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

The shampoo is generally well‑suited for normal to dry hair thanks to its conditioning ingredients, but the presence of sodium laureth sulfate, fragrance and preservatives can be irritating for very sensitive or allergy‑prone scalps; oily scalps may find it slightly stripping if used daily, so occasional use is recommended.

What does hydrolyzed keratin do in Gliss Kur Ultimate Repair Shampoo?

Hydrolyzed keratin penetrates the hair shaft, filling gaps in the cuticle and reinforcing the protein structure; this helps improve strength, reduce breakage, add smoothness and restore shine to damaged hair.

How often should Gliss Kur Ultimate Repair Shampoo be used, and does it contain any controversial chemicals?

For most users, 2–3 applications per week are sufficient; daily use may be too harsh because of sodium laureth sulfate. The formula also contains dimethicone, PEG‑based surfactants, fragrance, and preservatives such as phenoxyethanol and methylparaben, which some consumers consider controversial.
