Initial paradoxical shedding — a slight increase in hair fall in the first 2-8 weeks

Important note — Initial Shedding: An increase in hair fall in the first 2-8 weeks is completely normal — follicles are shifting into the growth phase. This is not treatment failure. Do not stop. It should begin to improve after 8 weeks.

These side effects are usually mild. If they persist, inform your doctor.
