I have naturally straight hair with a slight wave to it that doesn't seem to want to hold a curl. The only few times my hair did hold a curl was when someone did it for me with a wand, those curls held for 2 days. I don't know what hair products she used though. I recently bought a Tymo automatic hair curler, when I used it the curls did turn out good but I had put some mouse in my hair and a lot of hair spray and the curls still didn't quite hold all day. Are there any tips you could give me on what products I should use or advice on what I could try differently to make the curls last longer?
