I started using this spray 3 weeks ago and I am quite impressed with the results. I use it once every 3 days on towel-dried hair, brush it through with a wide tooth comb, and then blow dry to intensify the result (as recommended on bottle).

After 2 uses, people noticed that my hair was lighter.

I am currently growing out my blonde highlights and trying to get back to my natural colour (ash blonde). This spray has not made my hair super platinum blonde, but it has helped to disguise the difference between my roots and highlights.

I only use the spray on my roots, so I am not too sure if it does damage the ends.

Pros:
Easy to use (spray bottle)
Nice smell
Makes hair look naturally blonder
Awesome price (R40 a bottle)
Bottle should last quite a while as not much is used

Cons:
Not a very dramatic effect (if that is what you are going for)
Spray can damage clothes so wear old towel around your shoulders

I would buy this again as I like a more natural look, and it is an easy, cheap alternative to highlighting my hair.
