If I remember correctly, the results from this treatment are temporary. The hat-treatment would therefore have to be repeated periodically. Unless a person wants to lose all hair in between treatments the hat would need to somehow stretch patches of skin without pulling out the existing hair.

Darko Savic, you mention very interesting points.
I can't see anything in the study about the treatment being temporary. If that is the case, then the treatment would definitely need to be done regularly. In Chu's study, the mice were made completely hairless (using waxing) before the stretching treatment. [1] Having to be completely bald before each hat treatment would be an inconvenience.

Perhaps the hair regeneration hat could facilitate selective skin stretching somehow. Maybe the head could be divided into different sections. Then the person selects which part of their head they want the stretching to happen. That way, the existing hair won't be pulled out. 🙂
