our commitment to safety & quality


At DevaCurl, safety, quality and a positive experience are at the center of who we are. All of our products are safe to use – they are subject to rigorous and thorough testing, to ensure they meet both internal quality assurance and regulatory requirements before they reach the market.

This includes:

Stability Testing: This test exposes our products to a range of temperatures including cold, freezing, ambient (60-78 degrees F), and extreme heat for several months to ensure stability. We check the product’s pH, viscosity, odor, and appearance to confirm that each remains stable under these various conditions.

Microbiological Challenge Testing:
This test involves exposing products to bacteria to ensure our ingredients are doing their job to keep the product safe from contamination. We use non-toxic, effective preservatives to keep the product (and you) safe.

HRIPT (Human Repeat Insult Patch Test):
This test is performed on people’s skin to test for irritation and allergy potential to confirm that it’s safe for use.

Ocular Testing
: This test is to ensure our product formulas are not harmful to the eyes.

Packaging Compatibility Testing
: This test confirms that there are no reactions between the package and the formula over a period of several months at extreme heat conditions.

Product Storage:
We also store all our products in an ambient temperature (60-78 degrees F) warehouse based on industry standards and confirmed by our testing protocols.

Additional Evaluation
: For every DevaCurl product, before each batch is released for distributing to salons, retailers, or customers, the product is evaluated and tested for appearance, odor, pH, viscosity and passes additional microbiological testing.
