Three reasons I can think of for why your child's hair may still be poofing:

*It does matter what kind of conditioner you use. Some can be too light, and some can get crunchy or sticky or build up in your hair. I've had the best results with the conditioners I mention on the site. If the conditioner is too light, it just evaporates like it was never there, instead of doing the job you need it to do.

*You might not be using enough of the right kind of conditioner. I really slather the conditioner into my hair. When you are combing in the conditioner, it will foam up if you are using enough of it to do the job. By the time you are done, and finish defining your curls, it vanishes. On the rare occasions it doesn't, just dab a little water on those spots and wipe it away.

*For the conditioner to set and and keep her curls nicely clumped, her curls need to be defined when they are very wet and with the conditioner in them. You can define her hair either by running your fingers through it a few times to release her curls (if her curls are loose enough—my curls won't let me do this option), or you can take each little curl and twirl each one around your fingers (if she has tighter curls), or you can take each curl you see wanting to form, and smooth each one between your fingers by running your hand down it (the method I use).

At night, after her hair is dry, you can bun or braid up her hair. This also helps to "relax" her curls. In the morning just smooth a little conditioner and water over her fuzzies and ends to refresh them, and you are done!

Conditioner is the only product I've been using in my hair for about 12 years now, so it does work. And I say, why spend the money on extra products if we don't need to?
