The must have product before styling! Bumble and bumble Prep prepares your hair for styling by detangling and optimising its performance. Its low pH makes the cuticle lie flatter, making your hair shinier and smoother. This rich, strengthening mix of nutrients is invisible and oil free, which is great for natural look and if you don't like the feel of styling products. Prep is also ideal for preparing your hair for cutting as it lubricates the blade and dampens your hair, without water.
