Isoleucine (Amino Acid)

Isoleucine is an essential amino acid, meaning it must be obtained through diet as the body cannot produce it on its own. It is found in protein-rich foods such as meat, fish, dairy products, and certain plant-based sources like legumes and soy. In hair care, Isoleucine plays a crucial role in supporting the structural integrity and overall health of the hair by aiding in protein synthesis and providing strengthening and repairing benefits.

Isoleucine is involved in the production and repair of proteins like keratin, which is the primary structural component of hair. By supporting the synthesis of keratin, Isoleucine helps to strengthen the hair shaft, making hair less prone to breakage and damage. Stronger hair is more resilient to everyday wear and tear, such as styling, heat exposure, and environmental stressors.

One of the key functions of Isoleucine in hair care is enhancing the elasticity of the hair. By promoting the production of keratin and supporting hair’s structural integrity, Isoleucine helps hair retain its flexibility. This improved elasticity reduces the risk of hair snapping or breaking during combing, styling, or other hair manipulations.

Isoleucine contributes to the maintenance of healthy hair follicles and supports a balanced scalp environment. It helps ensure that the hair growth cycle functions optimally by providing the necessary nutrients that hair follicles need to thrive. By improving hair follicle health, Isoleucine may help promote thicker, healthier hair growth over time.

Like other amino acids, Isoleucine plays a role in repairing damaged hair fibres. Whether hair is damaged from chemical treatments, heat styling, or environmental exposure, Isoleucine aids in replenishing the protein content and restoring hair to a healthier state. This can help to repair split ends, frizz, and rough texture, leaving hair feeling smoother and looking shinier.

Isoleucine has a positive effect on moisture balance within the hair. It helps to lock in hydration, preventing hair from becoming overly dry or brittle. Well-moisturized hair is softer, shinier, and more manageable. By maintaining moisture levels, Isoleucine helps reduce frizz and enhances the overall appearance and texture of the hair.

Through its ability to strengthen and support the hair shaft, Isoleucine can contribute to the overall thickness and volume of the hair. Hair that is more resilient and less prone to damage can appear fuller and thicker, helping to create a more voluminous, healthy-looking mane.
