Manual wooden massage comb for head and scalp

I am in this hair-growing group led by my dearest and favourite biohacker. We started by testing the hair density and things I do not even recall. Then, we moved to the topic of proper hair washing techniques and arrived at ways to massage the scalp. This was one of the tools she asked us to buy and treat ourselves with, and so I did. I have used it since the day I got it, massaging the scalp and also my neck, making such a difference in how my head feels. And, the hair grows (most probably because of many new rituals, including this one). I have recommended it to my friends, who love to use it. A simple 5-minute ritual while reading a book or concentrating on this makes all the difference in the world.
