AVEDA Light Elements™ Smoothing Fluid, 100ml

Aveda smoothing fluid works really well without leaving a residue on my hair. Some products can turn my white hair yellow, this does not happen with Aveda.

I don't have particularly frizzy hair or anything, but a few drops of this on my shortish bob before drying and straightening are lovely. Easy to manage, soft and shiny, just a tad expensive but it really does last forever!
