Unlocking sleek summer hair care

Unleash Your Inner Gloss Goddess: Taming the Wild Weather

Here’s a little secret that the summer has been keeping from you – humidity is the ultimate party-crasher of your hair game. Think about it. The penalty for soaking up the sun is your hair gulping up the moisture in the air leading to a pouty hair affair? We think not! Whether your hair is fine and listless, curly and rebellious, or thick and coarse, we’ve got you covered with tailored tips and tricks to minimize the drama and maximize the sleekness from your N4 stylistic squad.

The Mane Event: Sleek Styling Secrets for Every Hair Type

For those among you with fine hair, a light touch, and plenty of hydration is needed to help your feather-soft strands stay afloat. Number 4’s Hydrating Shampoo is your knight in shining armor to do just that.

Curly ladies, we feel your pain! Taming those wild curls can be as tricky as making the perfect macaron, but fret not! Number 4’s Hydrating Conditioner paired with Super Comb Prep & Protect is going to be your winning game to rock those curls in style this summer. It’s your ticket to live life tangle free and tastily tousled instead.  

This is one product that we recommend everyone packs for their summer vaycay, as it protects not just against heat but also the environment including humidity too.

For those blessed with thick or coarse hair, Number 4’s Mighty Hair Spray will keep those locks looking sleek without any overwhelming grease.

These are your go-to products to beat the heat and keep oh-so sleek.

More On Obtaining the Coveted Sleek Hair Look!

Number 4’s botanical goodies take the center stage when it comes to those coveted sleek vibes.

From locking in moisture with N4’s Blow Dry Lotion applied to damp hair, to the magic of the Smoothing Balm which offers unparalleled heat and environmental protection, these top tips and pro products will ensure your hair stays sleek under the summer sun. Not to mention the hair taming that Fluoro 5 Elixer offers, allowing your strands to be their flyaway-free, glossy best all day long.

We also advise snoozing on a luxurious silk pillowcase, investing in a high-quality hairbrush, and the magic touch of N4’s Texture Styling Cream to help keep tresses frizz-free, delectably sleek, and perfectly sublime no matter what the weather.

Round it all off with N4’s sweet, not salty, shine-boosting Sugar Texturizing Spray, for a final touch of chic, a la Parisienne.

Elizabeth R.D.
Great product, horrible bottle

The hairspray is great. It smells good, holds well without being sticky and feels natural. But the bottle leaks hairspray all over my hand and vanity with every use. Major pain. Wish I had paid attention to the other review that said this, because I really hate it and it’s going to keep me from reordering.

Bonjour Elizabeth, thank you for taking the time to leave a review! We are sorry to hear about the leaking. Please feel free to reach to our Customer Service team at [email protected] on how to best resolve this for you.

Kelsey Knodel
Worth it

So amazing to use to style your hair and also love the heat protection. I'd you're on the fence give it a try. My hairstylist introduced me to this and now I recommend to all my friends.

Bonjour Kelsey, thank you for the great review! Glad to hear you love the Mighty Hair Spray!

Linda Skiles

It seems great so far.
I love your shampoo and conditioner
And how mice you are to deal with.

Restore & Repair Oil

This serum is amazing! I found this little gem by accident and I'm so glad I did! A little goes a long way and it does NOT make your hair greasy. Your hair will look healthy and shiny!


Awesome product! Consistently a top seller in our salon. However, the shipping rates for our salon over the past two years has become double-triple what we pay for any of our other vendors. We have spoken to N4 about this and they provided us with an order sheet we could fill out that would save us a little bit of money, but the shipping cost has definitely deterred us from ordering as often as we have in the past

Bonjour Megg, thank you for taking the time to leave a review. We understand that salon shipping rates are not always fun. One of our team members will be reaching out to see how we can best assist on your situation.

  1. Michelle

    Strong but not stiff. Shiny but not sticky. Never a flaky residue! Just locks in my hair style and keeps flyaways at bay. I love it!

  2. emboog

    Another LOVE for N4. After you’ve used this, you’ll realize not all hair sprays are created equal. I’ve actually driven 30 miles just to get this hair spray. Seriously.
