I bought this because I trusted the Fekkai name, and I had never used a primer before. I was looking for something to protect my colored hair from the daily heat of a blowdry. Perhaps, this is something that takes a while to notice, or it's simply one of those things where it's preventing damage before it happens. Either way, I didn't notice a sleeker blowdry only from this product. I do notice it if I use the Fekkai glossing cream. I will keep this up, though, just to see what happens.
