How long does it take for FPHL to progress?

FPHL can affect women in any age group but it occurs more commonly after menopause. The hair loss process is not constant and usually occurs in fits and bursts. It is not uncommon to have accelerated phases of hair loss for 3-6 months, followed by periods of stability lasting 6-18 months. Without medication, it tends to progress in severity over the next few decades of life.
