I got this awesome multi-tasking in my Birchbox a few months ago and I'm already on my fourth bottle. I use it literally every day. I comb it through my hair after the shower. My hair is super fine and tangles really easily so I need a good detangler. This one also protects my hair from my daily assault on it with a blowdryer and straightening iron. And it has a nice, not-overpowering scent.
Bumble & Bumble Thickening Shampoo
As I mentioned, I have very fine hair. Read: flat. I feel like I've tried most of the volumizing shampoos on the market, but I had given up on the hope that a shampoo or styling product could do anything for my hair. Then I got this a sample of this little miracle worker with my Sephora order. It actually thickens my hair. I can actually see and feel the difference. I also use the conditioner and hair spray which are also great.
GlamGlow Youth Mud
I got a sample of this in another Sephora order and was doubtful about it. I don't use masks often in general and hadn't used a mud mask since high school (anyone remember this one?), but I was tired/stressed on New Year's Eve and my skin showed it. The description on the package said models use it before runway shows so I gave it a shot. I LOVED the results. My skin looked a hundred times healthier, clearer, and glow-y. I highly recommend!
