A sensible pre-blow-dry spray for frizzy, dull hair that gets styled smooth with a brush. It does little for air-dried hair, because the formula needs dryer heat to activate.

Overview
Blow-drying activates this shine spray, which goes on damp, towel-dried hair and smooths as the brush pulls each section straight. Vegan keratin and argan oil coat the hair fiber for reflection and frizz control, with heat protection built in.
Shine, smoothing and heat protection arrive in one spray applied before the dryer. The formula depends on brush tension and blow-dryer heat, so wash-and-go and air-dry routines lose most of the effect.
Who it's for
Dry, frizz-prone hair that is blow-dried sleek most mornings gets shine, smoothing and heat protection in one step. People who let curls dry naturally or need firm hold should choose another product.
Pros and cons
- Heat protection built in
- Lightweight, non-greasy, non-sticky
- Keratin and argan oil for smoothing
- Leaping Bunny approved
- Needs blow-dryer heat to activate
- Directions assume brush tension while drying
- Smoothness claim measured against unwashed hair
Performance notes
The spray coats the hair fiber, and blow-dryer heat activates the smoothing complex while brush tension straightens each section. Smoother cuticles reflect more light, which is where the shine comes from. Skip the dryer and the activation step never happens.
