Medium-to-thick, coarse, wavy or curly hair that frizzes in humidity or loses smoothness during heat styling.

Suited to anyone who blow-dries or diffuses regularly and wants a leave-in step that also functions as heat protection, rather than someone looking for a rinse-out treatment.

This treatment combines two jobs in one spray: the silicone film that seals out humidity is heat-activated, so it also functions as a heat protectant, while the hydrating plant oils and panthenol sit beneath that film so hair is smoothed on the surface without staying dry underneath. That dual role is what separates it from a rinse-out mask or a plain heat-protectant spray that doesn't address frizz.

Application steps:

1. Spray onto clean, damp hair from roots to ends.
2. Comb through evenly to fully saturate the hair.
3. Activate with heat: blow-dry using a round brush for a sleek finish, or diffuse for defined curls.
4. Use before each heat-styling session for continued frizz and heat protection.

Given how the formula and format actually work:

Pros:

• The heat-activated silicone blend gives real humidity resistance and doubles as heat protection, replacing a separate heat-protectant spray in the routine
• Lightweight, non-greasy application suits both straight blowouts and diffused curls without weighing hair down
• Hydrating actives (panthenol, aloe, sea buckthorn) sit underneath the smoothing film rather than being blocked by it

Cons:

• Silicone-based film-formers can build up over time on hair that isn't washed periodically with a clarifying shampoo
• Requires a heat-styling step (blow-dry or diffuse) to fully activate; air-drying alone won't deliver the same frizz control
• Contains fragrance and fragrance allergens (limonene, citronellol, coumarin, benzyl benzoate), worth noting for sensitive scalps
