Hair type is transient. You're much better choosing ingredients/products by your properties. As you get better with choosing products and techniques, you'll find that your curl pattern gets stronger.

It's all about getting the protein/moisture right. Fine hair generally likes protein. I do at least one PT a week and use a lot of products with protein. I generally use really rich products and don't need to DT.
