Apply Number 4 Blow Dry Lotion to wet hair before styling, and follow with hairspray for hold and shine.

Number 4 Hair Care

Birchbox Breakdown

It’s rare to find a hairspray that’s great for our hair and the environment. This non-aerosol mist fits the mold: it’s full of natural botanicals to nourish strands, and it provides the strong yet flexible hold you need to tame flyaways and support updos. Best of all, the earth-friendly formula doesn’t contain any harmful chemicals.

How it Works

Styling resins provide flexible hold and shine while humidity resistance technology reduces frizz, even on the hottest summer days. Heliogenol protects colored and untreated hair against free radical damage. All Number 4 products are vegan and free of gluten, sulfates, and parabens.

How to Use

After styling, spray product 10 to 12 inches away from hair for natural, lasting hold.

This is the BEST non-aerosol hair spray I've ever come across. It smells awesome, doesn't leave my hair sticky and makes my hair look nourished and healthy! Definitely buying the full size and adding to my daily routine.

What a great product to throw in your purse for touch ups throughout the day. Also great to throw in your carry on when flying. Helps keep those braids in place.

I'm honestly not a huge fan of this. I've used it once. My hair is very thick, and it did not hold very well, therefore I haven't used this product very often.

Great sample!
Sampled

I really liked receiving hairspray as a sample, because it's perfect to throw into my purse! This product was great. I don't usually like the way non-aerosols apply to my hair, but this was a really nice even mist, with no big blobs anywhere, and it didn't crust my hair up. It also has a REALLY nice scent! I don't use hairspray much, but the next time I need to buy, I will buy this!

Pros and Cons
Sampled

Pros: It's non-aerosol, so easier to get on planes, better for the earth, no risk of exploding in a hot car, etc.
-It held my hair like magic without making it feel "stiff" like aerosols can do. My hair was soft and didn't look "over-done".
Cons: Well, really just one con. It smells kinda weird. Like it smells like hairspray and they tried to cover that up with a weird perfume. Unlike an aerosol hairspray, the smell doesn't totally go away when it dries. It's not overwhelming but I can smell it when I move my hair around. It's not a terrible smell, not something anyone would call you out on, but I don't like it competing with my nice perfume.
Overall I would probably continue to use it because it works better than aerosol, but I might try other non-aerosol brands first to see if they smell any better.

Hairspray is not my friend
Sampled

I LOVED this company's shampoo and conditioner, so I was really surprised that I wasn't as psyched about the hairspray - but for full disclosure, I really haven't ever found a hairspray I like. While it's awesome that it's not an aerosol and all natural, it felt really chemical-y to me. Stiff and not what I was imagining from natural ingredients.

My hair can be very difficult to manage especially without putting harsh ingredients in it! This product did the job.

I bought the large size based on my experience with the sample received in my February Birchbox. I love the smell and hold, but my hair seems bit stiff.
