Help! I am balding.

At 4 months old my youngest baby's hair started to drop. Before her hair look like someone who just had a chemotherapy, I shaved her head. She is bald now. At the same time, my hair started to drop too! They break easily. I started using the hair loss treatment shampoo to strengthen my hair but I get more dandruff instead. :( Before using the hair loss treatment shampoo, I already have dandruff but they are under control because I am using the anti-dandruff shampoo. Without an anti-dandruff shampoo, the dandruff became more. So now, I am alternating between hair loss treatment shampoo and anti-dandruff shampoo.
