My hair had never felt this combination of clean AND cared for! My scalp is happy and my hair is happy. So many volumizing shampoos leave my hair a tangled, dried out mess, but this shampoo is a luxurious treat. One pump is enough for my chin length hair. If my hair feels like it needs a deeper cleansing, I use two pumps or lather twice with one pump each time. Either way, my hair feels full and silky soft.
