Hi Everyone, I believe it really works and want to do it as my hairs falling a lot , have very dry scalp, it never grows since 3 years its still the same size. As rubbing nails together increases blood flow so is it safe to do it in pregnancy? I heard its not good in pregnancy and may lead to contractions but I wanna do it. Please Let me know if it is safe and have tried in pregnancy too. Thanks all of you.
