Hair ends are smooth
The hair is thick, plentiful and coarse, but just stroking it calms it down!
I saw this product at Cosme Kitchen and tried it out, and it didn't do anything wrong, but when I looked in the mirror later, my hair was shiny, and I was like, "What is this!?" I bought it to go with my beauty day. My hair is coarser and thicker than most people's, so I chose the hard type, and I'm so glad I did! It stimulates my scalp just enough, feels great, and makes my hair shiny, so I feel great in the morning!! I also recommend brushing your hair thoroughly before taking a bath, as it makes the shampoo rinse more smoothly!
It's quite hard. Maybe my hair is too damaged, but I get static electricity.
I like brushes with a firmer stimulation that massages the scalp just right, so I purchased the hard type. Incidentally, I have brushes such as the Mason Pearson Pocket Bristle, the Aveda Paddle Brush, and the Denman Brush. Honestly, I feel like they don't come close to the Mason Pearson when it comes to scalp massage. I think it passes the test when it comes to combing hair, but if you're using it for scalp massage, I highly recommend the Mason Pearson, even though it's more expensive! While paddle brushes are great for a vigorously pressing massage, the Mason Pearson promotes blood circulation in the scalp with every combing, leaving you feeling refreshed. I plan to use the head spa brush as an everyday brush to untangle hair.
