Keratin Powder


Keratin Powder Improves Immune System Function, as well as Fiber Compounds which Improve Digestion.

What is Keratin Powder?

Keratin powder is a processed form of keratin, a vital, insoluble protein that provides structure and protection to hair, skin, and nails. Keratin powder is a popular ingredient in hair care products (like shampoos and conditioners) as it’s believed to help smooth and strengthen hair. It can also be found in nail care products and supplements and has applications in laboratory research.

Common Sources

The powder is made by extracting keratin from animal sources like feathers, horns, wool, and hooves. This keratin then undergoes hydrolysis, broken into smaller fragments before being dried and ground into a fine powder.

Mechanisms of Action

The mechanisms of action behind this powder are multifaceted. Hair care products may work by temporarily filling in gaps or damage along the hair shaft, creating a smoother surface that reduces frizz and improves manageability. Keratin may form a protective coating on the hair, reducing friction and helping prevent further damage. Additionally, some theorize that the smaller keratin peptides in the powder might be absorbed into the hair structure, providing some strengthening effect. In cosmetics, keratin powder is believed to have a similar smoothing and strengthening effect on nails.

Potential Health Benefits

Keratin powder is often touted for its potential health benefits, particularly in hair, skin, and nail health. Here are some of the possible benefits:

Hair Strength and Repair

Keratin is a critical component of hair structure, so using keratin powder in hair products may help strengthen hair strands, reduce breakage, and repair damage from heat styling, chemical treatments, and environmental factors.

Frizz Reduction

Keratin can help smooth the hair cuticle, which may reduce frizz and enhance the overall appearance of the hair.

Increased Shine

Keratin can improve the hair’s natural shine and luster by coating the hair shaft.

Nail Health

Some proponents suggest that using keratin supplements or keratin-infused nail products may strengthen nails and promote their growth.

Skin Health

While less studied than its effects on hair and nails, keratin is also present in the skin. Keratin products or supplements may support skin health, improving elasticity and hydration.

Industry Applications and Uses

This compound is being used in numerous industries. The most common application is in the cosmetics and hair care sector, where it’s included in shampoos, conditioners, and treatments aimed at enhancing smoothness and manageability. Additionally, keratin supplements are marketed for hair, skin, and nail health. Beyond cosmetics, keratin has applications in textiles as a biodegradable fiber and finishing agent. Its potential in medicine is significant, with applications in wound healing, drug delivery systems, and biomaterials. It has even been used in agriculture as a component in fertilizers and animal feed. Further exploration shows promise for keratin’s role in bioplastics and sustainable packaging materials.

Dosage Guidelines

General guidelines suggest a daily dosage ranging from 400 milligrams daily for adults.

How Does the Origin and Processing of Keratin Affect Its Quality, and How Well Can My Bbody Use It?

The quality of keratin powder and its usefulness to your body depends on both its origin and processing. The animal source type influences amino acids’ makeup in the keratin and potential impurities. Keratin is hydrolyzed or broken into smaller fragments to improve its usability. The extent of this process and the methods used play a significant role. Your body may more readily absorb keratin that matches human keratin more closely and has undergone precise hydrolysis. Additionally, proper processing ensures the purity of the final product, and the solubility plays a role in how readily the body can use it.

Safety and Side Effects

For most healthy adults, taking keratin supplements for a short time is likely safe when following the recommended dosage.

Potential Side Effects

Allergic Reactions: Individuals with sensitivities to animal products (keratin is usually derived from animal sources) might experience allergic reactions. Symptoms could include skin irritation, hives, or, in rare cases, difficulty breathing.

Digestive Issues: Taking keratin supplements might cause minor digestive issues like bloating, gas, nausea, or an upset stomach in some people.

Unknown Long-term Effects: The long-term effects of taking keratin supplements in high doses are not fully understood. More research is needed in this area.

Important Considerations

Not for Everyone: Keratin supplements may only be suitable for some. Consult your doctor before taking them, especially if you have any of these conditions:

  • Pregnancy or breastfeeding
  • Underlying medical conditions (kidney or liver issues)
  • Taking medications

How to Store This Ingredient?

To ensure its longevity and effectiveness, following these steps are essential:

  1. Store keratin powder in a cool, dry place away from direct sunlight and heat sources.
  2. Keep it away from humid areas like the bathroom.
  3. Store keratin powder in an airtight container.
