Regular oils, serums, and supplements only reach 0.3% of your follicle depth. Scalpi's tiny capsules reach 70%. That is the only number that matters.

The hair you see is already dead. The only living part is the follicle: the tiny root buried under your skin. During perimenopause, your estrogen drops fast, and your scalp ages faster too. The skin gets thinner. Small pockets of irritation start building up. And the follicle stops getting what it needs to grow.








Published research shows Scalpi's formula reaches 70% of the way down your follicle. Regular products only reach 30%. That is not a small difference. It is the difference between treating the root of your hair and just coating the surface.
Each tiny capsule is built from the same fatty material as your skin. When it touches your skin's outer layer, it blends right in and softens that layer just long enough to let the ingredients inside pass through.
Your hair follicle is an open channel that goes deep under your skin. Every time your hair moves, even slightly, it acts like a tiny pump, pulling the capsules further down. Researchers call this the "ratchet effect."
Once it reaches the base of the follicle, the capsule releases Niacinamide, Retinol, EGCG, and Vitamin E right where they are needed. None of it passes through your bloodstream, liver, or stomach.
