Find the Best Treatment Product for Your Hair Type

Bring the Valentine’s Day spirit into your self-care routine this month. Fill your shower with pink hues and the scent of roses—try out your favorite formulas in our signature (and festive!) Flamingo color, and in our beloved floral Strike A Rose scent. 

Straight Hair

Our pick: Custom Hair Serum

This custom formula is ideal for straight hair because its lightweight feel won’t weigh down thinner strands.  It’s a multitasker that treats, preps, and styles at the same time.  The mix of Jojoba Oil and Sunflower Seed Oil smooths frizz, enhances shine, and protects hair from heat. 

Wavy Hair

Our Pick: Custom Styling Primer

For our wavy haired friends who love to use hot tools to enhance their natural texture, this one’s for you!  This custom formula uses provitamin B5 to provide the ultimate protection against outside irritants like color, UV, and heat (up to 450°) damage.

Curly Hair

Our Pick: Custom Hair Mask 

The perfect pick-me-up for dry hair in need of some extra moisture, the Custom Hair Mask offers deep nourishment and powerful conditioning through a mix of Argan Oil and Jojoba Esters. For best results, use twice weekly and apply for 5-10 minutes before rinsing. 

Coily Hair 

Our Pick: Custom Leave-In Conditioner

We love a two-in-one product that treats while it styles.  No mater the coarseness of your texture this custom formula uses Avocado Oil and Coffee Seed Extract to penetrate deep moisture into your follicles.  Meanwhile, it can be used on wet or dry hair similarly to a curl creme, creating definition and hold for curly and coily patterns.

Winter Haircare Tips: Keep Jack Frost from Nipping at Your Hair

Brace yourselves, winter is coming! But don’t let your hair turn into a frosty fright. With Jack Frost nipping at our noses, it’s easy for our hair to feel more ‘meh’ than ‘yeah’ because of the increase in extreme temperature (cold outside, all heaters blazing on the inside) which leads to your hair becoming fragile and breakage-prone. Which is why we whipped up ten expert tips and tricks for winter haircare to feel your best no matter the weather! 

Hats On!: Rock a chic hat or stylish scarf. It’s like a warm hug for your hair, shielding it from the extreme temperatures outside that induce the winter woes and hair breakage. 

Chill, Don’t Freeze: Trotting out with wet hair? A big no-no! Why? Because wet hair is 3x more fragile than dry hair. Unless you’re auditioning for ‘Frozen’, make sure your tresses are dry upon stepping outside to avoid the dreaded hair-sicles. 

Defy the Static: Winter static can turn you into a frizz magnet. A little Custom Leave-In Conditioner or Custom Serum can be your secret anti-static charm by putting extra moisture into the hair. 

Turn Down the Heat: Hot showers might feel heavenly, but your hair might not agree. That hot water sucks all the moisture out of your hair while cold water seals cuticles, giving you an added boost of shine. Cold water might be a big ask so let’s at least embrace the lukewarm life – your strands will thank you!

Humidify to Beautify: Combat dry, indoor heat with a humidifier. It’s a two-for-one because not only will it benefit your hair by adding moisture back to it but it also benefits your skin. It’s like a spa day for your hair and skin, every day!

Towel Transformation: Ditch the rough towels and switch to a microfiber superhero or a pure cotton sidekick for a gentler, kinder drying experience.

Play Hard to Get: With your shampoo, that is. Extend those wash days and keep the natural oils grooving and moving in your hair because those natural oils protect your hair from damage – they thing we all want to avoid. 

Mask and Relax: Weekly hair mask ritual? Yes, please! It’s like a nourishing feast for your hair. Pamper party for one, coming right up thanks to our Custom Hair Mask

Cool It with the Hot Tools: Hot tools = damage. Damaged hair is even more prone to the extreme elements of winter. Let’s give the hot tools a rest sometimes. Embrace your hair’s natural vibe or if you must turn up the heat, use our Custom Styling Primer to minimize the damage. 

Oil It Up: Treat your hair to some oil-serum luxury. Our Custom Serum is like a smoothie for your strands – nutritious and delicious!

Et voila! Winter haircare on tap. What tips or tricks do you use during the winter months? Anything we should add to this list?

Ingredient of the Month: Rose Extract

The Ingredient of the Month series highlights one of our meticulously-selected ingredients. Get to know them all on our newly-launched Ingredients Page.

Welcome back to another installment of Ingredient of the Month. This time around we’re highlighting one of our most beloved ingredients — rose extract. Found in multiple best-selling Function of Beauty formulas, rose extract offers an array of notable benefits for the hair that you should know about. Here, everything you need to know about rose extract. 

Main benefits: Delivers moisture to the hair, helps prevent split ends, balances excess oil + flakes
GOALS: fix split ends hair goal for custom hair serum + custom leave-in 

Widely renowned for its highly therapeutic benefits, rose extract is a time-tested ingredient commonly used in a variety of personal care products — from serums and moisturizers, to shampoo and conditioner. Rich in vitamins A, C, D, and E, as well as essential fatty acids, rose extract is a powerful antioxidant with both soothing and hydrating properties. Moreover, it can help balance oil on the face or scalp. When it comes to the hair, specifically, rose extract aids in preventing split ends, delivering deep moisture to dry  frizzy strands, and keeping oil under control. Rose extract also has a stunning floral scent profile, which makes it an excellent ingredient to use in natural fragrances. Currently, you can find rose extract in our hair serum and leave-in formulas. It’s worth noting that we use a synthetic form of rose because, believe it or not, producing a single pound of rose essential oil can take roughly 10,000 pounds of rose petals. Pretty wild, right? That’s why we went the synthetic route, to help sustain our Earth’s natural resources.
