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
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.4
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.5
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.4
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.5
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.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
This product was made for summer. If you don't live with humidity and or dry hair, please keep that to yourself! The mouse is not drying, and easy to distribute. My hair held its shape post blow dry in a humid beach environment. I liked the fact that my hair felt healthy and flexible and just looked good. I have repurchased it (don't want to run out), and was glad that a small travel size came in one of the sets. I will use this year round because the mouse just made my hair feel like hair should!5
