyl-GHK (biotinoyl tripeptide-1) is a cosmetic ingredient, not an approved hair-loss medicine; the published studies test it only inside multi-ingredient complexes such as Procapil, so no result can be attributed to the peptide itself.
- Vitamin B7: is it the ultimate secret to healthy hair or just a myth? Biotin is important for hair health, but supplementation is often unnecessary for most people.
- Vitamins vs. minoxidil: who wins the battle for hair growth? Minoxidil is generally more effective for hair growth than vitamins.
- How much biotin is too much biotin? The NIH Adequate Intake for adults is 30 mcg of biotin a day, and supplements often contain hundreds of times that; no toxic dose has been identified, but the FDA warns that high-dose biotin can distort blood tests including troponin, so tell your doctor and the lab before any test.
