I love the smell of the various Givanni products especially the Tree Tea line but this one is also excellent in smell and results. I have very thin hair so volume shampoos and such are great for my hair. Being that my hair is fine, this product does exactly what I feel it should do...it makes my hair feel full. The only problem that I find with it is the very expensive price for such a small amount so, to combat that, if I am in TJMaxx, I look over the in the beauty department and typically find it there at a lesser price for a larger amount. Both the shampoo and conditioners can be found there. Past that, the product works very well. Effectiveness It gives my hair the lift and fullness that it sometimes needs being that it is thin and fine. Scent Giovanni makes their shampoos and conditioners in scents that I crave and truly look forward to using in a hot shower. I only wish it would last after the drying process... ?
