What should you apply after a chemical treatment on hair?

After a chemical treatment on hair, applying conditioner is essential. Chemical treatments, such as relaxers or color treatments, can deplete moisture and create damage to the hair shaft, leading to dryness and brittleness. A conditioner helps to restore moisture, replenish hydration, and improve the overall health and texture of the hair. It often contains nourishing ingredients that can repair and fortify the hair cuticle, making it smoother and more manageable.

Using heat immediately after a chemical treatment is generally not advisable, as the hair is already weakened and can be further damaged by excessive heat. Water alone would not provide the necessary hydration or nutrients needed after such treatments. Hair dye should not be applied right after a chemical treatment, as this can lead to additional damage to the hair and affect the outcome of both the dye and the treatment previously applied. Thus, using a conditioner is the most beneficial choice for hair health post-treatment.
