This product goes on so smoothly and weightlessly that I can't even feel the product except that my hair seems stronger and a bit softer and smoother. Since my hair is dry, coarse, and super thick so on its own it isn't enough to smooth my hair, but I can combine it with other serums and oils. One benefit of it being so lightweight and being able to use it dry is that I can through it on right before leaving the house for the UVA/UVB filter (which is important even if you don't colour your hair!) and not have to worry about buildup. I can't attest yet to whether or not it lives up to its colour-preservation claims, but it does make my hair stronger and smoother and does seem to preserve the colour at least a bit, and it adds shine. The scent is hard for me to describe, but it definitely smells "natural" and warm (in a summery way), like the fluid itself, the scent is light and shouldn't conflict with perfume. Definitely love it and recommend it. It should work nicely on all hair types.
