Welcome! My hair was a hot mess for years until I discovered flat ironing. For once I could tame my mane and my hubby stopped calling me "Poodle-head."
A few years back I stumbled across this website and decided to stop the ironing and learn to care for my curls. My first step was to learn about the products I was using. Turns out that what I thought was helpful was adding to my frizz and creating more of a mess. Products with silicones were smoothing my curls for a short time but keeping moisture from getting in. I needed moisture badly to undo my heat damage and get my hair healthy. It took a lot of reading and experimenting to find a routine that worked for me.
There is a wealth of information on these boards. Read as much as you can and learn about products. Your first priority will be to get your hair moisturized and healthy. Here is a good link to start with: Start Here!
It can all be overwhelming at first. Don't get discouraged. Keep reading and asking questions. Things will fall into place and you'll see results!
