To the lady who wrote in saying her eyebrows were starting to disappear
etc. I have this problem regularly together with eyelashes disappearing! To reassure her, they grow back usually within a few says. This happens on and off, I have been on Thyroxinee treatment now for a few years. The doctor wasn't really very good on advising me. I hope this helps.
I have not had much of an eyebrow for thirty years! In fact I’ve noticed that my brows are getting even sparser lately. A good eyebrow brush and some brown eye shadow fills in the gaps!
