What causes protein loss in hair?

Daily exposure to aggressors like heat styling, chemical treatments, and environmental factors all contribute to protein loss. This depletion can leave hair feeling dry, coarse, and looking dull or frizzy.

What is the main protein that makes up hair?

While hair contains over 50 different types of proteins, the vast majority of it is comprised of keratin. This protein is what keeps the hair shaft protected from the stress of everyday life.

What is proteomics in hair care?

Proteomics is a science that involves mapping the structure of hair's proteins. This process makes it possible to identify exactly which proteins have been depleted from the hair due to damage.

The Role of Protein in a Healthy Hair Regimen

Your hair is exposed to daily aggressors, including heat styling, chemical processes, and environmental factors, which contribute to protein loss. This can leave hair feeling dry, coarse, and frizzy, or appearing dull. At Nexxus, we utilize Proteomics—the science of mapping hair's protein structure—to identify which proteins have been depleted. This allows us to create ProteinFusion blends with precious ingredients from nature, helping you achieve a good hair day, every day.

Hair is composed of over 50 different types of proteins, with keratin being the primary component that protects the hair shaft from stress. Through Proteomics, we understand that damage repair is not a universal solution. Different processes cause the loss of specific proteins, leading to distinct types of hair damage that require targeted care.

While a small amount of keratin loss occurs naturally over time, this process is accelerated by heat styling, chemical treatments, and pollution. Without the proper protection or repairing treatments, hair can become compromised and weakened.

To prepare hair for a drastic colour change, you can use a damage healing mask containing keratin protein to strengthen the strands. Following up with a reconstructing treatment can also help add protein back into your hair, getting it into top shape.

No, repairing hair is not a one-size-fits-all process. Different types of damage, such as from heat or chemical treatments, cause the loss of specific proteins, which in turn creates different types of damage requiring targeted solutions.

Yes, everyone naturally loses small amounts of keratin from their hair over time. However, this loss cycle is significantly accelerated by heat styling, chemical salon processes, and pollution, which can compromise and weaken hair.

Through Proteomics, our scientists have identified how and why protein loss happens — developing products that can help replenish the strength, shine, and vibrancy your hair was meant to have.

The reason for the change was fairly simple. Stars (they're just like us) also get bored with their hair colour! "I recently cut my hair, and thought 'I just want the exact opposite of what I have," Leighton said. "I want to try something completely drastic and different, and I thought this is the right moment to do it. You know when you just get it in your mind and you have to do it?" To get her hair in top shape for the new hue, Leighton used Nexxus Keraphix Damage Healing Mask ($5), which contains Keratin protein to strengthen the strands, and Keraphix Damage Healing Hair Reconstructing Treatment ($15) to add protein back to her hair.
