Sun-In with Lemon, Spray-In Hair Lightener, 4.7 Ounce (Pack of 6)

I've used it on my jet black hair and it worked, lightening it slightly. I've used it since my teens and it has maintained the same results. The only difference now is that it is more moisturizing with a better scent. I would recommend it to anyone, but keep the patience because it could take more time for darker hair. On the bottle they don't mention changes on black hair, so they can't be liable for any promises to black haired people.

My husband uses it all year

Use every morning. I don't use a blow dryer, so my hair lightens by the sun and it is a great change. I am blonde again! No residue, no long lasting odor. Great product!!

Got a convertible to help with the midlife crisis. Not enough. Got the Sun In. Now I'm one hot BLOND mama!! Bought 6 more bottles of it. Got REALLY blond. Starting pouring it on my hair after shampooing and leaving it in. Maybe not the best move ... portions of my hair, especially in the back, got frizzled and crinkly. So I got it cut off and started using it according to the directions. Moral of the story: I'm STILL one hot BLOND mama!

It'll lighten dirty blond hair really like if you use enough. It also works well on thin hair rather than the carpets some people have on their noggin. Nonetheless... it's probably not the healthiest stuff to apply to your hair, but if you want to be as handsom as me and my golden locks, give it a shot.
