Scalp Serum

This haircare product is Scalp Serum by Ouai. Hair type does most of the deciding: what thick, coarse hair needs will weigh fine hair down. Use less than you think and add more if you need it; excess product is the quickest route to a flat, greasy finish. Whether it is discounted this week says more about the shop's stock than about the product. A clarifying wash every few weeks clears build-up and lets the rest of the routine work again. The cheapest listing is not automatically the best deal: delivery and any code applied at checkout decide that.
