I am 18, and when I was 4 I suffered a scald to my head and it caused the hair to fall out and it will not grow back, the burn is about 3 or 4 cm on my head but I can cover it up with my hair so its unnoticeable, but I am very bored with my short flat style hair and I want to grow it longer in to a style that has more imagination and fell to it, something like this!

My hair is fine and jet black and I have a longish face and pointed chin, please can you give me some advice so I can once again feel good about my hair and be more confident.

Your hair would be perfect for a Blade or razor cut as it is typically known. The reason for this is that, having your hair razored would increase the amount of varied layers within your style, making your hair appear thicker and much easier to manage. The razoring or feathering would make your hair more malleable and allow you more options while styling. It is also a perfect technique if you need to grow your hair slightly longer as it will help stop it parting and becoming heavy which could result in your scald showing.

The picture of Keanu Reeves is a good image and I think that this may indeed work for you. But please ensure you have texture put into your hair otherwise it will become heavy and problematic.
