Hindi ako sure kung safe talaga yun during pregnancy, mama, better check with your OB first kasi may chemicals involved sa rebond process at prone ka mag-faint from the smell. One of my mum friends waited until after she gave birth para mag-rebond, which was safer for her at baby naman. If you're really worried about your hair though, a few of us just did deep conditioning treatments or temporary styles instead habang buntis pa lang, mas stress-free!
