Hair Dye Disaster

I felt the need for a change and decided it was time to dye my hair, nothing drastic just to make the colour more lighter and o my god what a disaster!!! It all started off so well and ended so wrong! I have dyed my hair several times before but every time i go for a different make this time i went for Wella, a very summery colour that should of turned out light brown. I went along with all the directions on the box and made sure i applied it evenly throughout my hair after 20 minutes of torture, the smell is repulsive, i washed the dye off and dried my hair. I was shocked to see the end result, in some places it was light and other places dark in large circles. The worst was having to step out in public to get to my hairdressers FAST for advice and a re-dye. Anyone who is going to use this hair dye be very careful and do not be surprised if it turns out to be a disaster, you have been warned!
