I have dull and damaged hair. I want to know how to care for dry, undernourished hair

Invest in a moisturising shampoo and conditioner. Deep conditioning your hair once a week. You can also go for an olaplex service twice a month. Be gentle with your hair as dry hair is prone to breakage. Avoid tugging and begin too rough. Also, make sure to not use excessive heat or styling products on your hair.
