Professional cosmetics have a secret: the pH of the water is the pH of the salon. With 30 years of experience in hairdressing, we know that clients' biggest mistake is not hair dyes, but the shampoos they use at home.
Have you noticed that your hair never looks the same when you wash it yourself? It's not just the drying, it's the chemistry. Supermarket shampoos often have a very high pH (very alkaline) that opens the hair fiber's cuticle to clean thoroughly. The problem is that an open cuticle allows moisture to escape, fades color, and "dulls" the shine.
The Ryōho mid-lengths to ends approach: Our professional shampoos are formulated with a slightly acidic pH, identical to that of the scalp. This seals the cuticle, trapping moisture and keratin. It's like an invisible shield.
Cellular-level Hair Reconstruction: When the hair fiber is severely damaged, natural keratin disappears. Our reconstructive treatments not only plug the fiber's pores but also provide micro-molecules of vegetable keratin that penetrate deeply, repairing the structure from within. It's not superficial softness; it's structural hair health.
