scalp brush

It is a product whose name I don't know very well.

It seems like I bought this a while ago; it was buried somewhere, but I found it recently and am using it again.

It is a scalp brush that cools the scalp.

I didn't think it would be anything special, but after using it, it feels so refreshing.

It stimulates the scalp without putting strain on it, and it was smart.

It feels refreshing and cool to comb your hair when you are tired at night.
