How do you make your natural hair colour lighter?

This may sound a little strange, but take pure lemon juice, and cover your whole head, or spots you want lighter, and sit outside in the sun for about 20, to 35 minutes. After this, wash your hair out with a quality shampoo and conditioner, wait until it is dry and you should see a big difference. Lemon juice also adds a healthy shine to your hair. Hope this helped
