I'm curious about hair loss prevention.

Lately, my hair has been getting thinner and the amount of hair falling out is gradually increasing, which is concerning.

Is it because my scalp got worse due to the hot summer sun and UV rays?ㅠㅠ

I see you are taking a lot of biotin and collagen supplements~~

Are massages for preventing hair loss helpful?

I dye my hair frequently, so I'm really 고민입니다ㅜㅜ
