I think it’s best to opt for organic or safe hair colours. Hair dye and bleaches smell, and if you're breastfeeding, your baby is inches away from you so that may be harmful to him/her.
Cellowax gamitin mi sis. Safe para kay baby di sya tulad ng ibang pangkulay na malalanghap ni baby.
Ok lan naman kaso matapang yung amoy ng mga pangkulay e. Mas ok ata bleach wala amoy
