What is Hydrolyzed Keratin?

Definition and Composition

Hydrolyzed keratin is a protein derived from keratin, a structural protein found in hair, skin, and nails. The term "hydrolyzed" refers to the process of breaking down the keratin protein into smaller peptides or amino acids, making it more bioavailable and easier for the body to absorb. Hydrolyzed keratin is renowned for its ability to strengthen and repair damaged hair, skin, and nails.

Sources of Hydrolyzed Keratin

Hydrolyzed keratin can be sourced from various animal proteins, including:

  • Sheep Wool: A common source due to its high keratin content.
  • Feathers: Often used in hair care products.
  • Human Hair: Occasionally used in premium products.
  • Other Animal Sources: Various formulations may include keratin from different animal origins.

Production Process

The production of hydrolyzed keratin typically involves several steps:

  1. Extraction: Keratin is extracted from animal sources, such as sheep wool or feathers.
  2. Hydrolysis: The extracted keratin is treated with water, enzymes, or acids to break it down into smaller peptides. This enhances its solubility and absorption.
  3. Purification: The hydrolyzed keratin is purified to remove impurities, resulting in a clear, viscous liquid that can be easily incorporated into beauty products.

Benefits of Hydrolyzed Keratin

Hydrolyzed keratin offers numerous benefits for hair, skin, and nails. Some of its most notable advantages include:

  1. Repairs Damaged Hair: Daily styling, heat exposure, and environmental factors can damage hair. Hydrolyzed keratin penetrates the hair shaft and fills in gaps and cracks, restoring strength and integrity.
  2. Enhances Shine: By smoothing the hair cuticle, hydrolyzed keratin increases shine and makes hair look healthier.
  3. Reduces Frizz: It forms a protective layer around each hair strand, reducing frizz and making hair easier to manage.
  4. Strengthens Nails: Hydrolyzed keratin strengthens brittle nails, making them less prone to breaking and chipping.
  5. Moisturizes Skin: When applied to the skin, hydrolyzed keratin helps to strengthen the skin’s barrier, improving hydration and overall texture.
  6. Improves Elasticity: Regular use can enhance the elasticity of both hair and skin, making them more resilient to stress.

Common Uses of Hydrolyzed Keratin

Hydrolyzed keratin is commonly found in a wide range of products, including:

  • Shampoos: Many shampoos incorporate hydrolyzed keratin to strengthen and nourish hair during cleansing.
  • Conditioners: Conditioners often contain hydrolyzed keratin to provide deep hydration and repair damaged hair.
  • Hair Masks: Intensive treatments use hydrolyzed keratin to restore moisture and strength to hair.
  • Skin Creams: Skincare products may include hydrolyzed keratin to improve skin texture and hydration.
  • Nail Treatments: Many nail care products incorporate hydrolyzed keratin to strengthen and protect nails.

What is Methyl Sulfonyl Methane (MSM)?

Definition and Composition

Methyl sulfonyl methane (MSM) is an organic sulfur compound found in plants, animals, and humans. It is a naturally occurring substance that has gained popularity as a dietary supplement due to its potential health benefits. MSM is often used for its anti-inflammatory properties and its ability to support joint health.

Sources of MSM

MSM can be found in various sources, including:

  • Plants: Certain fruits and vegetables, such as garlic, onions, and cruciferous vegetables, contain small amounts of MSM.
  • Animal Products: Meat and dairy products also contain MSM, though in smaller quantities.
  • Supplements: MSM is commonly available in powder or capsule form, making it easy to incorporate into a daily routine.

Production Process

MSM is typically produced through a chemical process that involves:

  1. Extraction: The raw material is obtained from natural sources, often derived from lignin in wood.
  2. Purification: The extracted MSM undergoes purification to remove impurities, resulting in a high-quality compound suitable for supplementation.

Benefits of MSM

MSM offers several health benefits, particularly for joint health and overall well-being:

  1. Supports Joint Health: MSM is known to support cartilage repair and maintenance, helping to alleviate joint pain and stiffness.
  2. Reduces Inflammation: Research suggests that MSM may have anti-inflammatory properties, which can help reduce swelling and discomfort in the joints.
  3. Improves Mobility: Regular use of MSM may improve joint mobility, allowing for greater flexibility and range of motion.
  4. Promotes Skin Health: Some studies indicate that MSM can improve skin hydration and elasticity, making it a valuable ingredient in skincare formulations.
  5. Enhances Recovery: MSM may aid in muscle recovery after exercise, reducing soreness and inflammation.

Common Uses of MSM

MSM is most commonly used in:

  • Dietary Supplements: MSM is widely available in capsule, tablet, or powder form, often combined with other joint-supporting ingredients.
  • Topical Creams: Some creams and gels designed for joint pain relief may include MSM for added benefits.
  • Skincare Products: MSM is increasingly being incorporated into skincare products for its moisturizing and anti-aging properties.

Hydrolyzed Keratin vs. Methyl Sulfonyl Methane: A Detailed Comparison

1. Composition and Structure

Hydrolyzed keratin is a protein made up of amino acids, while MSM is an organic sulfur compound. This difference in composition leads to their distinct functions and uses. Hydrolyzed keratin primarily enhances the health and appearance of hair, skin, and nails, while MSM focuses on supporting joint health and reducing inflammation.

2. Mechanism of Action

  • Hydrolyzed Keratin: Works externally by repairing and strengthening the hair and skin. It fills in damaged areas and creates a protective barrier, enhancing shine and elasticity.
