Is Power & Strength shampoo suitable for sensitive or dry scalp and hair?

The shampoo’s high‑strength surfactants (Sodium Laureth Sulfate and Cocamidopropyl Betaine) can be drying, so it may not be ideal for very sensitive or extremely dry scalps, though the added Panthenol and Hydrolyzed Keratin help provide some moisture and repair for normal to slightly dry hair.

What does Hydrolyzed Keratin do in this shampoo and how does it benefit hair?

Hydrolyzed Keratin supplies short protein fragments that can temporarily bind to damaged hair fibers, helping to smooth the cuticle, improve strength, and reduce breakage when used regularly.

How often should I use this shampoo and does it contain any controversial chemicals?

It is recommended to use the shampoo 2‑3 times per week; the formula includes common preservatives (Sodium Benzoate, Phenoxyethanol) and fragrance ingredients (Parfum, Hexyl Cinnamal, Linalool) that some consumers consider controversial or potentially irritating.
