Number 4 Hair Care

Birchbox Breakdown

This isn’t your Aunt Edna’s helmet-in-a-can hair spray. This flexible-hold, water-free spray will make your mane will be as high and mighty—or as subtle and sophisticated—as you’d like, while still allowing for natural movement (and no flakes or frizz).

How it Works

Flex-net resins provide flexible hold and shine (and make it easy to brush back into place the next day) while humidity resistance technology reduces frizz. The brand’s Liquid Complex Culture ™ protects from thermal styling and UV rays, preserves color, hydrates, and strengthens. All Number 4 products are 100 percent vegan and free of harsh stuff like sulfate and sodium chloride, gluten, and parabens.

How to Use

Hold the can evenly about 10–12 inches from your head and spray.

Mighty hairspray is Mighty good at its job!
Purchased

This hairspray has a very pleasant scent. It sprays on evenly and gives hair a super hold without weighing it down and feeling stiff. I like it.

Good hold

I really like my sample size of this for travelling but will also think about purchasing the full-size when I'm done with it. This shampoo has good hold and texture but also allows for movement. I would recommend it!

A little goes a LONG way!!!
Purchased

This stuff is powerful! I find myself trying to press the button as lightly as possible because of how "mighty" it actually is! Although, my favorite is the smell. It is kind of earthy, woodsy, musky scent that stays with you all day. I love all of the Number 4 scents and products!

Great Hairspray!

I love this hair spray. It leaves your hair smelling delicious. It provides strong hold but is very light, it doesn't leave your hair feeling crunchy or stiff.

Great Hair Spray: Sturdy yet Flexible

Love the smell! Holds my hair style even in hot humid climates. Doesn't create a crunchy texture, only wonderful flexible hold.

Soft and flexible
Purchased

A great spray if you still want movement in your hair. Doesn't stiffen up. The smell can be overwhelming at first, but doesn't linger.

Awesome!
Purchased

I have thick, coarse hair that can get hard to manage sometimes. I have a hard time keeping my bangs from falling flat sometimes and this product really helped with that. Now, I don't have to lug around a big can of hairspray because this is strong enough to hold my style, yet relaxed enough not to give me helmet head! This is a winner!

Great hold

I was skeptical about a non-aerosol hairspray, but I really like this one! It has a great hold, not sticky or clumpy. You can still comb through your hair if needed after using. I would like to purchase this product.

Love it!
Purchased

I've tried no. 4 pump hairspray. And I loved it! But I think I like the aerosol can even better... So light and airy and keeps hair in place without the frizz! Sprayed some in on a humid day and my hair stayed put. Definitely a good investment
