All DevaCurl® products are safe to use. Our products have gone through rigorous testing and adhere to all relevant regulations for product safety before they reach the market.
All of our products have been dermatologist co-developed, but what does that mean? We enlisted the expertise of Board-Certified Research Dermatologist Dr. Zoe Diana Draelos to test our products for skin safety and hair efficacy.
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)!
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.
Our products go through a lot before they get to you to ensure they meet strict quality and safety requirements.
Stability Test
Formulas are placed in extreme environmental conditions for a period of 90 days. These conditions vary in temperature and light levels to simulate what the product may be exposed to during its life cycle and ensure its stability. These tests confirm that the formula will maintain its intended physical, chemical and microbial properties throughout its shelf life.
Microbiological Challenge Test
Products are exposed to bacteria to ensure that preservative ingredients are doing their job to keep the product safe from contamination. Every batch of our products passes micro challenge tests at our manufacturers before being shipped to our warehouse. We use non-toxic, effective preservatives to keep the product (and you) safe.
pH
All formulas are measured with a pH meter to determine the pH of the product and confirm that it is within that product's specification.
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.

Preservatives are used to keep cosmetic products free from the growth of bacteria, yeasts and molds during its normal usage cycle.
We use approved, effective preservatives that have been comprehensively assessed by the FDA and Cosmetic Ingredient Review (CIR), as well as our own independent clinical safety testing. We monitor emerging scientific research and regulatory developments to ensure our formulations remain non-toxic.
No, we do not use formaldehyde nor formaldehyde donors as a preservative in any of our products.
Phenoxyethanol is one of the most common preservatives used in cosmetic products – it keeps products free from the growth of bacteria, yeasts and mold during their life cycle. Phenoxyethanol has a proven track record as a safe and effective preservative. It also occurs naturally in green tea and chicory.
The US FDA and Europe’s Scientific Committee on Consumer Safety have both confirmed that phenoxyethanol is safe for use as a preservative at levels up to 1%. The amount of phenoxyethanol used in our products is below these regulatory safety standards and is safe.
We use fragrance in our products to enhance your hair care experience, delivering fresh, clean, and luxurious curls.
Our fragrances are made up of many natural and synthetic components, some of which are considered allergens but are still approved by International Fragrance Research Association (IFRA) global safety standards. IFRA standards ban or set limits and criteria for the safe use of certain ingredients based on scientific evidence and consumer insights. As with any product, if you have a negative experience (e.g., itchy scalp) that you think may be related to use, you should stop using the product and contact a doctor or dermatologist if symptoms persist.
The majority of our new bottles are made from 50% recycled ocean-bound plastic to reduce our eco-footprint. In addition, we have some bottles made from 50% as well as 35% recycled plastic. All tubes are made from 30% recycled post-consumer resin (PCR). All of our bottles, tubes and aluminum cans are recyclable.
After our products are manufactured, they are stored at our logistics partner before being delivered to our customers. Our products are stored in a warehouse at an ambient temperature based on industry standards and confirmed by our testing protocols.
All of our products, other than our tools and accessories, are manufactured in the USA. Our DevaTowel and DevaDryer are manufactured in China.
