Functional shampoo for hair loss relief

I understand that there are separate medicinal hair loss shampoos, and that shampoos sold on the market are classified as cosmetics, not medicines.

As a result, people say it is practically ineffective, and I don't really feel much of a difference. I've tried various other products besides this one, and it was the same. It is much more effective to use a mild shampoo while massaging your scalp and taking oral hair loss medication.

It was refreshing, but it stung a little at first. Other than that, it was fine.
