Purple Shampoo Bar with Biotin – Blonde & Gray | VIORI

A purple toning shampoo bar with biotin and rice water for blonde and gray hair. Brass creeps into blonde and gray hair fast. This purple shampoo bar neutralizes yellow and orange undertones while strengthening hair with biotin and Longsheng rice water. The purple pigment comes from sweet potato powder — not synthetic dye — so it tones without staining or drying. Made with the same fermented rice water the Red Yao women of southern China are known for using as their primary hair treatment. Biotin reinforces keratin to keep color-treated or aging hair strong and flexible. Most purple shampoos strip moisture — this one adds it back. Scent: Calming lavender — soothing and spa-like. Not too sweet, not too herbal. What it feels like: Lathers with a light purple tint. Rinses clean. Hair feels toned and cool immediately — brassiness is visibly reduced after the first wash. No dryness. Use 1–2 times per week for maintenance toning. For heavy brassiness, use 3 times the first week, then reduce to once weekly.
