Brand: "Health is the result of daily efforts" – that's our brand motto. AFC crafts high-quality dietary supplements and skincare at affordable prices. We handle all production processes in-house, from sourcing raw materials to sales, including advertising and delivery. This optimization allows us to eliminate unnecessary costs and offer the most accessible prices for health products.

Purpose: Our salon-grade low-acid shampoo is gentle on the scalp, hair, and hands. Developed with a focus on hypoallergenicity – it's a product that won't irritate the scalp or hands during use. The amino acids in the formula provide sufficient hydration and smoothness to the hair, eliminating the need for a conditioner.

For Whom:

  • Ideal for those with sensitive scalp.
  • Perfect for those concerned about dryness and hair breakage.

Unique Features: This hypoallergenic shampoo is free from petroleum-based surfactants, silicones, and synthetic dyes.

How It Works: Infused with 15 plant-derived amino acids.

  • Amino acids moisturize the scalp and deep layers of the hair, restoring even the driest and most damaged locks.
  • Smooth the hair cuticle.
  • Strengthen the hair structure.
  • Make the hair more manageable and shiny. Sakura leaf extract soothes excessively dry and itchy scalp, making the hair less brittle and increasing elasticity. Sakura nourishes hair roots and enhances hair density. Japanese Laminaria extract maintains the natural water balance of the hair and scalp. The seaweed normalizes sebum production, eliminates stickiness and greasiness, and improves hair growth.

How to Use: Wet your head thoroughly and apply the shampoo. Lather, massage for a few minutes, and rinse thoroughly.

Volume: 370 ml
