I used this shampoo sample one day while I was home just to try it out. I used it together with the conditioner sample. I got a lot of product out of the little sample, which was great.
I have to say I didn't notice much of a difference (volume-wise) in my hair, but I did LOVE the way it made my hair feel afterwards! It was so soft and light. My hair is usually pretty frizzy, but after using this product, it felt like I had just gotten my hair washed at the salon!
The only down-side to this product is the smell. It's definitely...interesting. I didn't like it at first, but after a while it didn't bother me too too much. My boyfriend didn't think it was as bad as I first made it out to be. It's a very strong scent, and you can smell it for a good portion of the day after using it. The best way I can describe the smell is a combination of menthol and men's cologne, mixed with a flowery scent.
Overall, if you don't mind the scent, this is definitely a great product!
