Based on its formula, is this product safe for sensitive or dry scalps?

It is generally well-tolerated, but the fragrance and silicone agents can irritate very sensitive scalps, so a patch test is advisable before regular use.

What is the specific role and benefit of hydrolyzed keratin in this formula?

Hydrolyzed keratin provides small protein fragments that penetrate the hair cuticle, helping to rebuild weakened strands, reduce breakage and smooth the surface for added shine.

What is the optimal application frequency for this product, and does it contain controversial chemicals?

For best results, use the product 2-3 times per week as a regular shampoo or conditioner; it contains silicones such as dimethicone and synthetic fragrance, which some consumers consider controversial, but it is free of sulfates and parabens.
