I received this product as part of a product package. After trying it, I may never use another hair serum again! Elin Bianco treatment serum completely repaired my dry, damaged hair, and I no longer needed to cut off the four inches I had thought irreparable. I had tried many other serums and deep conditioners prior to Elin, and while they worked, the results didn't last. This Treatment Serum comes in a gorgeous frosted glass bottle, is pastel pink, and smells of baby powder. My hair is so shiny and smooth, and falls nicely whether straightened, curled, or natural. My hair is frizz free when I use it, and I've noticed less split ends and healthier hair in general, even on days I don't use the serum. My hair is long, thick, and naturally wavy.
