To Dye or Not to Dye?

For answers to your biggest hair-care questions, we turned to OB-GYN Chrysten Cunningham, D.O.

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.
