SO, I am mixed - both black and Mexican. I have very kinky, curly hair, which I relaxed for years. I started wearing my hair naturally (without chemically straightening it) about two years ago, and I love my curls, but sometimes I like to wear my hair straight, without fearing the loss of my curl pattern from heat damage. When I would find things that worked, it would make my hair hard, crunchy, and sometimes sticky - it would always get really tangled too - not to mention FRIZZ OUT after only 15 minutes of being straight or stepping outside (there isn't a lot of humidity in Sacramento). So finally I set out to look for a serum that would add moisture to my hair, and control the frizz, not to mention PROTECT IT. This product has done wonderful things - like the viewers said, a little goes a long way with this product, so if you don't like your hair to look too shiny - don't put so much in. I've used almost every product for black hair, and trust me, this is not GUNKY, it doesn't leave a residue on your fingers after touching your hair. It makes it very shiny, bouncy, and it smells wonderful. It takes less time to blow dry and straighten my hair with it, and it keeps my hair tangle free until I wash. I'm so glad I've found it - I've only straightened my hair earlier this week, so I'm hoping when I wet my hair my curls will come back to life, I'm sure they will. If you have problems with frizz, I would try this product. If you have natural black hair, and you're looking for a product that will help you easily straighten your hair and leave it silky and smoothe, try this product. I've tried so many, and this one actually does what it says it does.
