it is safe.

BUT if you dont feel "right" getting it done. then dont. Or atleast wait till the 2nd trimester.

If YOU believe that the last hair dye did something to encourage along the last m/c then wait.. ugly hair is worth the miracle you get at the end.

I waited the 40 weeks.. 43 actually to get my hair done. Problem is... i wanted to put a blonde through it (i dont like my blonde colour lol) and i was more worried about it going green as hormones in pregnancy, for some reason unknown, can play havic on what colour your hair turns out.

im blabbering.. lol
