Which product is essential for maintaining hair health during coloring?

Deep conditioner is essential for maintaining hair health during coloring because it penetrates the hair shaft more deeply than regular conditioners, providing intense hydration and nourishment. When hair is colored, especially with permanent or high-lift colors, it can become dry and damaged due to the chemical processes involved. Deep conditioners help restore moisture, strengthen the hair structure, and improve elasticity, making it less prone to breakage and damage.

While other options like leave-in conditioners or oil treatments can assist in adding moisture and shine, they typically do not offer the same level of deep nourishment that a deep conditioner provides. Dry shampoo is mainly used for absorbing excess oil at the roots and does not contribute to the overall health and moisture balance of the hair, especially post-coloring.
