Biotinoyl Tripeptide-1 Hair & Scalp Serum

It's a leave-in product you apply to the scalp rather than the lengths of your hair. This biotinoyl tripeptide-1 serum hydrates the scalp with an aloe and glycerin base, conditions it with niacinamide, panthenol and botanical oils, and pairs that with biotinoyl tripeptide-1 to support a healthy-looking scalp and the look of fuller hair.

Biotinoyl tripeptide-1 is biotin (vitamin B7) linked to a three-amino-acid peptide. In hair care, it's used to support the look of fuller hair. In this serum it's paired with niacinamide, panthenol and caffeine in a lightweight, leave-in formula for the part and hairline.

It's for anyone who wants a lightweight, leave-in step for the part and hairline that supports a healthy-looking scalp and the look of fuller hair. It suits people who like an aloe base with botanical oils and a short routine: apply, massage, done. It's a cosmetic, not a treatment for hair loss or a scalp condition; for those, see a dermatologist.

Apply it to a clean scalp that's dry or towel-dried. Part your hair, apply along the part and hairline, massage it in for 30 to 60 seconds, and leave it in. There's no rinsing step, so you can apply it at night and style as usual in the morning.

Caffeine is a common scalp-care ingredient. In this serum it works alongside niacinamide and panthenol in a lightweight, leave-in formula that supports a healthy-looking scalp.

Patch test a small area first, especially if you're sensitive to essential oils, since the formula includes rosemary leaf oil. It's for external use only, so don't swallow it, and avoid contact with your eyes and mouth. If irritation occurs, stop using it. If you take prescription medications, check with your physician before use. Store it in a cool, dry place away from sunlight, and keep it out of reach of children.
