Answer first
Supplements are most likely to help when a diet is lacking something, and they work slowly. A review of vitamins and minerals in hair loss found limited evidence for supplementing people who aren't deficient. Treat Folli-Activ as one part of a routine, give it a few months, and don't expect it to replace a diagnosis.
What helps most
A balanced diet, enough protein, treating deficiencies and managing stress and sleep.
How long
Hair grows slowly, so judge over months, with photos.
Questions
Can I take it with a multivitamin?
Check for doubled ingredients like biotin and ask a pharmacist.
Will it work for alopecia areata?
That needs a doctor's assessment.
