our product philosophy

We are committed to continuously listening, learning, and finding innovative ways to help our curl community love their curls! As your needs have evolved, so have our products. Scientifically-rooted, dermatologist co-developed, and stylist-approved, many of our formulas now have upgraded technology with added benefits to support Curl Flexibility™.

In addition to the testing we have performed at independent labs, we make sure to test our products on actual people in our salon. Devachan Salon is our think tank and product playground where we put formulas to the test with our stylists. As a result, each new product is perfected and only introduced to the market after receiving their stamp of approval and undergoing strict safety testing protocol.

It’s in the best interest of your curls!

SLS/SLES Sulfates can strip the hair of its natural oils and since curly hair can dry out quite fast, we’ve chosen to formulate without them.

Silicones are synthetic ingredients made up of hydrogen, oxygen and carbon. They are widely used in hair products to give that feeling of a moisturized slip but in reality, it’s just coating the strands and acting as a filler. Using silicones on a regular basis can cause major buildup weighing down your hair.

Lastly, parabens are a type of preservative that basically help deter bacteria and mold. While parabens allow products to last super long, they can cause curly hair to dry out and frizz.

We want the best for your waves, curls and coils while providing you with ultimate Curl Flexibility™ — get more details on what our new products are formulated without here.

The bunny symbol on our products communicates our commitment to being cruelty-free in compliance with the Leaping Bunny Program.

As a Leaping Bunny certified company, we commit that we will not conduct any animal testing of our products, or their ingredients, at any stage of product development. Our manufacturers and ingredient suppliers must make the same pledge and we obtain written declarations from them to ensure our products are cruelty-free. All DevaCurl products are manufactured in compliance with the Leaping Bunny standards and are free of animal testing.

We know that our curl community wants products that are safe and effective. That’s why all of our products comply with the safety and manufacturing regulations for cosmetics in the US, Canada and the European Union (which has some of the strictest cosmetics safety rules in the world)!

Formula Safety Testing

Curly (wavy and coily) hair is the best hair, and we want to keep it that way. Every single DevaCurl® formula has been tested to ensure that your curls get the TLC that they need. Here’s how:

Safety In Use Testing

350 Curly people. Four weeks. Happy Curls. All of our products undergo “Safety-In-Use Testing”, or SIU, by Board-Certified Dermatologist and well-known hair expert, Dr. Zoe Draelos. During SIU, Dr. Draelos assessed all of our products for the potential to have an adverse reaction under normal use conditions over a 4-week study period. The result? 350 happy curls at the end of 4 weeks. No adverse events occurred during SIU – that means no irritation, no scalp redness and no dryness. During the SIU, we also asked participants what they thought about the products and those results support the claims you see on our bottles! These tests confirm that all of our curl-friendly products are safe and that they deliver the results you have come to expect from DevaCurl®.

Hair Breakage Test: Tensile Break Strength

Did you know that curly hair has more disulfide bonds than straight hair which makes it more susceptible to breakage? We have formulated every single DevaCurl® product with this in mind and the Tensile Break Strength Test keeps us honest. It determines if our products decrease the strength of the internal hair structure or have the potential to permanently change curl pattern. Based on these tests, we know with certainty that all DevaCurl® products are curl-friendly – our products have no negative effect on the break stress or break extension of either virgin or bleached hair.

Product Allergen Test: Human Repeat Insult Patch Testing

Let’s be real – allergies aren’t fun. In the HRIPT, all of our products were applied multiple times to a patch of skin over the course of 3 weeks. Our product showed no potential for skin irritation or allergic contact sensitization. All test results were signed, sealed, and delivered by a Board-Certified Dermatologist.

Package Compatibility

Our formulas and packaging swiped right on each other and plan to live happily ever after ::swoon:: Every one of our products has to pass “package compatibility testing” before it gets on the shelf. This test confirms that there are no safety or quality issues that occur from the interaction of our formulas and their intended packaging over a period of several months at extreme conditions. The results confirmed that they’re a perfect match.
