oily hair

My bangs have been greasy since last year.

My hair was originally oil-free.

I don't touch it because I think it might be because I touch it with my hands too often.

But even so, it gets greasy after a few hours.

It's not like I sweat a lot on my head, either.

Currently Dr. Groot shampoo (received as a gift),

Head & Shoulders Rinse

Protein essence (apply only to the ends of hair after washing)

I am using it.
