Oh hair my hair

I dye my hair, since I am 18. I used to have it naturally light blonde but as I got older my hair tended to get a little darker. I went form blonde platinum to black and red several times. I always had short hair which was better for their condition but since a year or so I try to grow it out (slowly but surely) and don't want to damage any longer my hair. I used different "at home" haircolor and the best I could say now is Clairol Essence and Naturtint (which is one of the safest hair coloration on the market). I have now auburn hair and really like it ;-D
