Unsure.. I own this product and had it on my dresser for a long while now. Maybe it's just me maybe I'm just not using it right or something but it didn't really do much for me. It did however make my hair really shiny and I had a little less frizz but in my opinion it's a little too greasy or oily feeling, it didn't make my hair soft and I didn't like the feeling after it dried on my hair. It did work on my sister's hair though it made blow drying her hair a breeze which usually takes 2 hours because it's so thick and coarse. So its different results on different hair.

A little greasy at times. I use this from time to time, but I find that it can sometimes make my hair look greasy rather than silky and shiny. If I'm having a really frizzy day, it's helpful. I prefer leave-in creams to this. The smell is nice though!

Silky I use this everyday after flat ironing my hair. This leave your hair soft and silky

great product yet pricey

I have the lite bottle, and I must say the best serum I've used yet. I'm not into serum that much, because of how greasy it is, but when I flat iron my hair using this product it doesn't frizz, and my hair is movable (meaning it has body, when I shake my head).

Smells awesome. But didn't quite work out well for me. Made my hair a little greasy at the roots and also had an allergic reaction to it. I'm sure it is a great product for others though. Different strokes for different folks .
