@kidsmomof9 I guess if your incontinence didn't start until recently we can't blame giving birth!
I take 2500 mcg of Biotin, twice a day. I believe that amount was what my transplant team recommended, I always try to follow their recommendations.
The transplant dermatologist I go to has said that anything over 30 SPF is a waste, and if it costs more to not bother! I have seen this mentioned in other writings also. If it's not more costly of course, it can't hurt.
I don't know anything about autoimmune conditions but it must be troublesome to have it widespread in your family. So far, we have not had any of those situations.
