How We Choose Every Ingredient

Research First

Each ingredient is selected for its published evidence, from double-blind, placebo-controlled trials to studies on human hair follicle cells.

Forms Your Body Can Use

We choose bioavailable forms like patented Cynatine® HNS keratin and chelated zinc and selenium, then add BioPerine® to help your body absorb more.

Built as a System

Each formula targets a different driver of thinning hair: nutrition, scalp environment, damage to the hair itself, and stress and sleep.

A Note on Timing

Why We Say 90 Days

Hair grows slowly, and each follicle's growth cycle runs for months, not days. That's why the Cynatine® HNS clinical trials measured results at 90 days, and why we ask you to give HAIRLOVE a full three months of daily use before judging your results. The changes start beneath the scalp long before you see them in the mirror.
