Query: Nice product

The smell is great, very light, not overwhelming.As for the serum itself, it is really thick, so use sparingly, and don't bother using if you have thin hair. I have very thick, wavy hair and I use after I blow dry my hair. I don't use near my roots and concentrate on the ends. Unfortunately, if you touch your hair a lot, you can feel the product on your hands. But if you have thick hair and want shiny, straight hair in hot, humid weather (and not break the bank), this is a great product, just use sparingly and don't play with your hair.
