Number 4™ Styling Foam

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.

Love it
Purchased

I love this and several other No. 4 products. I purchased this product, the Super Comb Prep & Protect, Volumizing Shampoo and Volumizing Conditioner soon after trying Number 4 products in my Birchbox. They are my favorite products which I use everyday. I will continue buying and would recommend to anyone!

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!
Purchased

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
Purchased

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.

On the fence...
Purchased

I have loved all the No. 4 products I've sampled in my boxes, so I thought I'd order this in hopes it would give my straight hair some oooomph. It sorta works - not as good as some other products I currently use. The pros are the glorious smell and how soft my hair is when I do use it. It does create a wee bit of volume but not enough for me to purchase again.

Great hold
Purchased

This is a great styling foam. It has a soft, flexible hold with a very small amount of product used. And it has a great light fragrance.

Great mousse
Purchased

This stuff is great for giving your hair a nice root life and body - just make sure to use it on damp or almost dry hair so it doesn't get to sticky or tacky. I prefer to use it on damp hair and comb it into place and let it air dry - you get natural body, texture and hold this way.

Wonderful smell, very flexible.
Purchased

I had been using off the shelf mousse, which worked but gave me helmet hair. This styling foam leaves no residue and keeps my hair from turning into a dandelion all day long. Plus it smells SO good. Will definitely be buying again.

Another Great Number 4 Product

I have just started using Number 4 hair products but had not tried this one. I have fine hair and a lot of products just weigh my hair done too much. This was not heavy at all and I liked how it worked on my hair. I would recommend this to anyone with fine hair.

Great styling foam - no frizz!
Purchased

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!
