Help!

Hi, I'm new to the forums here and I have a problem who someone can hopefully help me...

Anyways,
Naturally I'm a very light blonde hair color. I've always had long-ish hair since i was little, and ive cut it really short but only afew times and it's always grown back nicely. But afew years back (I'm 16) when i was like 13 - i completely cut my hair really shoirt after having it long (past m y shoulders) I cut it short as in short rnough to have it spikey. Anyways ever since then untill August of 2004 I kept on cutting my hair like that with an electric razor. In august I started growing back my hair because I want it long again. Anyways as it has been growing (pretty fast actually) I noticed that its a much much darker blonde color it was before. It looks like a dirty blonde - maybe a tiny bit lighter than it. Anyways my hair has always been very very light blonde - Maybe it's because i always went to the beach and took in allot of sun but when i cut my hair i havent gone out int he sun much since then- very very little infact. I'm not sure if its that or not but my hair is much darker now and I want to get it back to it's original light blonde  without using any bleach or dye or anything un natural. I heard using lemona nd going to the sun works and i went last weekend for afew hours with lemon sprayed on my haiur and i did notice it got a bit lighter. Anyways my question is how would i go about getting it back to its original light blonde color again?

(Sorry for such a looong post)

Thanks allot for the info.
Yeah I was thinking of waiting it out and growing it and just keep going to the beach and soaking up sunw ithout putting anything on my hair since summer is coming. Another thing is I have always had darker roots for some reason, my roots are like a goldish dirty blonde - even when i had my hair really light blonde and I've never colored it.
So I think for a while ill keep going to the sun without lemon juice and see how it goes hopefully it lightens.
Thanks allot :D
(By the way how long would i have to sit int he sun? afew hours or so?)

Ah so it does? I kinda thought so...
Still though can it still lighten to a light blonde color like before by going out int he sun? or is it a lost cause?
Thanks for the help!

Alright, I don't plan on using sun in, if anythign if it doesent work - i'll go fo rthe lemon juice.
Thanks.

puberty does that.  when I was little I had the lightest blonde hair, now I have a dark brown.

Some people just have natural highlights without sunning.

I'm also considering buying one of those herbal Shampoos that bring out the lightness on my blonde hair, can anyone tell me a good one for blonde hair that can bring back natrural lightness and so on?
Thanks allot -
(PS : I found this one I wouldn't really know if its good or not Frederic Fekkai Baby Blonde Shampoo - and I also found an aveda one fore blondes)

They say those shampoos bring out highlights, for blondes they often have marigold or chamomile or something in it.  I personally never noticed much difference when I was natural blonde and I used them, but that was 20 years ago so maybe the newer ones would do something.  You may just have to try them and see.
