Wella Diaboost Advanced Hair Thickening Serum 100ml

Wella Diaboost Advanced Hair Thickening Serum is a leave-in styling treatment that instantly thickens fine, limp hair. Worked through towel-dried hair before drying, it coats each strand to deliver an immediate boost in diameter and body.

The lightweight formula adds fullness and texture without stiffness or residue, making fine hair easier to style with more grip and volume. Ideal for anyone wanting visibly thicker, fuller-looking hair from the first use.
