Ay, better to check with your OB about that, mama! Even if organic sounding, hair dyes have chemicals na pwedeng mag-absorb through the scalp, especially during pregnancy when everything is sensitive. A few of us moms tried waiting it out lang until after first trimester or just did root touch-ups sa safe distance from scalp, pero depende talaga sa doc's advice, bawat pregnancy different, kaya mas safe na mag-consult muna bago mag-color.
