These two products are both designed as anti-hair fall shampoos to strengthen weakened hair and reduce hair loss. However, the choice between them should be based on your specific hair type. The Genesis Bain Nutri-Fortifiant Shampoo uses a richer formula, making it ideal for individuals with thick and dry hair. On the other hand, the Genesis Bain Hydra-Forifiant Shampoo features a lightweight formula tailored for those with thin or oily hair types.
