Some people find that Finasteride causes shedding more quickly in the first couple of months.
This is actually a positive sign. It shows that Finasteride is starting to work. The older, damaged hairs are making way for new, stronger strands.
You won’t see any noticeable improvements initially. After six months you should find that the hair is starting to grow back more quickly. It should be thicker and stronger in appearance and the rate at which hair falls out should be reduced.
Basically, don’t worry if you experience shedding early on. This is normal and should stop after a few months of using Finasteride.
