I am a big believer in a dry shampoo. As my hair is quite fine it tends to look quite dull very fast and my second day hair looks horrible! So you will understand that for most of my adult life I used to wash my hair EVERY SINGLE DAY! Needles to say it means you have to get up much earlier and since I am not a morning person it made my life so much more complicated. That is until I discovered dry shampoo!!! The best invention since deodorant if you ask me. It is a miracle product, makes you hair instantly fresh and gives much desired volume (that I LOVE). In the last three month I have tried three different dry shampoos and here are my thoughts :).
Klorane
The most expensive of the bunch (around 19 $CAN) works really well. But here is the problem the bottle is finished after 3-4 uses which is absolutely ridiculous after shelling out around 20$!!! My sister has also used this one and had the same problem. I honestly believe its bit of a waste of money.

Fat Hair
Is definately my favourite out of these three. It is around 10$ CAN and does its job quite well. It does have a stronger scent than Klorane but it smells not bad and scent does not linger. I would definately buy this again.

Got2b rockin' it 4ever style stay
The cheapest of three is my least favourite. Its an absolute rubbish!!! It does nothing and smells horrible. Not only it doesnt keep your hair fresh, but makes it look greasier and dirtier! Will NEVER buy this again!
Have you tried dry shampoo? Which one is your favourite?
