About the brand: Royal Keratin

Royal Keratin products have not been tested for formaldehyde content, but the company lists formaldehyde in one of their formulations at less than 2%. There is also the milder formula which they claim to be formaldehyde-free. Both of these treatments are available to consumers via the Royal Keratin website.

When it comes to keratin, tough is good. Its strong protective qualities improve the hair both inside and out. Our unique biopolymer ingredient is virtually a "liquid form of hair" that gently blends with the hair on your head. It brings to hair what it was lacking to begin with and what it has lost over the years. Is the hair dull dry and damaged? Is it curly, wavy, frizzy, overly voluminous or unmanageable? Application of our keratin treatment puts an end to all that. The smaller keratin molecules penetrate the hair cortex improving and repairing the quality of the hair from the inside. The added strength, elasticity and moisture result in the smooth, soft, shiny and straightened effect. The larger molecules coat the hair cuticle and take the environmental insults such as UV rays, smog, and smoke for your hair on the outside. Further damage to the hair shaft is prevented. [link]


A loophole in federal labeling law allows companies to sell "professional use" products without the ingredient label required on all other personal care products, so the use of formaldehyde can be hidden. Nearly all of the hair straightening products surveyed by EWG are marketed for professional use only. Despite these claims, EWG found that consumers can easily purchase "professional use" products through online retailers. Retailers identified for Royal Keratin products are listed below:
