Product Insights

Gliss Shampoo Supreme Length is a 250 ml liquid shampoo formulated to promote longer, stronger hair. It contains conditioning actives such as biotin, apricot kernel oil and Paeonia lactiflora root extract that are intended to reinforce the hair shaft and support growth. However, the formula relies heavily on surfactants like sodium laureth sulfate and a blend of synthetic fragrances and allergens, including linalool, limonene and benzyl alcohol, which may cause irritation for sensitive scalps.

Comparative Analysis

Positioned as a length‑enhancing, salon‑style shampoo, it targets consumers seeking stronger, longer hair while differentiating itself with biotin and apricot kernel oil, but its formula relies heavily on surfactants and fragrance compounds that place it in the mainstream synthetic‑cleaner segment.
