Zinc supplements can make existing hair thicker and fuller but do not cure or slow hair loss. Long-term zinc use requires copper supplementation to avoid deficiencies.
The conversation is about whether low vitamin levels can cause hair loss. The consensus is that the user's vitamin levels are normal and unlikely to affect hair loss or the effectiveness of finasteride and minoxidil treatments.
Hair loss theory suggests imbalance between Vitamin D Receptor (VDR) and Androgen Receptor (AR) activation. Proposed treatment includes upregulating VDR, downregulating AR, and improving mitochondrial health.
The user has been using minoxidil 5% twice daily, micro-needling, topical finasteride every other day, and various supplements for 3 months to treat hair loss and has seen positive results. They also mentioned using hair growth tablets, biotin, zinc, and vitamins B and D, but not consistently.
