Ok so this is not a medical question but I do need help. On Synthroid for a TT. My levels are now just starting to even out and I feel good. My hair, however, is still in rough shape. It's not falling out as much but it still feels very damaged. I'd like to know if anybody who has had these hair issues has had their hair colored (foiled) while it was still in rough shape. I'm not terribly vain but I'd really like to get back to my sunstreaked color before too much grey shows up! Is this something that I should wait on? Thanks
