Our Take

A glycerin-free strong-hold gel from the Seal + Shield range, specifically formulated to resist humidity and keep curls defined in damp or warm conditions. Where glycerin can cause curls to absorb atmospheric moisture and frizz, this formula seals the cuticle instead. Firm hold with no crunch when scrunched out correctly. Layer over the Seal + Shield Curl Cream for a fully glycerin-free, humidity-resistant routine — a combination that has quickly built a following in the UK curly community for its performance in changeable weather.

How to Use

Apply to soaking wet hair after your leave-in conditioner or curl cream. Smooth over each section and scrunch upwards to form a cast. Allow hair to dry fully — either by air drying or diffusing — before scrunching out the cast for soft, glossy curls.
