Editor's Tip Editor's Tip

According to Living proof.®, hairstyles are held together by a network of hydrogen bonds that gradually break down over the course of the day—which is why your morning ‘do usually droops by happy hour (without Prime, of course).

Birchbox Breakdown

While “forever” may be an unrealistic prospect for your favorite hairstyle, this genius hair primer from Living proof.® will definitely make it last a whole lot longer. That’s right—a hair primer. Apply it to damp hair before styling, and your ‘do will hold its shape for up to twice as long. Not only that, but the lightweight formula makes your hair more resistant to oil and dirt buildup (so you can go longer between shampoos).

How to Use

On clean, damp hair, apply a generous amount into your strands from root to tip. Use it solo for its cuticle-smoothing and detangling properties (we love it as a frizz-tamer), or wear it under your usual arsenal of styling products—it won’t overburden hair because it’s so light.

It Works!

I never would have tried this had it not come in my box...I was a little skeptical at first thinking it would weight my hair down or make it greasy. (My hair is long and fine.) I put a little bit of the prime in my hair before drying it. It noticed it was a little harder than normal to pull the brush through my hair with this in it. Once I was done drying my hair was definitely smoother than normal, and wherever I brushed the hair, it just sort of stayed that way, much better than it normally would. Then when I woke up the next day, my blowout was about 90% intact, and it typically never lasts more than a single day. I am amazed to say, this stuff works. I love it!

Good Stuff

I live in a big city and have to deal with smog and pollution, not to mention the humidity. My hair gets greasy fast but this product helps, My style stays in place and my hair doesn't get limp or gunky. I really like it!

I have a short straight Inverted bob. I received this as a sample and fell in love. My hair looked fab and the style lasted a few days. I have fine hair and this product kept the fly aways at bay and it for once stayed in place instead of flipping out! Didn't weigh down my hair like most products tend to do, I was shocked, a product that contained the fly aways and kept it bouncy and full... Bravo. Love.

This product is amazing. It helped my wavy hair stay straight longer. Also, my hair still felt and looked great on day 2. It's totally worth the price. I'm hooked!
