Birchbox Breakdown

By definition, a perfect hair day means getting a gorgeous ‘do without spending hours in front of the mirror. Luckily this multitasking styler does it all in one simple step, providing long-lasting volume and greater hair manageability with added softness and shine thanks to the brand’s patented haircare molecules, PBAE and OFPMA. It even blocks UV rays, safeguards color, protects against heat, and works over time to give you smoother, stronger hair. Plus, the formula is safe for all hair types, including color- or chemically-treated strands and it's made without sulfates, silicone, or oil.

How to Use

Apply a nickel-sized amount to damp hair from roots to ends. Comb through, then blow-dry and style as usual.

Amazing for Fine/Thin Hair!!

I have super thin hair and a lot of products grease up my hair. This product was amazing! I applied it once I got out of the shower. It left my hair soft, silky, and light, gave it tons of volume, and even on the next day my hair felt great and it was not greasy at all.

My New Favorite!!
Purchased

I have tried what seems like every product imaginable for my hair. I have curly hair, which is now colored, that I also like to blow dry straight on occasion. Up until now, I've always used individual products depending on the look I want to achieve. Preparing for a recent trip though, I didn't want to take multiple products with me. So, this was AWESOME. It was weightless and left my hair soft while giving my straight hair a nice sheen and keeping my curls super curly when I let it air dry. It's all I've ever wanted in a hair product. My only complaint is that the bottle is so small!

LOVE IT!
Purchased

I LOVE this product. I use this on wet hair (root to tips) after shower, along with some argan oil on my tips. Then I blow dry and style however I want. My style DOES stay longer (the whole next day) and it looks less dirty the next day. More volume... what else can I say. I am a believer.

Great product for my fine hair!
Purchased

This product really helps control my nature curl while wearing my hair straight. I live in the south where the humidty works against you, and this product helps keep my hair straight and manageable without weighing down my fine hair.

Think I love it
Sampled

This has a nice scent and it does keep down frizz while making my hair look better. I’m not sure it’s any better than what I was using before but I actually rather like it. I will probably buy sometime in the future.
