Protein treatments are very important elements for our hair nutrition.
The cuticle, which is the top layer of hair formed by different layers of cells. The cuticle is responsible for about 30% or our hair strength andhe cortex give us about 70%. The cuticle should remain closed in order to protect our hair from damage and breakage. From the moment our hair is expose to, keratin straighteners, excessive use of heat, relaxers, texturizers and other related chemicals, the cuticle becomes weak and some times extremely damaged ‘in this case, the cuticle can not protect our hair cortex and becomes vulnerable to dehydration causing hair breakage and hair loss’
The hair cortex, is what gives us fine or thick hair texture as well as the strength and color, “African American Hair Cortex is very small, much smaller than other races and is more prone to breakage"
The Medulla is the deepest or last layer of the hair, the medulla helps to expel un-wanted substances or damaging chemicals also helps to retain the moisture our hair needs to remain healthy and grow. The main function of the medulla is not completely known and only people with thick hair have a medulla.
Note that some protein are stronger than others, we must be careful. The constant use of strong protein treatments can dehydrate your hair and cause more harm than good.

Avoid Protein excess on natural hair.
Natural hair does not need a high level of protein unless your hair is often exposed to heat or permanent hair colors. Excessive use of protein could cause dehydration, breakage and severe hair loss. Avoiding products that contain high levels of proteins could be the key to keep your hair soft and curls defined.
There are different types of hair products; some are based in protein and some are based in moisturizers. Although protein treatments contain some levels of moisturizes, the basic ingredient is protein.
We should have a reason to use protein on our hair. For example, it is good to treat your hair with the right level of protein one week before and the week after flat ironing, relaxing, bleaching or any other chemical procedure.
