What is Hydrolyzed Keratin?
What is Collagen?
Hydrolyzed keratin and collagen are both proteins commonly used in skincare and haircare products, but they differ in their composition, benefits, and how they interact with the body.

- Hydrolyzed Keratin: Derived from animal hair, feathers, or hooves, hydrolyzed keratin is a modified form of keratin (the protein that makes up human hair, skin, and nails). It’s processed (hydrolyzed) to break it down into smaller molecules for easier absorption.
- Collagen: Collagen is also an animal-derived protein, commonly extracted from bovine (cow), porcine (pig), or marine (fish) sources. It’s the main structural protein in connective tissues, including skin, bones, tendons, and cartilage.
Keratin vs Collagen: A Deep Dive into Two Essential Proteins for Beauty and Wellness
In the fast-paced world of beauty and wellness, the debate between keratin vs collagen has become a hot topic among consumers and industry professionals alike. These proteins are celebrated for their remarkable properties, and they're often featured prominently in hair and skin care products. But what exactly are they, and how do they compare? Let’s explore the essential details you need to know about keratin and collagen, their functions, benefits, and where each can fit into your health and beauty regime.
Understanding Keratin and Collagen
Keratin and collagen are two vital proteins that play distinct yet complementary roles in our bodies. Here’s a quick overview:
- Keratin: This fibrous protein is primarily found in hair, skin, and nails. It’s known for its protective qualities, giving strength and resilience to these tissues. Variants such as keratin supplements have become popular for those looking to enhance hair health or improve skin resilience.
- Collagen: As the most abundant protein in the body, collagen is crucial for maintaining the structural integrity of our skin, bones, and connective tissues. With applications in both beauty and wellness supplements, collagen is renowned for its skin-regenerating properties.
Basic Information on Keratin vs Collagen
Here’s a deeper look at the characteristics, production standards, and other pertinent details regarding keratin and collagen.
- Aliases and Scientific Names:
- Keratin: Sometimes referred to simply as keratin (keratín in Spanish).
- Collagen: Often indicated by type (e.g., Type I, Type II, etc.), which refers to their different roles in the body.
- CAS Numbers:
- Keratin does not have a specific CAS number common across all types, whereas collagen has specific identifiers associated with its different types.
- Production Standards:
- Both keratin and collagen are widely produced under proper industry standards, with certifications required for safety, efficacy, and quality control.
- Physical Appearance:
- Keratin: Usually yields in either a powder or liquid form, commonly added to hair treatments and styling products.
- Collagen: Known to be available in powder, liquid, and capsule forms.
- Taste and Solubility:
- Both proteins are generally neutral in taste, allowing for easy incorporation into various products.
- Solubility: Collagen is usually hydrolyzed and water-soluble, making it easy to digest, while keratin is less soluble but can be processed to improve solubility for specific applications.
- Common Specifications:
- Particle size varies but typically ranges from 20 to 200 microns.
- Storage and Shelf Life:
- Properly stored, both keratin and collagen can last for 24 months or more under optimal conditions.
The Origins of Keratin and Collagen
Both keratin and collagen have fascinating histories rooted in biology and health:
- Keratin is derived from animal sources, with significant research since the early 20th century focusing on its properties and uses in beauty products like keratin hair treatments and innovations like keratin hair extensions.
- Collagen, introduced into the beauty industry around the 1980s, has snowballed in popularity due to its revolutionary effects on skin elasticity and joint health.
Common Forms in the Market
Both proteins find their way into various products, often tailored for specific applications:
- Keratin: Popular uses include treatments like Brazilian blowouts which temporarily straighten and smooth hair, as well as styling products that promote shine and manageability.
- Collagen: Widely marketed through supplements, such as the keratin supplement for hair or joint health.
Auxiliary Ingredients Used in Production
The production processes for both keratin and collagen often incorporate other ingredients to enhance effectiveness:
- Keratin is sometimes paired with nourishing oils and vitamins, helping to improve hair condition.
- Collagen commonly includes vitamin C to enhance absorption and functionality in the body.
Keratin vs Collagen: Are They Water-Soluble?
When it comes to solubility, collagen has the edge. Hydrolyzed collagen is water-soluble, allowing it to be easily incorporated into beverages or food. In contrast, keratin is less soluble but can still be effectively used in various conditions with the proper formulations.
Where Are Keratin and Collagen Used?
Both keratin and collagen have multiple applications in different markets:
- Hair care: Keratin is often used in shampoos, conditioners, and treatments to enhance shine and smoothness, while collagen is becoming a staple in products claiming anti-aging benefits for hair.
- Skin care: Collagen is touted for its skin elasticity benefits, often used in anti-aging creams and serums.
- Dietary Supplements: Both are available in the form of pills or powders designed to support hair, skin, and joints.
Main Production Techniques
- Keratin Production:
- Common methods include extraction from feathers, hooves, and hair, followed by hydrolysis to improve functionality for use in cosmetic applications.
- Collagen Production:
- Typically derived from animal hides, skin, bones, and scales, collagen is processed through methods like hydrolysis for better absorption and effectiveness.
Benefits of Keratin and Collagen Supplements
Both keratin and collagen supplementation offer various benefits:
- Keratin: Known to improve hair strength, reduce frizz, and enhance overall hair appearance. Many ask, “Is keratin good for hair?” The answer is a resounding yes for those looking to revive damaged or dull hair.
- Collagen: Promotes skin hydration, elasticity, and joint health. Many enjoy the added support for bone density and flexibility, making it a popular choice for those seeking overall wellness.
Potential Side Effects
While both proteins are generally safe, they can lead to side effects:
- Keratin: Overuse may lead to product buildup on the hair, potentially causing it to feel heavy or greasy.
- Collagen: Some users experience digestive discomfort or allergic reactions, particularly if sourced from fish or other allergens.
Mechanisms of Action in the Body
Understanding how they work in the body can shed light on why they’re effective:
- Keratin strengthens and protects hair with its fibrous structure. It provides a barrier against environmental damage and moisture loss.
