Is the Gliss product safe for sensitive or acne‑prone scalp?

The formula is generally well‑tolerated, but fragrance and certain silicone‑based polymers can cause irritation on very sensitive or acne‑prone scalps, so a patch test is recommended before regular use.

What role does keratin play in the Gliss formula and how does it benefit hair?

Keratin acts as a protein source that helps replenish the hair shaft, reinforcing the cuticle, improving elasticity, and reducing breakage, which results in smoother, stronger hair.

How often should I apply Gliss and does it contain any controversial chemicals such as parabens or sulfates?

For most hair types, using Gliss two to three times per week is sufficient; the product typically contains mild surfactants and may include sulfates, but it usually avoids parabens, though checking the specific label is advised.
