Bond-building haircare 101: The science of repairing damaged hair

Bond-building treatments are a major focus in haircare, renowned for their ability to repair damage. Whether your hair is dry from coloring, prone to breakage from heat styling, or sun-damaged, a bond builder can help. For instance, a bond-building shampoo or mask can restore hair health. The secret to how these products work on various hair issues lies in a key ingredient: amino acids.

Key takeaways

The science of repair: Bond-building treatments use amino acids, the building blocks of hair protein, to repair damage from coloring, heat, and other stressors at a molecular level.
Internal vs. surface treatment: Unlike products that only coat the hair's surface, amino acid-based formulas like the Nexxus Amino Bond range penetrate the hair fiber to rebuild broken bonds from within.
Visible results: Consistent use leads to stronger, smoother, and more manageable hair with fewer split ends, as the hair's internal structure is genuinely repaired.
Suitable for all damaged hair: While especially transformative for severely damaged hair, bond-building products benefit anyone experiencing breakage, frizz, or dullness.

How are amino acids and hair related?

Amino acids are the fundamental building blocks of protein. In hair, 23 amino acids bond together to form the keratin protein that makes up 90% of every strand. These amino acids determine hair's strength, shape, and shine. When hair is damaged, these crucial hair bonds can break, leading to a loss of amino acids. This results in visible signs of damage like breakage, frizz, and dullness.

How can amino acids in haircare help?

Nexxus bond-building products leverage amino acids to repair hair. These powerful molecules work to rebuild broken bonds and generate new ones within the hair fiber. Unlike products that only treat the hair's surface, the Nexxus Amino Bond range uses the power of amino acids to penetrate deep into the hair's internal structure, healing and strengthening from within.
