I have been blessed (or cursed depending on how you see it) with incredibly thick hair which doesn't always have the most glossy shine and let's face it who wants dull hair? 
The most recent product I have been spraying on my hair with such gusto that you would think I was a woman possessed has been Bumble and Bumble Shine On and On Spray.

This light floral spray is non-sticky but a complete dream to helping tame my unruly hair - I find it great for taming fly away hairs and smoothing down any static hairs too without weighing down the hair.
Bumble and Bumble Shine On and On Spray does of course add shine which will be more evident on darker hair and is also wonderful creating a little volume without the need of backcombing - I simply spray on dry hair then I ruffle my roots up with my fingertips...okay the volume doesn't stay put all day but you can easily run your fingertips through again when needed!

If you are looking for something to add a little radiance and sheen to your hair then this is for you especially if you are one to use and abuse heated appliances.
I personally like to gently mist it on straightened hair for a glossy finish and have been known to use it to slick back my hair before tying it up in a top knot or ponytail for a slicked back look.
All in all I'm a huge fan!
