Is it advisable to use a conditioner for a baby?

Hey! Usage of conditioner depends upon the age of your baby. If your baby is under 3 years it is not really recommended to use conditioner. You can use nourishing conditioner only as per need after that. To deal with hair knots you can try spray detangler. At times it is also mentioned on adult shampoos / conditioners if they are safe for kids and at what age.
