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.
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.5
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!5
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.5
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!5
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.3
Finally a mousse that tames my frizzy curly hair, leaves it soft and not as hard and crunchy as other mousses. Smells nice and soft. Great buy!5
I've been using this product in a slightly different way than advertised but its been performing so well that I had to write a review! I start by towel drying my hair in the evening, applying detangler, applying the Number 4 Styling Foam, and letting my hair mostly air dry. When I curl my hair the next morning, I can tell the foam has totally helped to create this nice volume/bounce in my curls. I go one day without washing my hair and oh my goodness, the volume in day 2 is AMAZING! I've never seen my hair with such volume without using hairspray. But this is all sans hairspray now. I love it!! Totally will be repurchasing !! :)5
I went off all the other good reviews. When I got this, it is very liquidy, not foamy at all. Also, it makes my hair dry and frizzy when straight and curly. It also leaves a weird texture feel to my hair. I will not be repurchasing this again. I am even thinking of throwing it out, but it is so expensive I hate to waste the product.1
NO MORE CRUNCH! I have always hated that crispy feeling that mousse or gel turns your hair into. I want my curls to stay all day, but that doesn't necessarily mean I don't want them to move all day! This smells great, and actually really does provide for a flexible hold. I have very fine hair so it honestly doesn't take much! I love No. 4 products to begin with, but this is almost like a leave-in conditioner + flexible hold - if you want to brush your hair out after having this product in, go for it, doesn't break your strands and your hair does feel surprisingly soft even after having mousse in all day. It is definitely pricey and does not last as long as I would hope, which is why I rated it 4 stars, but definitely give it a shot if you experience the same frustrations!4
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!4
