Why we rate it
Lift exactly where fine hair falls flat: at the roots. The precision nozzle puts the spray right where you need it, so you can target the crown or the parting without weighing down the lengths. Towel-dry your hair, spray close to the scalp section by section, then blow-dry with a round brush, lifting at the roots as you go. It gives a soft, touchable hold and sets you up for a long-lasting, bouncy blow-dry.

How do I apply Paul Mitchell Extra Body Root Boost?
Towel-dry your hair, then spray close to the scalp section by section using the nozzle. Blow-dry with a round brush, lifting at the roots as you go.
Is Extra Body Root Boost good for fine hair?
Yes. It's made to give targeted lift where fine hair falls flat, with a soft, touchable hold, and Paul Mitchell lists it as vegan, paraben-free and colour-safe.
Root Boost or Thicken Up: what's the difference?
Root Boost is sprayed at the roots through its precision nozzle for targeted lift, while Thicken Up is a styling liquid worked through from roots to ends to make each strand look and feel thicker. You can use both: Thicken Up through the lengths, then Root Boost at the roots before you blow-dry.
Which size of Extra Body Root Boost is best value?
The 500 ml works out lowest, at £7.59 per 100 ml, against £9.98 per 100 ml for the 250 ml and £18.60 per 100 ml for the 75 ml, which is handy for travel or trying it out.
