How painful is a hair loss procedure?

As summer approaches, my scalp frequently feels hot due to strong UV rays, and my hair seems to be thinning noticeably and falling out easily, so I am planning to get intensive care.

 

I feel that home care involving only changing shampoos has limitations in fundamentally improving the scalp barrier, so I am becoming interested in treatments that directly supply nutrients.

 

To receive an effective hair loss treatment program before it is too late

I want to take this opportunity to get a real, proper consultation!

 

Actually, I'm really scared of the pain...

For those who have received hair loss treatments, how painful is it?

 

And considering the hair cycle

I would also like to know the recommended frequency for visits to manage hair loss treatments for optimal results.
