If you wash your hair with curly hair shampoo, will it make your hair curly?

Well, my Mum has really curly hair but i don't and i desperately want it. When i get out of the shower my hair is curly and if i don't brush it it stays curly. But if i brush it it goes straight again. I am wondering if i wash it with herbal essences 'tousle me softly' it will go (and stay) curly, and if i use their moose too. Any ideas? thanks(:
