Natural FORMULAKeratin Intense Hair Serum - 4.8 fl.oz - Sodium Chloride Salt-Free Keratin Hair Serum - Hair Repair Treatment For Frizz Free Straightened Hair

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.

like all products be carefull not to over due. I put a small amount in my palms with a chunk of hair down, then let more hair down and add a bit more. but don't over grease.. one of the few that I like and I have very dry thick hair

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.

Very good

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.

I was hoping that my hair would be soft and manageable after using these but that was not the case. I couldn't tell that I had used them at all! Don't waste your money

El laciado es más duradero desde aje lo estoy usando, lo utilizo para el secado y también después que terminó como paso final

I LOVE this serum!!! I bought it to help with the frizziness of my hair, and to hopefully add shine. It has done just that! Not only is my hair much smoother and shinier, this serum leaves my hair very soft, and smelling good. I’m going to buy several more bottles and hand them out to other girlfriends!
