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.

How to Keep Sleek All Week, Mon Ami!

Now that we’ve tackled the humidity beast and have our hair feeling like the silk of a couture gown, how do we keep it looking effortlessly chic all week? 

We’ve got an extra bonus styling tip up our sleeves for you today to help you slay sleek.

Consider it the “pineapple trick” for bedtime. No, we’re not talking fruit salads, but a loose, high ponytail to keep those curls intact or that sleekness smooth.

Silk scrunchies? Absolutely Darling, because we’re all about luxury meeting practicality.

Be You, Tres Chic: Embracing Your Natural Hair Texture

Soak up Some Vitamin Sea: Protecting Your Hair from Sun & Salt

Now that we have your hair looking sleek and chic for any summer soirée, it’s time to think about protecting it from the inevitable sun and salt damage. Number 4’s Thermal Styling Spray is your go-to for shielding your hair from heat styling and UV rays while at the beach or pool.

And don’t forget to treat those locks with a weekly nourishing hair mask, such as N4’s Reconstructing Masque, after a day of soaking up the sun and salt water. It’s the sleek treat your hair can’t beat.

Reliable Product!

I have actually been buying this shampoo for about 15 years for myself. I also used this on my daughter's hair when she was 7yo and we liked the results so much that she is still using it now at 16yo. The results are reliable and safe on my colored hair.

Bonjour Heather, thank you for the lovely review! Happy to hear you and your daughter enjoy the Clarifying Shampoo and thank you for your loyalty!

Jennifer Brown
My Scalp's best friend!

I've been using No4 Clarifying Shampoo since day one, can't imagine using anything else. Strong enough to clarify my scalp from product residue, and gentle enough not to cause issues, it's a perfect addition to my weekly at home spa treatment! Super happy the large jug is open to public purchase!

Bonjour Jennifer, thank you for the lovely review and for being a loyal Number 4 Hair Care customer! So happy to hear you enjoy the Clarifying Shampoo!
