Hair is primarily composed of a protein called keratin, which is made up of amino acids. These amino acids are essential for maintaining the structure, strength, and health of your hair. However, external factors such as heat styling, chemical treatments, and environmental stressors can lead to protein loss from the hair shaft.
When your hair lacks protein, it may exhibit signs of weakness, excessive breakage, limpness, or a mushy texture. In such cases, introducing protein treatments or products into your hair care routine can help reinforce the hair structure and improve its overall health.
Common sources of protein in hair care products include:
Keratin: A key protein in hair structure, and keratin treatments are popular for strengthening and smoothing hair.
Collagen: Helps improve hair elasticity and strength.
Amino Acids: The building blocks of protein; various amino acids can be found in hair care products to support hair health.
Silk Proteins: Known for their smoothing and strengthening properties.
