Silky Smooth
I am very impressed with this product. After first using the recommended Natural Formula shampoo and conditioner, I applied this serum to my hair. I must say that the results were immediate! My hair was soft, shiny, and manageable. I straightened my hair a few hours after applying the serum and the flat iron smoothly glided through my hair. I am looking forward to how long the serum extends the straightening. The bottle says that it extends it by 3 times. Based on my first use, I highly recommend this serum.

Absolutely love the results
I pay for high end salon keratin treatments twice a year. It has made all the difference in my blonde/natural graying fine textured longer hair. I wanted something to refresh the softness and results. These capsules are so easy to use in the shower and yield great results in softness, reduced dry time, etc. I saw they became unavailable. I'm waiting...hoping they come back.

Good Product
It has a nice smell and it is a great final product to add to your hair. I use it wet and on dry hair, my hair is blue so it had lots of chemical bleaching done over the years. It helps with flyaway baby hairs and does not make your hair look grease, at least not mine since I do have dry hair.

Extremely disappointing!
I have been using this for at least 3 years. It was the only thing that helped to tame my frizzy, dry, kinky hair. I loved it and have bought it faithfully. The last bottle I bought was shocking because it was so watered down and is now useless. I'm so disappointed and need to find something else, like what I had gotten used to.
