Anyone know of a product that straightens natural black hair and it's not a perm. It comes in a 12oz bottle?

I saw this product in an ad a while ago and it stated it was the perfect option for women of color who want to straighten their hair without a perm. It was either a liquid, lotion or shampoo.Anyone know of a product that straightens natural black hair and it's not a perm. It comes in a 12oz bottle?
Culture: 7 day relaxer....I have some, its a lotion you apply before blow drying. I have natural hair and tried to use it, but was not impressed at all.Anyone know of a product that straightens natural black hair and it's not a perm. It comes in a 12oz bottle?
I know what you're talking about, a lot of people use it for their children's hair to make it manageable. It's some kind of lotion that's applied after you shampoo and you blow dry the hair with a comb attachment or round brush - it will relax the hair a good bit, but you'll still need to flat iron.
Good Lord, I thought this stuff tasted weird
