What type of proteins are specifically beneficial for hair strength?

Animal and plant-based proteins are particularly beneficial for hair strength because they contain essential amino acids that are vital for building and maintaining healthy hair structure. Hair is primarily made up of a protein called keratin, and incorporating high-quality proteins into your hair care regimen can help to strengthen and repair damaged strands.

Animal proteins, such as those derived from eggs, milk, and fish, often provide a complete amino acid profile that can enhance the hair’s tensile strength. These proteins can penetrate the hair shaft more effectively, helping to restore moisture and reduce breakage.

Plant-based proteins, found in sources like soy, quinoa, and wheat, also contribute to hair strength by providing important nutrients that support hair health and growth. They may also aid in maintaining hair's elasticity and moisture balance.

This choice stands out as it encompasses a variety of protein sources that work holistically to improve hair strength and integrity, making it the optimal choice among the options provided.
