Birchbox Breakdown

Our Miami-based friends told us that this multitasking styling foam helps their hair look pristine through a summer’s worth of sweltering heat and tropical humidity. Naturally intrigued, we decided to investigate it for ourselves, and we’re pleased to report it works in all climates. The body-boosting formula provides flexible hold and can be used to define curls or fight frizz. Bonus: it also prevents heat and sun damage and extends the life of your color with loads of nourishing botanicals.

How to Use

Dispense a small amount of foam into hands and distribute through damp hair, starting at roots for added volume and working through to ends. Blow-dry or style as usual.

Great shine and volume

The first time I used Number 4 Styling foam I got several compliments on the shine and volume I had to my hair. I could tell as soon as I finished my blow out that this is a different product for me. I love the way my curls held for several days, having a touch up blow out each morning.

One of my top products I have discovered from Birchbox!

I use this product everyday. It has been a lifesaver for my fine straight hair. I apply it near the roots in the areas I want a little more volume before blowdrying. It really gives my hair volume and helps with styling, holding curl, etc. The smell is phenomenal too-I absolutely love it. The travel size I owned originally was less than 2 oz and lasted me about 3-4 months, so this full size bottle will last an extremely long time!

Excellent in extreme humidity

I read the birchbox description of this product, and I was optimistic but still skeptical. I travel frequently to Miami and Puerto Rico. I have fine hair, but it gets super frizzy with even mild humidity. Using this product with a blow dryer guarantees me a frizz proof day. Be careful not to use too much though or it looks like you have dandruff.

Great styling foam - no frizz!

One of my biggest problems has been frizz. This has really worked to keep the frizz down and keep my air nice and shiny and thick looking. I have wavy hair and it helped hold my waves and give my hair shine and bounce. I am sold on the Number 4 brand. Love it!

It worked!

I was very pleased with the sample size. It smelled nice & clean. It worked well enough & held my hair nicely for the better part of 8 hours as long as the wind didn't blow at all. What I absolutely didn't like was how sticky it made my hair & the sticky residue it left on my face & neck until my hair was completely dry. It caused a very minor break out at my hair line all 3 times I tried using it. I will say though that I have incredibly sensitive skin. Also if I used even a drop to much of this product when I brushed out my hair a few hours later even if I had just washed my hair a few hours prior my hair would look dirty, greasy, in the areas that had the excess product. It wasn't as if I applied tons of this product. I have very long hair that reaches my butt & I only used about the size of a quarter to fifty cent piece worth of product so in my opinion not enough to make my hair appear greasy. My curly thick texture haired cousin used & loves this though & she had none of the issues I did.
