it will very very gradualy but also is slightly conditioning

spray or dip in

then

go out in the sun

repeart

or

use a blow dryer

it takes many applications to lighten them but they will lighten gradualy and safely

thanks so i dont rinse it out after i go in the sun?

ive used lemon juice mixed with water before and i noticed the baby hairs around my hairline (super fine hairs) got a lot lighter. they went from dark brown to blond. i noticed no change on the rest of my hair, but i only did it a few times. I didn't go out in the sun. my hair is dark ashy brown with a blond sheen in the sun light.
