Thinking about permently straighten

You can go to a salon and ask for a relaxer. Make sure you have a stylist that has experience relaxing you hair type. There are different relaxers for different textures of hair. The relaxer will just smooth your hair down, you will also need to get a blow dryer and a ceramic flat iron. Try to use heat as little as possible. Your stylist can show you exactly to style your hair with the flat iron and blow dryer.
Hope this helps
