To maintain healthy hair, it's essential to choose the right shampoo and conditioner for your hair type. For example, if you have oily hair, opt for a clarifying shampoo, while dry hair benefits from moisturizing products. Additionally, avoid washing your hair daily to prevent stripping natural oils; aim for 2-3 times a week instead. Regular trims are also crucial for hair health, as they help eliminate split ends and promote growth. Incorporating a weekly deep conditioning treatment can further nourish your hair. Lastly, protect your hair from heat damage by using a heat protectant spray before styling with tools like curling irons or blow dryers.
