Increase Hair Density at Roots
Density is decided at the follicle. Two mechanisms drive it, and they are not the same.
Two Mechanisms, One Result
Rosemary phenolics reduce oxidative stress and support circulation at the scalp. Biotinoyl tripeptide-1 acts on anchoring and prolongs the anagen phase. Together they address density from the environment and from the follicle itself.
What the Trial Showed
Panahi, Skinmed 2015: a randomised comparative trial, n = 100, six months. Rosemary matched 2% minoxidil on hair count. Independent, no industry funding. Significantly less scalp itching than minoxidil. It is not a cure and it is not instant.
Building the Routine
Scalp Prep Shampoo clears buildup so the serum reaches the root. Follicle-Boost Serum goes on the scalp, not the lengths. Strand Thicken Conditioner protects the fiber you keep.
