Keratins are a group of fibrous proteins that play a significant role in maintaining the strength and luster of our skin, hair, and nails. These proteins are naturally found in the human body and are responsible for keeping our hair and nails strong, elastic, and shiny, providing us with youthful-looking skin, and shielding our skin and nails against damage from various external factors. In this post, we will be exploring how keratins work and why they are essential in your everyday beauty routine.

First, let’s understand what keratins are and how they work in our body. Keratins are tough, fibrous proteins that are rich in cysteine, a sulfur-containing amino acid. They are known for their ability to create strong, protective fibers that help strengthen and nourish hair, nails, and skin cells. They are present in the epidermis, hair follicles, and nails, and contribute to their strength and structure. With age, the body’s keratin production decreases, leading to weaker and dull-looking hair and nails, and less resilient skin. Adding keratin supplements or keratin-rich foods to your diet can help restore your skin, hair, and nails to their youthful states.

Second, let’s look at how keratins benefit the skin. The epidermis, which is the outermost layer of your skin, consists mostly of cells called keratinocytes that produce keratin. Keratinocytes play a crucial role in protecting our skin from the harmful effects of sun exposure, pollution, and other environmental factors. They also form a barrier against water loss, keeping our skin moisturized and healthy. Adding a keratin-based moisturizer or serum to your skincare routine can help replenish your skin’s keratin levels and keep it looking youthful, healthy, and glowing.

Third, let’s talk about how keratins contribute to nail strength and growth. Nails consist of layers of tough, keratinized cells, which form a strong, protective shield over the fingertips. Keratin plays an important role in nail growth and strength. A diet rich in keratin-rich foods such as eggs, meat, and fish, along with regular nail care, can help keep your nails strong, healthy, and beautiful. Furthermore, applying a nail hardening or strengthening treatment that contains keratin can help improve the appearance and health of your nails.

Fourth, let’s explore the benefits of keratin for hair. As mentioned, keratin is responsible for keeping hair elastic, smooth, and shiny. However, our hair’s keratin levels decrease with age, resulting in weaker, more fragile hair prone to breakage, damage, and split ends. Keratin treatments, whether in-salon or at-home, can help restore your hair’s natural keratin levels, making it stronger, more manageable, and healthier. Additionally, you can also choose a keratin-infused shampoo and conditioner that help protect your hair from damage and keep it looking shiny and healthy.


Overall, keratins are a powerful tool in your beauty arsenal. They contribute to the strength, elasticity, and luster of your hair, nails, and skin, and help protect them against environmental damage. While our bodies naturally produce keratins, age, diet, and external factors can cause a decrease in their production, leading to weaker, less resilient skin, hair, and nails. Adding keratin-rich foods, supplements, and hair and nail products to your beauty routine can help replenish your body’s keratin levels, keep your skin, hair, and nails healthy, and restore them to their youthful states.
