Biotin typically doesn’t thin out shampoos; the watery consistency likely stems from formulation adjustments. Check ingredient solubility and interactions. Collaborate with the formulator to fine-tune the balance, potentially lowering Biotin to 0.35% or 0.25%. Experimentation and reformulation can optimize texture while preserving ingredient benefits.
