My daughter has very curly hair %26amp; would like it straighter. We have tried a couple of the straightening shampoos %26amp; other products, as well as asked our hairdresser. The only thing that has worked and lasted longer than 30 minutes was hot rollers. Find the biggest rollers you can (1 1/2 - 2 '; diameter at least) %26amp; apply them to your hair while still damp. Sit under a dryer or just keep in until your hair is totally dry. Your hair will be wavy until at least the next day %26amp; even until you wash it again (it may get a bit curlier after sleeping, but it will still be mostly wavy).What kind of straightening shampoo makes your curly hair wavy until it is washed out?
i hav curls hair and i tried it, that shampoo doesnt work well unless u actually straighten or blow dry it, so u probally need 2 apply heat to it but ur better off just straightening it but there is this sraightning cream that i did use, it has one for curls and one for straightning hair, i forget what it's called but it's in a pink bottle..
