Saw Palmetto in Shampoo interfere with Propecia?

[awakeodin]

I'm curious if it does,

I think some people take both SP and Propecia together without issues, but I'm not sure if there's a clash/interaction between the two...

There'd only be a VERY small amount of Saw Palmetto absorbed into the scalp, but I was curious if anyone using shampoo/conditioner's containing Saw Palmetto (Regenpure, etc.) have had any issue's while also on finasteride/propecia?

Thanks : )
