Description
If vitamin b12 for hair is confirmed as a relevant factor, correcting it through diet or supplementation is a meaningful, evidence-supported intervention and combining that nutritional foundation with a consistent scalp-first daily routine addresses both the internal and external contributing factors simultaneously.

While true allergies to methylcobalamin are exceptionally rare, any documented hypersensitivity to vitamin B12 preparations would contraindicate the use of this combination product
