Olaplex No. 4 Bond Maintenance Shampoo, Repairs, Strengthens, & Nourishes All Hair Types, Adds Shine & Leaves Hair Feeling Soft, 8.5 fl oz

This unisex haircare product is Olaplex No. 4 Bond Maintenance Shampoo, Repairs, Strengthens, & Nourishes All Hair Types. Most of the work happens at the mid-lengths and ends — the scalp takes care of the roots on its own. Use less than you think and add more if you need it; excess product is the quickest route to a flat, greasy finish. Discounted listings come and go, and rarely at the same shop twice. Store it away from steam and direct sun; both shorten the life of the formula. The best deal and the cheapest sticker price are not always the same listing once delivery is counted.
