I'll recommend a refreshing cooling shampoo for the rainy season.

Moremo Scalp Shampoo Clear & Cool >

This is a shampoo that cools the scalp down with a refreshing sensation, just like a peppermint candy.

It lathers really well and cleans effectively, so I can wash my hair feeling refreshed.

Even when rubbing the scalp, my fingers go easily between the hair without feeling stiff.

I like that I can shampoo thoroughly.

It's the rainy season these days, so when I forget my umbrella, I end up getting rained on all over my scalp.
I always shampoo with Moremo Shampoo to protect my precious hair.
