Concern) Circular hair loss in the middle of the head

Honestly, even if I have hair loss, I don't really care if it's not visible to the eye.

Every time people see my crown, and

Every time I go to the beauty salon

It is said that a bump has appeared on the head.

I knew about it, but hearing it repeatedly still feels unpleasant 😥

At the beauty salon, they tell you to part your hair in the opposite direction, but that's not so easy either.

Moreover, why is my hair shedding so much despite using shampoo... Since it's summer, I was growing my hair, but if I cut it short again, I think the hair loss will decrease.

Can circular hair loss be effectively treated with hair loss shampoo?

Or should I consider a hair transplant?
