Hindi ko sure kung safe during pregnancy or breastfeeding ang keratin treatments kasi may chemicals involved, so mas mabuti talaga na tanungin mo muna ang OB mo bago magpagawa! In the meantime, if you're noticing hair loss or thinning, try Mama's Choice Hair Loss Treatment Shampoo & Conditioner, they're pregnancy-safe and breastfeeding-safe, at nakita ko talaga ang difference sa hair ko after a few weeks. You're being such a thoughtful mom by being careful about what you're exposing yourself and baby to, that's what matters most!
