Minoxidil prolongs the growth phase of hair, and because hair grows slowly, results take months. In the first 2-8 weeks many people notice extra shedding (the 'dread shed') — paradoxically a sign it's working, as resting hairs are pushed out by new ones. First visible changes (less shedding, fine new hairs) come around 3-4 months, with clearer thickening by 6-12 months.
Consistency matters more than strength: a 5% applied daily and actually kept up beats a higher strength used sporadically. Use monthly photos to judge. If there's no change after 12 months of consistent use, consider adding finasteride (men) or reviewing the cause with a doctor. Gains are maintained only while you keep using it.

FAQ
Is the early shedding from minoxidil normal?
Yes — a burst of shedding in the first weeks often means it's working, as old resting hairs make way for new growth. It usually settles within a few weeks; keep going.
Foam or liquid — which works faster?
Both contain the same drug and work at the same pace. The foam avoids propylene glycol so it's gentler; pick whichever you'll use consistently.
