Take care of your scalp with a smart brush.

Having one good brush seems to last a long time.

It's a Daiso brush that doesn't break or tear.

Wet your scalp with lukewarm water, mix the shampoo well, apply it, and lather.

Then, gently rub and sweep with a brush.

I've been using this 1,000 won one for a long time. It cleans my scalp well and gives me a massage too, haha.
