|Do||Color hair in a well-ventilated area, as the fumes may cause dizziness, nausea or headaches. Step outside for some fresh air if symptoms arise.|
|Don't||Color hair in your first trimester. Although hair dye has not been shown in studies to harm the fetus, it’s best to wait until after your 12th week.|
|Do||Try highlights or pregnancy-safe hair color, such as henna or Advanced Cosmetic Technologies Permanent Hair Color ($30).|
|Don't||Chemically straighten your hair during pregnancy. The strong chemicals used for this treatment are applied too close to the scalp.|
|Try: Safe suds
The chemical-free shampoo and conditioner from Nine Naturals Oh Baby! ($18 each) do not contain parabens, phthalates or harsh foaming agents. Instead, natural aloe and wheat proteins moisturize and strengthen hair.
