why should we use protein treatments?

Hair products generally fall into two categories: protein-based and moisture-based. While many moisturizing formulas include small amounts of protein, the defining characteristic of a protein treatment is its ability to rebuild, strengthen, and support overall hair health and growth. 

Your hair is composed primarily of keratin, a fibrous protein. It is divided into two primary sections:

The Cuticle: The outer, shingle-like layer formed by overlapping cells. It accounts for about 10–30% of your hair's overall strength . To protect the inner structure from damage, the cuticle must remain smooth and closed.

The Cortex: The inner core of the hair shaft that provides the remaining 70–90% of your hair's strength and elasticity .

The hair cortex is the middle and thickest layer of the hair strand, determining both hair texture (fine or coarse)  and color . In many cases, African, Afro-textured, and curly hair types have a flatter, more irregular cortex . This structural shape means it is smaller and more fragile, making the hair more prone to dryness and breakage .

The medulla is the innermost or deepest layer of the hair shaft . It acts as the soft core or "marrow" of the hair. While its exact biological purpose in humans is largely a mystery , it is thought to provide some structural reinforcement to the hair strand.

Unlike the cuticle and cortex , the medulla is not present in all hair types . It is primarily found only in thicker, coarser hair strands , and is often completely absent in fine hair  or naturally light blonde hair

How Damage Occurs

When hair is frequently exposed to keratin straighteners, relaxers, texturizers, bleach, or excessive heat styling , the cuticle becomes weak and porous. In this damaged state, the cuticle can no longer protect the vulnerable cortex, leading to severe dehydration, brittleness, breakage, and hair loss .

 Relaxers and bleach work by breaking the hair's internal bonds, stripping away essential proteins. Therefore, relaxed or color-treated hair requires consistent, restorative care. 

Implementing protein-rich products into your hair care regimen is highly recommended, especially after chemical services . Here is the restorative routine that has worked successfully for my clients for years.

Natural vs. Chemically Treated Hair

Natural, virgin hair does not require heavy protein treatments unless it is frequently exposed to heat or permanent hair color. In fact, avoiding heavy protein products can be key to keeping natural curls soft and defined. 

However, even natural hair can benefit from a balanced protein treatment about once a month to maintain optimal health and support continuous length retention.
