I recommend Ryeo shampoo.

I bought this because I heard it was good for hair loss, and while I'm not sure about the effects yet, my hair quality has definitely improved.

My hair is extremely curly, so even when I get a straightening treatment, it starts getting frizzy again after a short while. However, since using this shampoo, the frizzing has definitely decreased.

Since it is an herbal shampoo, the scent is a bit strong, but I think it is a good product, so I recommend it!
