Details

A three amino acid peptide where the famous collagen fragment, Tripeptide-1, aka GHK is combined with Biotin, the well-known supplement for stronger nails and hairs. The result of the combination is Biotinoyl Tripeptide-1, a peptide claimed to be helpful for reducing hair loss and for making the eyelashes appear longer, fuller, and stronger.

As for proof, the manufacturer did some in-vitro (made in test tubes) studies that show that our molecule can promote hair bulb keratinocyte proliferation and also helps optimal hair anchorage by stimulating the synthesis and organization of the adhesion molecules laminin 5 and collagen IV. This means that our peptide might help the hair to be stronger and to stay longer in its place, though these are only in vitro results that might or might not translate to real-world use. 

As for a clinical, made on real people study, the manufacturer did one for eyelash growth with 30 volunteers. Using a mascara with 2% of SpecPed LashLD  (trade name for the diluted, buyable version of Biotinoyl Tripeptide-1), the lashes got longer by 17% and thicker by 19% after 30 days.
