The most important thing to do to maintain healthy hair is to keep it clean and conditioned. Make sure to wash your hair regularly with a gentle, sulfate-free shampoo that is tailored to your hair type. Conditioner can help strengthen your hair by adding moisture, protein, and shine. Avoid using too much heat styling products on your hair as this can cause damage. Lastly, try to avoid over processing your hair such as bleaching or coloring, which can lead to breakage and dryness.
