PRP (Platelet Rich Plasma) and GFC (Growth Factor Concentrate) have become two of the most popular non-surgical options for early hair loss. Both use concentrated growth factors from your own blood — there's no foreign substance involved.
The right candidate is someone with early to moderate androgenetic alopecia, where there are still visible miniaturised hairs that can be reactivated. People with completely bald patches will not benefit from these alone.
A typical course is 4-6 sessions, one month apart, followed by maintenance every 3-4 months. The best outcomes come when these are combined with medical therapy and a proper scalp routine.
