The Aussie 3 minute miracle is pretty damn amazing if you ask me! well for straight hair I think it is. I use it on my curly hair and it probably does work but I just dont really notice the difference although it does have a great smell!
My friend also has curly hair and she is a regular ghd straightner user, these straightners are fantastic they could straighten anything out! But she found even though she used uv protecting spray to stop heat damage she found that her hair was like straw and began to get a lot of split ends and was dry.
So she came and told me and I suggested the 3min miracle and its worked a treat for her! You can really tell its had an effect on her hair, deep conditioning and all that technical talk! But these days her hairs full of life thanks to that!
