Everyone wants their hair to look nice. But using heat products everyday can ruin your hair and then you'll just worry about it even more. Try and limit yourself to 3 heat product uses a week. And washing your hair. Its good to wash it about every 3 days or so. Like heat products washing excessively can ruin your hair too, making it look greasy. Once again you'll be worrying about it. Hair coloring, your natural hair color is not going to green or blue - so whats the problem??! Dying can ruin your hair and you may have a reaction. Dying it in the first place is OK, but bleaching - in my opinion - is out of hand. I think you can probably see my point by now.
Trying to make your hair nicer than it already is can often ruin your hair. Please be happy with yourself the way you are. You are beautiful and you know it, now you just gotta show it.
