Understanding Keratin

Keratin is a fibrous structural protein found in the outermost layer of the skin, hair, nails, feathers, and hooves of animals. It is responsible for providing strength, resilience, and protection to these structures. The primary building block of keratin is an amino acid called cysteine, which contains sulphur.

How is Keratin produced by the human body?

Keratin is naturally produced by the human body through a process called keratinization. It is an integral part of the structure and function of various tissues, including the skin, hair, nails, and outermost layer of the epidermis.

The production of keratin begins in the basal cells of the epidermis, the outermost layer of the skin. These basal cells undergo a process known as keratinocyte differentiation, where they progressively move towards the skin's surface. As they move upward, they undergo structural and biochemical changes, eventually transforming into fully mature keratinocytes.

During the process of keratinization, the keratinocytes produce keratin proteins, which contribute to the strength, elasticity, and waterproofing properties of the tissues they form. As the keratinocytes move towards the surface of the skin, they fill with keratin proteins and undergo a process called cornification. This involves the aggregation of keratin filaments within the cells, leading to the formation of a tough, protective layer of dead cells known as the stratum corneum.

In the hair follicles, specialized cells called keratinocytes produce keratin proteins that form the hair shaft. These keratin proteins provide structural support and give hair its strength, texture, and resilience.

Similarly, keratin production also occurs in the nail matrix, the region beneath the nail where nail growth occurs. The specialized cells in the nail matrix, known as matrix keratinocytes, produce keratin proteins that contribute to the formation of the nail plate.

The production of keratin is a continuous process as the older keratinocytes move towards the skin's surface, shed, and are replaced by new cells originating from the basal layer. This turnover process helps maintain the integrity and protective function of the skin, hair, and nails.

It is worth noting that the production of keratin can be influenced by various factors, including genetics, nutrition, hormonal changes, and overall health. Imbalances or disruptions in the keratinization process can lead to conditions like dry skin, brittle hair, hair loss and nail disorders.

How is keratin used in the beauty industry?

Keratin has become a popular ingredient in the beauty industry due to its beneficial properties for hair and skin. Here are some common uses of keratin in the beauty industry:

1. Hair Treatments and Products:

Keratin is widely used in human hair products, especially in keratin treatments designed to improve the strength, texture, and appearance of hair. The most well-known application is keratin hair straightening or smoothing treatments, also known as a Brazilian blowout. These treatments involve applying a keratin-based solution to the hair, followed by heat styling with a hair dryer and flat iron which helps to temporarily smooth and straighten the hair cuticle, reduce frizz, and enhance shine.

Keratin is also found in shampoos, conditioners, serums, and masks formulated to strengthen and repair dry hair, damaged hair and other hair types. These products often contain hydrolysed keratin, which has smaller molecules that can penetrate the hair shaft, providing structural support and helping to rebuild damaged protein bonds and increase hair strength.

2. Nail Care:

Keratin is a key component of healthy nails. It contributes to their strength and resilience. Nail care products often contain keratin to help strengthen and protect the nails, preventing breakage and promoting overall nail health. Keratin-infused nail polishes, nail treatments, and cuticle creams are commonly used to improve the appearance and condition of nails.

3. Skincare:

While keratin is predominantly associated with hair health, keratin protein is also found in some skincare products. Keratin peptides or hydrolysed keratin may be included in moisturisers, anti-aging creams, and serums to promote skin firmness, elasticity, and hydration. These keratin derivatives are believed to help improve the overall texture and appearance of the skin.

4. Mascara and Eyebrow Products:

In the realm of eye makeup, keratin is sometimes included in mascaras and eyebrow products. The addition of keratin is claimed to enhance the strength and thickness of eyelashes and eyebrows, providing a volumizing and conditioning effect.

It is important to note that the use of keratin in beauty products can vary, and not all products labeled as "keratin-infused" or "keratin-based" contain the same type or quality of keratin. Therefore, it is crucial to review the ingredient list and ensure that the product aligns with your specific needs and preferences.

Overall, keratin plays a significant role in the beauty industry, contributing to hair treatments, nail care, skincare, and eye makeup products. Its inclusion aims to enhance the appearance, strength, and health of various beauty features, offering consumers a range of options to address specific concerns.

Sources of Keratin

Keratin can be derived from both animal and plant sources. The most common animal sources of keratin include:

1. Hair: Animal hair, such as sheep wool, is a common source of animal keratin. This includes ingredients like sheep wool keratin, hydrolyzed keratin, or keratin amino acids.

2. Feathers: Keratin can also be obtained from feathers of various birds, including chicken feathers.

3. Hooves and horns: Some keratin-based products may be sourced from the hooves or horns of animals, such as cows.

Vegan Alternatives

While the traditional sources of keratin are animal-derived, advancements in biotechnology have led to the development of vegan alternatives. Plant-based sources of keratin are now available, offering cruelty-free options to those following a vegan lifestyle. These plant-derived keratins are typically derived from sources such as wheat, corn, soy, or other plant proteins. They are often labeled as "vegetable keratin" or "plant-based keratin."

Determining Vegan Status

Determining whether keratin is vegan or not can be challenging due to the lack of consistent labelling practices and transparency in the cosmetics industry. To ascertain the vegan status of a keratin-based product, it is crucial to examine the ingredient list and verify the source of keratin used.

It is essential to note that some products may claim to be "vegan-friendly" or "cruelty-free" but still contain animal-derived keratin. Hence, it is advisable to look for certifications from reputable organizations such as the Vegan Society or Leaping Bunny, which provide assurance that a product is genuinely vegan and free from animal ingredients or testing.
