Deep Nourishing Hair Mask

Deep Nourishing Hair Mask is the treatment for hair that has gone past what a conditioner can fix — dry, damaged, brittle hair that snaps rather than bends, and hair that has simply gone dull and weak.

Elasticity is the measure that matters here, and it is the one most hair products ignore. Healthy hair stretches and returns; damaged hair stretches and breaks. This mask improves strength and elasticity directly, which is what stops breakage at its cause rather than hiding the ends afterwards. Alongside that it hydrates and revitalises, and seals in moisture for a smoother texture that lasts past wash day.

Gotu Kola, Onion Seeds and Avocado carry it. Gotu Kola is the traditional strengthener, long used to support hair from the root. Onion Seeds are rich in the sulphur compounds that hair is largely built from — which is why onion has become the ingredient people turn to for thinning, weakening hair. Avocado brings the deep fats and vitamins that dry, brittle hair has been starved of.

One tip worth taking: after applying the mask, wrap a warm towel around your head and let the steam work. Heat opens the hair cuticle, and an open cuticle lets the mask penetrate the strand instead of sitting on it. It is optional, and it is the difference between a good result and the best one.
