S-7 Daily Shampoo

A daily shampoo developed in San Francisco by a Japanese hairdresser — for people who wash often and want a gentle, balanced clean.

What is S-7?

After about a year of refining in the salon, S-7 is now in its final packaging and label stage. Formulated with hydrolyzed silk protein for a soft, silky lather, it's a salon-crafted daily shampoo made for frequent washing — leaving hair feeling clean, light, and balanced.

Why S-7 is different

- Made for daily, frequent washing
- Salon-crafted and refined batch after batch on real hair
- A gentle, silky lather with hydrolyzed silk protein
- MATSUYAMA — a Japanese citrus-and-forest-inspired aroma
