YOUR SCALP - YOUR HAIR CARE ROUTINE WILL THANK YOU WITH DUOLOGI Scalp Massager - A dedicated build-up breakdown tool designed to promote blood flow to the scalp, and promote hair health. Strong, flexible bristles gently exfoliate while massaging the scalp, helping to remove debris and build up of dead skin cells and excess sebum from the hair roots. In addition to refreshing the scalp, the gentle massage action helps release tension and pressure for a relaxing spa experience at home. Use with Deology products to promote scalp care and promote healthy looking hair. Apply the product, then massage the scalp in circular motions with constant gentle pressure for a comfortable scalp experience. The scalp massager works well on wet hair paired with scalp scrubs, scalp strengtheners and shampoos, however it can also be used alone - and on dry hair - to quickly refresh the scalp.
