Serine (Amino Acid)

Serine is a naturally occurring amino acid that is essential for the production of proteins in the body, including keratin, the main protein in hair. It is a non-essential amino acid, meaning the body can produce it, but it is also obtained from dietary sources such as meat, soy, and dairy. In hair care, Serine is valued for its hydrating, strengthening, and restorative properties, making it an important ingredient in products designed to nourish and protect the hair.

Serine is known for its excellent moisture-retention properties. It is hygroscopic, meaning it attracts and holds onto water molecules. When used in hair care products, Serine helps to keep the hair hydrated, preventing dryness and promoting softness and smoothness. Hydrated hair looks shinier and more vibrant, as well as feels more supple and manageable.

Serine contributes to the production and maintenance of keratin in the hair. As a key component of proteins, Serine helps support the structural integrity of the hair shaft, enhancing its strength and resilience. This makes it particularly beneficial for preventing breakage, split ends, and damage from environmental factors, styling, or chemical treatments.

By supporting keratin production and maintaining proper moisture balance, Serine plays a role in improving the elasticity of hair. This means that hair is more flexible, less prone to breakage, and better able to withstand stretching and manipulation. Hair with improved elasticity looks healthier and has more natural movement and bounce.

Serine is not only beneficial for the hair itself but also for the scalp. It helps maintain a healthy scalp environment by promoting moisture retention and preventing dryness or irritation. A well-moisturized scalp is essential for optimal hair growth and health, as it creates the right conditions for hair follicles to thrive.

Serine’s ability to support the protein structure of the hair helps to repair and restore damaged hair fibres. It can fill in gaps and weaknesses in the hair shaft caused by damage from styling, UV exposure, or chemical treatments. This helps the hair regain its strength and resilience, reducing the appearance of damage and promoting a smoother texture.

Serine contributes to a smooth and shiny appearance by helping to align the protein structure in the hair and improving moisture balance. Well-moisturized hair has a natural shine and feels softer to the touch, enhancing overall hair texture and appearance.
