Procapil® (Biotinoyl Tripeptide-1)

Biotinoyl Tripeptide-1

A biotin-linked peptide dosed at the supplier's tested 3% — its anagen figure is manufacturer-funded, and we say so.

About This Ingredient

Biotinoyl Tripeptide-1 is the peptide core of a complex dosed in our serum at 3% — the level the supplier tested.

The receipt: a four-month manufacturer in-vivo reported anagen density at +121% versus −37% for placebo (Sederma data — manufacturer-funded; read the methods).

What it does not do: there is no independent RCT on this peptide alone. The independent peptide receipt in our density line is the biochanin-A + acetyl-tetrapeptide-3 trial (Lueangarun 2020). We keep the two stories separate.

Key Benefits

  1. Anagen Support (Manufacturer Data)

    In a four-month manufacturer in-vivo, anagen density moved +121% versus −37% for placebo (Sederma — manufacturer-funded, disclosed).

  2. Microcirculation Activated

    Improves blood supply to the dermal papilla so oxygen and nutrients reach where hair is produced.

  3. Tensile Resistance

    Strengthens the inner root sheath so each strand is harder to pull out when brushing or tying hair.

  4. Prolonged Anagen

    Extends the follicle’s active growth phase: more time producing hair, less time resting.
