Hair care for the sweltering heat

My hair remains oily even after washing it. My scalp is dry, but my hair seems to be oily.

If my hair isn't hydrated, I get a lot of dandruff and my scalp feels tight. My hair gets greasy after washing it with a moisturizing shampoo.

Even if I wash my hair, the effect only lasts for a moment. I think managing my hair is especially difficult in the summer. It’s even harder because I have wavy hair.

Do you have any tips for taking good care of your hair during the summer?
