Hi MzCreole, Happy New Year!

In order to better assist in answering your question, do you mean that, you are trying to lay her hair down (as in putting it into a ponytail), or are you trying to let it hang down/out?

Depending on the density, the curl pattern (because you said she has two) you may have to try a different product indeed. She may need a heavier leave-in conditioner, moisturizer, or a mixture of some.

But just post a little more info and I'll see what I can do to answer. Maybe even doing some research for you.
