This type of treatment is therefore applied after rinsing out the deep conditioner on damp hair and before styling.
The action of leave-in treatments is essential because it enhances the effect of the hair mask by penetrating the hair for immediate and longer-lasting action. In short, they condition the hair until the next shampoo, thus maintaining its good balance.
Leave-in treatments can come in different textures: cream, milk, or even liquid spray. They should be applied along the entire length of the hair, down to the ends.
As with deep conditioners, there are certain categories of leave-in treatments often classified into two groups: moisturizing and protein-based. These two categories serve the same objectives as deep conditioners. That said, their greater cosmetic dimension can be noted, as moisturizing leave-in treatments will most often aim to soften the hair. As for protein-based ones, they will address a need for strengthening, coating the hair, and also shine. It should be noted that protein-based leave-in treatments are also intended to serve as heat protectants.
Regarding composition, moisturizers will contain most of the components found in other types of moisturizing treatments. For protein-based ones, many of them will contain silicones or silicone derivatives, hence their action as heat protectants.
