Biotinoyl tripeptide-1
Biotinoyl tripeptide-1 is biotin attached to the GHK peptide; the only hair-growth data are manufacturer claims.
What it is
Biotinoyl tripeptide-1 is the GHK peptide (see GHK-Cu) chemically linked to biotin. It is the peptide part of the supplier blend Procapil, which also contains oleanolic acid from olive and apigenin. It is a cosmetic ingredient.
How it works
The supplier says it strengthens the anchoring of the hair root. This is a marketing claim, and no peer-reviewed paper confirming it was found.
What the studies show
- A search of the medical literature for biotinoyl tripeptide-1 or biotinyl-GHK with hair terms found no study of this molecule.
- The supplier's material describes a 4-month placebo-controlled study of the Procapil blend in women with early female pattern loss, but the full documents could not be checked, and as sponsor material on a blend it cannot isolate this peptide.
How it's used in studies
The supplier recommends a 3% level for the blend (manufacturer data).
Side effects and safety
No problems have been reported, but there are no data. Biotin taken by mouth can distort some lab tests; topical use is not known to.
Bottom line
Marketing claims only. It is possibly harmless and possibly useless. Spend money on proven treatments first.
