Hair care for severe dandruff during the rainy season

My scalp is oily, so I suffer a lot from dandruff during the rainy season.

I've been using TS Bidi shampoo lately and seeing great results. It's a product from the famous company that Lim Young-woong appeared in. I use it once in the morning when I take a shower.

It worked for me, but I'm not sure about others.
