Are you taking preventive measures for hair loss?

These days, the amount of hair falling out has increased.

I've been worried because my hair has been thinning since a long time agoㅠ

Since it's summer, the scalp is probably affected by UV rays... ㅠ

Currently, there is no special management; I am just using anti-hair loss shampoo and taking biotin.

Will using scalp serum or something like that help improve it... I'm really worried ㅠㅠ
