I've been looking for a safe hair multivitamin for a long time, and by safe I mean a pill which will help my hair and not make my stomach mad with burping or my urine turn yellow. I use topicals from Scandinavian Biolabs and quite like them, so I decided to give their tablets a shot. I've had no digestive or urinary issues and growth has definitely improved. Are the bulking and surface treatment agents safe though? Any input would be much appreciated.
