What do I do with all this Hair?

This is a picture of a now 15 year old who  has  African/Asian hair. So curly and now we have cut it short but still pretty bushy.

Now a 12 year old who has this big, big bushy African/Asian hair that is so thick and dense.

The problem is, I haven't found any shampoo or hair product suitable for them here, in Malaysia.  Asian hair is mostly straight and soft.  Help!  I've seen some hair products to tame these hair but they are not available her. Sigh
