How many times a day do you wash your scalp with shampoo during summer?

I definitely washed my hair with shampoo in the morning, but by the afternoon it looks greasy, right?

I'm 고민 whether I should change my shampoo or if I should be more thorough with my shampooing method.

You should wash your hair with shampoo about twice a day in summer.

In summer, we do it twice a day, in the morning and evening.

In other seasons, I shampoo once a day at night.

I usually wash my hair carefully to prevent hair loss, but during summer, I'm worried about how to take care of my scalp to help prevent hair loss.
