Review on Kevin Murphy Thick Again: Enhancing Volume & Thickness Spray, 3.4 Ounce by Susan King

Appears to be genuine. Fast shipping too. *UPDATE* After using this and then going back to what was left in my original bottle from the licensed seller/salon I realized there might be a difference. It's supposed to make your hair thicker, at least it makes it look thicker, and I've used this and the women's version and their version might work a little better. But beware, I'm not saying what I got here at Revain is fake, but it definitely didn't smell that strong (not that it's smelly stuff at all), it seemed to have a slightly runnier consistency, and wasn't that effective. like the ones I bought from a licensed salon. There's a very good chance they can be diluted, perhaps to get more out before shipping.
