Memorial Day Sale 2022

Take 30% Off in Honor of our Armed Forces this Memorial Day

Take 30% Off in Honor of our Armed Forces this Memorial Day 546 450 Number 4 High Performance Hair Care

Weekday to weekend hairstyleBONJOUR DAH-LING!

Observed on the last Monday of May, Memorial Day falls on the 30th this year so we thought it was fitting to offer all our loyal and devoted N4 customers, 30% off site wide.

Observed now for 154 years and an occasion to pay our respects for those who fought and died while serving in the United States armed forces, Number 4 might have an ethos that’s deeply rooted in European culture, but we’re proud to be a U.S brand and to recognize Memorial Day.

It also seemed fitting that we went back to the first Monday of May, home of a very different but equally notable event, the Met Gala.

Gilded Glamor

This year the theme was “Gilded Glamor” as attendees paid homage to the 19th century era of decadence and prestige. Prestige is 100% a value that we appreciate and strive to represent here at N4 with our exceptional quality, natural ingredients.

So in today’s blog, we thought we’d take you through some of the iconic looks, favored by the red carpet celebs, with of course, the must-have N4 products you need to perfect and polish these styles at home.

And don’t forget, now is the best time to top up and shop your favorite vegan-friendly and organic hair care with our 30% Memorial Day Sale.

Making Hairstory!

Safe to say that the first Monday in May yet again made hairstory!

From Gigi Hadid’s elaborate crimson pony to Lily Collins’ bold bouffant, the hair memo was definitely “go big or go home.”

Hollywood glamor and full-throttle volume was seen everywhere while we were bowled over by Camila Cabello’s effortlessly tousled and stylish undo and Kaia Gerber’s oh so larger than life curls. WOW did she master the art of voluminous curls. Her whole look was nothing short of show-stopping and we are living for that bounce.

And don’t even get us started on Megan Thee Stallion’s sleek bun complete with subtle retro vibe waves.

And while we’re talking retro, we couldn’t pass up a mention of Kris Jenner’s ‘60s style-bob with side swept bangs sweetly framing her face. Nailed it.

We like to think that more than one red carpet Met moment this year was assisted by one of our N4 styling products!

N4 Handbag Essentials

For sure, if we had to pick one handbag essential (difficult as it is because quite frankly the entire range always brings its Hollywood A game) we’d have to single out N4’s Non Aerosol Hair Spray. Cocktail this with N4’s Thermal Styling Spray and you can style and spray your strands to perfection without stiffness.

We hope you take advantage of our sensational savings and if you are stuck for ideas, why not read our BLOG: 3 Handbag Hair Essentials You Need and grab our products recommendations with 30% off TODAY with our Memorial Day Sale for 2022!

I’m a return customer and for good reason

I found No 4 through Birchbox yearsssssssss ago haha. And I searched high and low from several retailers before realizing I can purchase through that website, duh! NOTHING leaves my hair both perfectly clean and deeply thick & shiny like No4. And you can’t beat that scent. So soft and sweet. Love it!

The Best Shampoo!

I’ve tried so many different shampoos through the years, & I always return to this one at some point because it simply works so well. I live in an area that has very hard water, and this helps make sure both my hair and scalp are in good condition even when the water isn’t great. I find this still lathers & cleans extremely well even with hard water.

I’m also 17 months postpartum from having my most recent child and this shampoo is helping maintain the strength of my hair as it continues to regrow after that notorious postpartum hair loss most women go through after a baby. I strayed away from the shampoo for awhile, and my scalp really noticed, as I had extreme dry patches. This shampoo is worth every penny.. and the smell is beautiful but not overpowering. Can’t recommend enough!

  1. Michelle

    This is my holy grail shampoo! The scent is heavenly, and it leaves my hair hydrated but not limp or oily. I believe this product helps keep my highlighted and heat-styled hair looking its absolute best.

  2. baxterdiane689

    I purchased this shampoo thru my salon where I have my hair colored. Initially, upon the first use, my hair felt tangled and stiff. Once I applied the conditioner, it helped, but no shampoo should make your hair feel tangled and rough. The conditioner is great, but the shampoo was not good for my fine color treated hair at all. What a disappointment.

  3. josephine.schagerstrom

    This shampoo is perfect for my colored curly and frizzy hair. Leaves no residue and makes my hair fresh and clean and brings out the true beauty of my hair. I will never stop buying it.

  4. davnbird (verified owner)

    I have been a loyal fan of Number 4 Hydrating Shampoo for years; however, the last bottle I received was totally different from the previous bottle. The product was brown, did not lather at all, and left my hair lank after washing. I will not be buying any more of this brand.

  5. Dora J Crow

    The texture, scent & cleansing w/out stripping my purple color off is sensational. I thought I’d never find a pro product (I am licensed managing cosmetologist) that would meet or exceed all my requirements. It’s luxurious feel & color of the shampoo to begin with is a zen-like experience. Once you get that nectar on your hair & start to shampoo? Heavenly scent of patchouli fills your shower. It leaves hair hydrated & moist. It actually does what it professes to do, unlike so many other products. I adore Number 4! Psst- your man will always want to smell you, wondering what that new scent is that you are wearing!

  6. Lauren

    I got a sample of this in my Birchbox and it is absolutely the most amazing shampoo I’ve ever used! My hair is normally dry and damaged from the blow dryer and curling iron and this shampoo completely transformed it! It’s so soft and I hardly get split ends now. Definitely going to keep buying it 🙂

  7. fawxed

    This shampoo is an absolute DREAM! Super concentrated, a little bit really does go a long way, but it really gets the job done. My tresses are silky and my frizz is greatly minimized. It also smells delightful. Do yourself a favor!

  8. sillyj435

    Love love love this. My hair was so soft and feels so healthy!!! Oh and it smells sooo yummy. I have curly hair and fight with hydration issues. With this I no longer fight. Thanks.

  9. cjtang4u

    I love this line! All of the lines smell great but the Hydrate one is my favorite. This one smells like honeysuckle and I get whiffs of it throughout the day when I use it. A little goes a long way!

  10. molson

    This shampoo has saved my life. Well, technically it saved my hair, but since my hair is a huge part of my life… you get the gist. I have naturally curly hair that easily falls flat and goes frizzy. I have received so many compliments since my hairdresser introduced me to No. 4. and all I have to do is wash and go–no fuss and my hair looks amazing and feels amazingly soft.
    Mega hydrated! I love this stuff and you will, too!!

  11. a1nettie

    I love the way this makes my hair feel. The scent is unique and initially strong and off putting, but when I felt how my hair felt I was sold!Super silky and I don’t feel like I “Need” a conditioner when using this. Excellent!

  12. julesc

    Perfect! I got a sample of both the hydrating shampoo and conditioner in my June Birchbox. Being a cosmetology student who’s currently trying like crazy to grow my hair out, I’m pretty picky about what I’ll put on my head. I decided to give this shampoo a shot and I’m hooked! Seriously, my usually frizzy hair has never felt so clean and soft, it’s even tamed my wiry, damaged ends from bleaching!

  13. emboog

    OMG. You must try this product! No disappointment will be had! Well worth the cost. Promise. Must follow-up with conditioner.
