Ever since I had my second child, I've been losing a lot of hair ㅠ

I don't usually have thin hair, but I've been losing hair steadily since childbirth. The front hairline also looks sparse, so I'm using anti-hair loss shampoo and taking one biotin pill a day.

It feels like it might be less coming out, or maybe it's just my feeling.

Please let me know if it really works.. and if there are no health issues even if I continue taking it~~
