I have rolled since february and I didn't notice any change involving hair growth so far. Maybe the users that rolled years ago can give you long term information, but I have read hundreds of old posts lately and never saw someone mention hair growth problems.

The oppossite will likely happen due to blood circulation.

Anyway ,if concerned begin as a habit to brush your skin with a dry brush.

Look it up.Of course you have to do it on days that the area is not inflamed by rolling.

Thank you for the feedback

Technically speaking - some people dermaroll their heads to induce hair growth, so I *think* it should be ok.
