I don’t follow Tati/GlamLifeGuru. Her content never appealed to me, but that is neither here nor there. The reality is that most beauty content creators are not qualified to dispense medical advice. I’ve talked about my use and discontinuation/reduction in use of Biotin before, but I make it abundantly clear that I am not a medical professional. I cannot educate you in health-related choices! So – all changes of the supplementary nature should be reviewed with a qualified medical professional even if your BFF or mom endorses the hell out of ’em.
