I have been taking prednisone for almost a year and do not know when I will be able to discontinue it. I am 44 years old (female) and my normal thick red hair is thinning dramatically. Are there any supplements that will slow the thinning process down?

Steroids have the effect of thinning out the hair. I do not know of anything that you can take to minimize the impact of the prednisone, but you should still get your hair mapped out for miniaturization and get a diagnosis. Although the prednisone may be the cause of the hair thinning, you still may have other problems and a good medical evaluation would be indicated.
