Here are the 6 essential things you need to know about clip in hair extensions:

1. Perfect for adding more length and thickness to your hair.
2. Your hair will have more volume (sometimes as much as 100%).
3. Not very expensive and you can buy them on the internet.
4. Easy to apply. However for a more stylish look, I recommend going to a professional beauty salon (we'll discuss this in detail below).
5. Effortless maintenance.
6. Can be changed to fit your natural hair look, color and style.

If you were new to clip in hair extensions the points above should allow you to understand the basics of extensions and help you decide whether you need them or not.
