How Hairavie handles evidence
Your pattern isn't your whole hair profile
Pattern, porosity, strand thickness, density, scalp behaviour, chemical history and climate are separate readings — and Hairavie is explicit about which actually influence a Hair Match.
Ingredients aren't good or bad in isolation
A silicone can mean slip, shine and less friction. Whether it suits you depends on the formula and your routine. Hairavie analyses formulas, never fear lists.
Missing data lowers confidence, never invents certainty
Ingredient lists don't reveal concentrations. When formula data is incomplete, Hairavie says so instead of pretending to be sure.
Hairavie provides cosmetic hair-care education only. It does not diagnose or treat medical or scalp conditions. If symptoms persist or you're concerned about hair loss or scalp health, consult a qualified healthcare professional.
