I paid dearly this time my smoothing. Scalp burns, with crust on the surface. Film per tonne. Could not wash my hair, all roots were glued by scabs, unable to do anything about it either !! The dermatologist looked stunned and quite worried. One week to find an acceptable head. A galley week and also died of worry of losing the entire mop. Never again for me this brand. Do not get fooled like me, with the previous comments.
