I began using the comb regularly once a day with the aim of improving facial tightening in the morning. However, I was surprised to find that my hair loss greatly reduced after two weeks. Now, having used the comb for three months, I estimate that the amount of hair loss has decreased by about 60% compared to before, and I am pleased to see the amount of my hair has returned to the level of 4-5 years ago.
Highly recommend!
