I would say, it depends on the user, but it is very likely that it will cause some excess shedding.
When I run SD I had the worse hair shedding ever after 2 months, and it lasted for at least 3 months. I was terrified.
When I used epi I had some mild hair shedding, but nothing noticeable by others.
If this is the case for you , you cannot do anything to prevent it, your hair follicles will get on telogen state while you are on cycle, and after 1-2 months you will shed those hairs.
In any case, any hair you ll lose, will grow back again.
