The Top 5 Questions You Have About Keratins

1. What is Keratin?

Keratin is a ”highly durable protein that provides structure to several types of living tissues.” Keratin is also a major protein found in mammalian hair and hooves along with nails, horns, fish scales, bid feathers and beaks, and skin.

2. Why is Keratin Important?

Keratin as an invaluable protein which has been found to “regulate key cellular activities, such as cell growth and protein synthesis.” Another important quality is “..its ability to flex in multiple directions without tearing.” This is why healthy keratin presence is so important in preventing damage to skin and coat.

3. Does topical application of Keratin make difference?

Natural production of Keratin is essential for strong skin and coat. However, some question weather topical application has any effect. According to current scientific studies, the answer appear to be yes! A peer reviewed article from the National Center for Biotechnology Information (NCBI) published the following findings:

STUDY: Cosmetic effectiveness of topically applied hydrolysed keratin peptides and lipids derived from wool.


Skin moisturisation, elasticity, feel and appearance can all be improved through the topical application of protein hydrolysates. Recent studies suggest that supplementing intercellular lipids of the stratum corneum can enhance the functioning of the skin.


Significant differences were found between the control and treated sites, with the treated areas showing an increase in hydration and elasticity as a result of keratin peptide application. Measurements also indicated that the keratin formulations reinforce the skin barrier integrity, improving its water-holding capacity.

4. Is “Hydrolyzed” Keratin better?

Keratin’s can range in quality, and can differ from where they are sourced. Some keratins are made from plants and some animal by-products. A common animal by-product is bovine blood plasma. At Pure Paws, we choose not to use this common source, and instead use Hydrolyzed Keratin derived sheep’s wool. In this way, we get closer to the molecular makeup of an animal keratin without causing them harm

5. Are Keratin Products safe?

According to the Environmental Working Group (EWG), Hydrolyzed Keratins are safe and non-carcinogenic. The current concern over keratin product comes from some keratin “smoothing products” used in hair straightening processes like “Brazilian Blowouts”. These salon products can sometimes contain methylene glycol, which releases formaldehyde, a known carcinogen To help consumers stay safe, OSHA has listed other names that formaldehyde are sometimes disguised as in “formaldehyde-free” products. This includes, methylene glycol, formalin, methylene oxide, paraform, formic aldehyde, methanal, oxomethane, oxymethylene, or CAS Number 50-00-0. At Pure Paws, non of our products contain methylene glycol.

So those were your top 5 questions. So what lines do we recommend for you to strengthen your dog’s skin and coat? The name says is all – The Pure Paws Forte line. The word forte is derived from the French word fort, meaning “strong.” The Forte line is packed with Hydrolyzed Keratins to help increase moisture and elasticity, while strengthening each strand of hair to prevent breakage while brushing. It also provides added moisture with panthenol, aloe vera, and jojoba oil!
