Glutamic Acid
What is Glutamic Acid?
Glutamic Acid is a naturally occurring amino acid that's a building block of protein found in many plant and animal proteins. It is not typically synthesized for use; rather, it is extracted during the processing of protein-rich plant materials.
In hair care products, Glutamic Acid is used for its humectant properties, helping to retain moisture and improve the texture and manageability of hair. It is generally considered safe, and no adverse health effects have been linked to its use in hair care products.
When you see Glutamic Acid on a label, it is primarily there to enhance hydration or improve the product's feel and function on your hair.
