I have blonde hair with fairly dry ends so it doesn’t generally have much shine so I decided to try ghd final shine spray… and like all ghd products.. loved it! :)
My hair looked not only shinier but instantly healthier! And the shine lasted all day!
Just spray on dry, styled hair.

The only down side is that being ghd it is rather expensive (for my budget anyway), It retails for R180 for a 30ml bottle.
I use mine on weekends only so it should last quite a few months at least.
