I recommend Rausch shampoo.

I have an oily scalp, so I've tried a lot of different shampoos.

Rausch Seaweed Shampoo was the most effective.

When you wash your hair, your scalp feels cool and it has good cleansing power.

Other shampoos didn't like them because they made my hair greasy quickly.

This one also had good staying power.

But the portion is a bit small, so it felt like a waste to throw it away haha.

Please pre-shampoo with something else first, and then use this.

Then, even a small amount will lather well.
