I wouldn't do it while pg Naetha. It's probably fine but just to be on the safe side. If you google it there's lots of scare stories about how it contains formaldehyde which is v toxic but the new formulations are all formaldehyde free and meant to be pretty gentle....still I wouldn't risk it while pg.
You can do it on coloured hair though.
I know, the pic in that article wasn't the greatest advert but I've seen other pics which are good. Apparently the model Giselle swears by it and I think she's got gorgeous hair (and everything else ).
I think the idea isn't to make hair poker straight (like Yuko does). It just makes it smooth and manageable and frizz free like after a good blow dry.
Apparently the more damaged and porous and frizzy your hair is, the better it works....which means it should work really well on me
My hair's not super curly, it's just wavy with a few random ringlets underneath. But it is really frizzy and prone to puffing up and looking a bit wild and bushy. Not a good look. When I blow dry it myself it seems to make it even worse.
I do feel guilty about the cost (won't tell DP ) but it's true that lots of women spend that kind of money on highlights on a regular basis....that's what I keep telling myself anyway.
Anyway, appointment at 12.15. I'll report back this afternoon!
