DD is 18 months old and doesn't have much hair, but the hair she has is about 2 inch long at the back and sides. My problem is it is so fluffy every morning I have to wet it again before we can leave the house. I tried a little bit of coconut oil, but it stayed oily. I am currently using a tiny bit of my own conditioner (it's QV) and it helps a bit. I have also noticed there is only 2 in 1 shampoos for toddlers, not separates.
Is it ok to use my own conditioner? What else could I use?

TIA
