L'Oreal Elvive Triple Resist Reinforcing Treatment.
I've tried a root spray before (the John Freida Collection Root Awakening Strength Boosting Leave-In Spray - pic on my dailybooth here). and this spray was something that I just loved! It was the first root spray I'd tried so don't have anything to compare it to, so it was an obvious choice to pick up this spray for free.
The 'triple resist' claims to reinforce and nourish hair while making it feel stronger. It also says that the root spray is for fragile hair with a tendancy to fall, which I deemed a perfect way to describe my hair atm.
This spray really intrigued me because it says you can use it on wet or dry hair up to twice a day. The weird thing about this compared to the John Freida version was that it didn't say to comb it through afterwards. I did this anyway, as I thought the product would start to build up on the roots.
How I prefer to use the root spray is as part of my blowdry. I section my hair and spray the roots, massage the formula into my scalp and then comb the excess product through the hair, add heat protector spray (I use this one) and then blow dry as usual.
