Purple Shampoo Bar with Biotin – Blonde & Gray | VIORI

Who it's for: Blonde, highlighted, gray, silver, white and salt-and-pepper hair that turns yellow or brassy between washes. Works on fine, thick, straight, wavy and curly hair, and on beards going gray.

What it does: Neutralizes yellow and orange undertones so blonde reads cooler and gray reads brighter and whiter — while biotin and Longsheng rice water leave hair soft instead of stripped.

How it works: Natural purple pigment from sweet potato powder cancels warm tones on the color wheel. Fermented rice water delivers inositol and amino acids into the hair fiber. Biotin supports keratin so color-treated and aging hair stays strong and flexible. No sulfates, so the cuticle isn't blasted open to deposit color — the reason most purple shampoos leave hair like straw.

What it feels like: Rich lather with a light purple tint. Rinses clean, no residue. Hair feels cool-toned and soft right away; brassiness is visibly reduced after the first wash and keeps improving over the first few weeks.

Scent: Calming lavender — soft and spa-like, not sweet, not herbal. Doesn't linger.

How to use: 1–2 times per week for maintenance. For heavy brassiness, use 3 times the first week, then drop to once weekly. Pair with the Purple Conditioner Bar to seal in moisture.
