Hair - Why does this always happen?

I could be here for a very long time showing all the pictures of all the hair styles and colour I've had in my life time, but that would just take far too long.
I'm sure everyone (Especially you girls!) have been in a position when they just don't know what to do with their hair anymore. I mean at the moment my hair is pretty dull. It's just plain brown with horrible colours coming through where the brown hair dye has faded and the blonde that I use to have there is now showing through again. Oh, and it's got more dead ends then anything!

My current, very boring hair. And I'm ill, which somehow makes it look worse!

Anyway, I have had more hair colours then should be allowed. The very first time I dyed my hair was when I was in year 7 (English school system...) I think that would junior high for all you Americans out there reading my blog! (I think....!) I dyed my hair red. It was nice, but then it faded, as always, and turned to a dull brown colour. Then I did highlights, then low lights, then dyed it all blonde which was a very bad choice as it turned massively ginger(!!!!) I've also had purple hair, black hair with a red fringe and most recently I dyed my hair black and pink, which I loved, until the pink faded out.

Before...

After...

After getting highly fed up of hair dye that doesn't stay in my hair for a matter of washes,I just dyed my hair back to my natural colour (Chocolate brown) which what it is currently like now. BUT, not only the colour is bothering me, but I realised that cutting my hair short really wasn't what I wanted. When I first got my hair cut short (Compared the length it was before!) I really loved it, but now it's just at the awkward stage where it's neither long nor short.

Before I had it cut.

After it was cut.

Now I just realise that I miss my long hair, and I miss it all being one colour without any weird colours starting to appear thanks to a previous colour you may have dyed your hair. Why does it have to cost so much money to have it done nicely? Why can't your hair ever stay the way you want it? It's my hair and I don't want to spend £100 - £150 to have a cut and colour at some fancy hairdressers.

I guess I'm just going to have to stick with dead ends and a mixture of weird and wonderful colours in there!
