Nope, I refrained from doing these. Chemicals have to be used for doing these and they do get into the blood stream, so even without being preggy or bf I think it's not advisable to do too much......

Still wandering cos i have refain fr all these since preggy until now..bf for 7mth plus. i think i will go ahead colouring my hair bah..cos now not feeding so frequently then before le. at the most give express for that 1-2 days lor...hehhe
