Yep, no problems at all. I've continued with my normal appointments every six weeks starting from the 4 week mark. My hair dresser assured me no harm can be done to bubs. He also told me the dye he uses is actually an all natural dye anyway and he also uses it on his pregnant daughter.

Definitely tell your hair dresser your pregnant though as they may opt to use different products and some pregnant woman react to dyes differently during pregnancy too so they may want to factor that in.
