i bought it based on the rave reviews and the super shine this gives. First, I have grown to LOVE LOVE Kerastase (Architect) line and when I use Fibre Architet, the shine it gave with a small pump is amazing. I bought this because there is more in the bottle (1.7 oz) but the shine factor is not as good. The smell is a strong alcohol smell with a hint of flowers and I don't see that it does anything special to my hair (in terms of health). I would stick to the green line next time or use Gold Lust oil which to me is the best at shine factor (and amount of product). Not their best from K.
