Which ingredients in this shampoo specifically help with dry or brittle hair?

The formula addresses dryness and brittleness through three main ingredients. Glycerin acts as a humectant, drawing moisture from the surrounding air into the scalp and hair, which reduces dryness and improves manageability. Propylene glycol works similarly, enhancing the water‑binding capacity of the formulation and helping the scalp stay hydrated after washing. Panthenol (provitamin B5) penetrates the hair shaft, contributing to the strengthening of the cuticle and improving overall hair structure, which lowers the tendency for split ends and breakage. Additionally, hydrolyzed wheat proteins form a protective film on the hair surface, giving a smoother appearance and increasing perceived density without weighing the hair down. Together, these ingredients create a balanced environment that supports moisture retention and structural integrity, making the shampoo a practical choice for daily care of dry or brittle strands.
