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.

Great Hairspray!

I really like this hairspray! The smell is very nice and light. I like the hold that it gives my hair too!

I love a non aerosol spray, it's all I use on my hair. Keeps the frizzies away, at least for me. This spray is quite fantastic. One word of caution, you need to make sure that you have your style "just so" because this will set your hair in place, no regrets. The scent is a bit strong, but overall this is a spray I will use as part of my daily routine.

This is the second product by the NO. 4 brand that I have received to try from Birch Box. I was excited because I loved the first product. I like that this is a non aerosol version and has more natural ingredients in it. It doesn't contain harmful chemicals like most hair spray, and doesn't have that bold smell to it, either. I simply don't use hair spray very often, so I would not purchase this.

I simply love this hairspray! It didn't dry my hair out like most that actually hold your hair will, and the smell....omg amazing!

This is the best hairspray I have ever used-- I was a big fan of aerosols until now-- This keeps hair smooth in humidity and keeps the style in all day! A must have!

Loved this--I have very straight hair but curl it with a curling iron and this did a fabulous job of keeping my curls. It also went on light, wasn't crunchy and didn't smell toxic like many other hair sprays. The only reason I am not giving it 5 stars is that I prefer an aerosol sprayer--the sprayer is hard to keep from concentrating too much of the product in one area.

I always love to get travel size hair products so I was excited to receive this sample. I think as far as a natural type hold goes, it was okay but I just do not like the smell of this product. I prefer more of a clean fresh scent. This smelled more masculine to me.

I love this hairspray! Not only is it safe for the environment, but it works wonders! I curl my hair almost everyday for a beachy wave style and this product helps create the perfect look!

Number 4 Non-Aerosol Hairspray
Sampled

I have already received a few of Number 4 products and I have not been impressed!!! With that being said,
Number Non-Aerosol Hairspray is no different form their other products. I do not feel like it is working well with my hair type. My hair feels dry and frizzy afterwards. I will not be buying any for their products.
