Notes

There are a few old wives’ tales floating around that eating certain foods can reduce your hair growth. These rumors have never been proven with testing.

Recently, some people have suggested that eating a meat tenderizer called papain or another called bromelain can reduce hair growth. These rumors have no basis in clinical research and should be disregarded.
