Over the years I've heard people swear that microneedling helps regrow hair. If scalp tension really is a cause (doubt it is the only cause), perhaps the punctures created by microneedling alleviate the tension. For those who are losing hair due to other causes, microneedling wouldn't help and would lead those researching microneedling to get inconclusive results on effectiveness as the root cause wasn't accounted for.
