Bumble and bumble While You Sleep Masque is an overnight treatment for swingy, silky (de-stressed) strands by A.M. It helps to reverse the appearance of damaged hair. The overnight masque infused with Evening Primrose helps repair past wear-and-tear – and fortify against future damage. The product is free from parabens, phthalates, mineral oils, and formaldehyde.
How to use:
Apply on dry hair once or twice a week. For deep nourishment, leave on overnight – and then wash out with your favorite Bb.Shampoo and Conditioner. After cleansing, use Save the Day Daytime Damage Repair Fluid for around-the-clock repair.
