Revelation! I hadn't thought about under active thyroid and it affecting your hair but I've got that as well! Thank you, Sunfield, for making the connection and your recommendations. No wonder I'm struggling. I think the message is, do the best I can in whatever way I can with the hair - I already use volumisers etc but maybe add more with pieces, rollers, just 'do it with smoke and mirrors'!
As for the teeth, I cannot come to terms with this gap and the soreness at the moment, I'm missing a whole side of my mouth for eating, cleaning my teeth and so on. I'll just have to manage and again, make the best of it. It doesn't inspire me to smile, put it that way. My silly H has agreed for us to go out tomorrow night, I'm not ready to go out, talking to people so I'm going to have to keep my mouth shut (if I can) as I can't refuse to go. You are all so kind.
