Moroccanoil Shampoos are very concentrated and don't contain sulfates (the ingredients that makes shampoo lather). As they don't typically lather right away, it is a basic instinct to add more Shampoo. However, the opposite is actually needed!
The Shampoos are very concentrated and require less product - and more water to distribute evenly. If too much product is added and not enough water to distribute evenly, it can be harder to rinse out.
To use, we recommend applying the Shampoo in a minimal amount beginning at the mid-lengths of the hair and then spreading out evenly throughout the rest. When it feels like you need more product, simply add more water instead to distribute evenly.
