At home, all natural, non-damaging subtle highlights

For blonde highlights:

Do this on a sunny day. If your hair is dishwater blonde or a lighter shade of brown, you can create blonde highlights by treating your hair with lemon juice. Either bottled juice or fresh will work. Wash your hair with your favorite shampoo. Then pour about 1/2 cup of bottled juice or the juice of one or two lemons over your hair. Comb it through to distribute well.

Apply sunblock generously to your skin and go outside. After an hour of sunbathing or puttering in the garden with your hair exposed to the sun, shampoo again and apply conditioner.

Lemon accelerates the effect of sunbleaching. While it doesn’t seem to cause damage, it brightens your hair and leaves you with subtle blond highlights.

For red highlights:

Mix cider vinegar or wine vinegar about 50-50 with water. After shampooing and rinsing well, pour the vinegar over your hair and massage it through the hair. Rinse well and follow with a good conditioner.

Vinegar effectively removes all detergent residue from clean hair. It also brings out the reddish highlights in auburn and brown hair.

Avoid getting either lemon juice or vinegar in your eyes! Lemon juice works best on hair that’s already on the light side; vinegar accentuates reddish highlights in darker hair.
