Great for fine hair

The smell of the spray I really enjoy because it's pretty lightweight but smells kinda earthy. I think it's an acquired smell, but I personally enjoy.

Some of the ingredients are not my favorite nonetheless still a decent leave in. [I received this product in exchange for my honest review]

I received this product in exchange for my honest review. My hair can be kind of finicky where it will really like a product for a couple days and then hate it. Sadly that's what happened here. After the first few uses it was too heavy for my hair not matter how little I used.

[I received this product in exchange for my honest review] Biolage Full Rescue Densifying Leave-In has the classic Biolage smell. It helped detangle my wet hair to be combed before drying. My hair felt soft after using, but it didn't leave my hair feeling as smooth as I hoped and I didn't notice much difference in thickness. I wish it had heat protection because without it I am unlikely to reach for it very often because I don't want to have to apply multiple products.
Will repurchase its that good!
