Is hair loss shampoo effective?

TS Hair Loss Shampoo is said to be famous.

Many advertisements are out there, haha. Has anyone seen any effects yet? I'm so curious ㅠㅠ After having a baby, my hair loss is so severe ㅠㅠ Most of the hair falling out in my house is mine.

Cleaning is also a problem ㅠㅠ I want to receive treatment quickly ㅠㅠ

Please recommend a Tamo shampoo.
