Keratin Protein: The Building Block of Beauty
Discover keratin, the fibrous structural protein vital for healthy hair, skin, and nails, and its growing popularity in the beauty industry.
What is it?
Keratin is a key structural fibrous protein, acting as the primary building block for your hair, skin, and nails. Insoluble in water, this protective protein is less prone to tearing or scratching than other cells your body produces. There are two main types: alpha-keratins, found in mammals, and beta-keratins, found in reptiles and birds. Its structure, composed of amino acids, forms long filaments that create a strong, supportive framework, providing resilience and protection to epithelial cells from damage and stress.
Why is it trending?
The beauty and personal care industry is seeing a surge in demand for keratin-infused products. Consumers are increasingly seeking solutions for strengthening hair, repairing damage, and achieving a smooth, glossy finish. This has popularized salon keratin treatments, also known as Brazilian blowouts, which smooth hair cuticles to reduce frizz and enhance shine for months. Additionally, the trend towards natural and clean beauty ingredients has boosted the popularity of keratin, which can be derived from sources like wool, feathers, and horns.
How does it affect people?
Keratin-based products can make hair smoother, shinier, and more manageable. Treatments can significantly cut down drying and styling time. However, some salon treatments contain formaldehyde-releasing chemicals, which are known carcinogens and can cause irritation to the eyes, skin, and respiratory system. For those seeking benefits without the risks, many at-home products like shampoos and serums contain keratin hydrolysates that can help fortify hair over time. Always check product ingredients and consult with professionals.
