Does Saw Palmetto Cause Hair Shedding?

[Marshmalo]

yes it does cause shedding. Anything that afffects androgen balance will cause shedding.

some say sheds are "good" and that it means the treatment is working
I say sheds are "very bad", you are already shedding with MPB why would you want to shed more? does it not make sense to reduce the shed rather than increase the shed?

I think that's a somewhat short sighted view, shedding during the initial stages of treatment is considered a good sign as it supposedly means the hair root is out of its resting phase and is being pushed out by a new, healthier hair follicle.

I don't know whether it's true but that's a brief explanation of why shedding is a good sign at first and answers your question.
