What age did you start using conditioner?

My 2 year old daughter’s hair is starting to feel more coarse and less like soft baby hair. Right now we just use baby soap for her whole body and hair but I’m curious when people started using conditioner. Was it at a certain age or when they were able to not get soap in their eyes? Right now she won’t lean her head back for me to rinse the soap so I have to just dump the cup on her head which makes some of the soap run down her face so I’m not sure if it would be smart to use conditioner. Are there baby/toddler conditioners that are more gentle on the eyes? Please help a first time mom out!
