Dermatologist Co-Developed
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.
Safety Standards
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:
Package And Manufacturing Testing
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.
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.
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.
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.
