Is it advisable to use a conditioner for a baby?

Like Hui Qun, I personally wouldn't use any conditioner for my baby because he's too young. His California Baby Calendula 2in1 Shampoo & Body wash would be sufficient for now. However, like what Hui Qun said, my elder girl has been using the conditioner ever since she has started primary school and she loves it! California Baby products are on the pricier side so I would normally stock up during baby fairs
