If there is one product that I absolutely cannot go without, it would be this exact one. I've struggled my entire life - from very young on up into my teen years, and even my early 20's and still now as I just turned 29 in April. However, when using "It's a 10 leave-in conditioner spray," I am not in the least bit exaggerating when I say that it completely changes EVERYTHING in terms of the time it takes to style my hair, the feel, manageability, look and don't even get me started on the smell - hands down my all-time favorite smelling product over the years (I may have even sprayed it on my shirt once or twice, as a stand-in substitute for a quick spritz of perfume.. haha)!! My hair has always, always, always been frustratingly thin, frail and extremely prone to fly-aways - mostly due to a health condition I was diagnosed with at age 12, that caused me to actually lose patches of hair, and even my scalp at one point, prior to beginning treatment (for Hypothyroidism, which if anyone is familiar with, you know exactly what I am referring to, and just how hard it is on your body - your hair being one of them). So, when a stylist offered me a small, sample-size bottle of this, I was very excited to try it, because I had asked her what it was she was using in my hair that smelled so delicious!! Little did I know, that it wouldn't only smell like heaven in a bottle, but it would change the way I do my hair, feel about my hair and so much more - for what seems to be the remainder of my life - haha!! I know it sounds cliché, but it really did change my life in a big and positive way. It instilled a confidence in me that I was lacking up until that point, and everyone knows how far a little confidence can go - it took some of the most fragile, split-end and breakage prone, thin, dull, damaged and fly-away prone hair that you've ever seen - and completely, 100% transformed it by adding instant volume, silk-like softness that has been incomparable to anything that any other product I've tried before or since has been able to do, complete manageability - giving me the freedom for the first time ever - to successfully run my fingers throughout my hair, without tangling or getting stuck, etc. I simply can't say enough about this product, and I hope that each of you has an opportunity to also try it - trust me, it's worth the money, whether your hair is desperately in need of saving (like mine was.. ), or just need a little TLC - you will NOT be disappointed by this product - Good Luck!!
