I used it ~ I can only say that the effect was not satisfactory ~ My head used to be a little oily ~ I used it the next day, and my head itched as if it had never been washed, and the professional oil control type attached was the same ~ The silk source I used before was not as good as Qing Yang scalp care ~ I don't know if it was hot and sweaty recently, but I'm ambivalent now, so I'm going to use it for a while to observe ~ Upstairs actually said it didn't itch after washing for three days, so I took it.
