What should you do if your hair is frizzy and looks burnt because you straightened it too much and you have to straighten it just to get the frizzy burnt look out and you have tried hair products?

Go to a real salon (not the cheap kind) and expect to spend a little money to have a professional do the job. If anyone can fix it, a pro can. Make sure your hair dresser is a "master hair stylist" meaning they know what they are doing and have been doing it for a long time. The only true remedy for this problem is to have a good hair cut and cut off all of the dead and burnt ends.
