One, or two of the first products I tried from my Glossybox was the Sebastian Professional Color Ignite Shampoo and Conditioner. For samples, these have got to be the best trial samples I've ever received. The shampoo alone will give you at least 2-3 washes or more if you have short hair. The smell itself is amazing! The conditioner is alright. I really like that the texture is more like a mousse and just one pump goes a long way. You can definitely get quite a few uses out of the conditioner. The only downfall is the smell.
Regular price for the full product is about $16/$16.50 I believe. Would I purchase it? Probably not. As much as I enjoyed the samples, I already love the shampoo I use now and I barely buy conditioners.
