Hair bonds are the foundation of everything your hair stands for—strength, texture, and resilience. But what exactly are bonds in hair, and why should you care? In the world of hair science, understanding these microscopic connections can change the way you care for your mane, giving you healthier, more radiant locks. Let’s break down the science, reveal what breaks those bonds, and show you how to repair and protect them like a pro.

 

WHAT ARE BONDS IN HAIR?

Think of hair bonds as the invisible superglue that holds your hair’s structure together. These chemical connections inside your hair strands keep everything intact—shape, strength, flexibility. The three key players are:

  • DISULFIDE BONDS: The strongest of the bunch. Formed between sulfur atoms in keratin, these bonds shape your hair and give it lasting strength. When you color, perm, or relax your hair, you’re actually breaking and reforming these powerful bonds.
  • HYDROGEN BONDS: These are the quick-change artists—forming and breaking with water or heat, they control temporary styles like curls or straightened strands.
  • SALT BONDS: Sensitive to pH and moisture, these ionic bonds help keep your hair’s structure stable day-to-day.

Together, they make your hair uniquely you—strong, flexible, and ready for any style.

Hair bonds aren’t invincible; they’re vulnerable to damage from everyday stresses. Here’s what throws a wrench in the works:

  • CHEMICAL SERVICES: Coloring, bleaching, or perming? These treatments break disulfide bonds to reshape hair but can leave it compromised if not properly cared for.
  • HEAT STYLING: Flat irons and blow dryers are fun but blast hydrogen bonds and weaken your cuticle when overused.
  • ENVIRONMENTAL ASSAULT: UV rays, pollution, and harsh weather conditions chip away at your hair’s natural defenses.
  • MECHANICAL DAMAGE: Rough brushing, tight ponytails, and aggressive towel drying put stress on bonds and cause breakage.
  • WRONG PRODUCTS & CARE: Sulfate-heavy shampoos and skipping conditioning treatments strip hair of vital moisture and weaken bonds.

Know the enemy to protect your hair better—damage to hair bonds is the root of dullness, breakage, and frizz.

 

HOW TO STRENGTHEN AND REPAIR HAIR BONDS

Here’s the good news: modern hair science is on your side. Strengthening and repairing hair bonds is possible with the right arsenal:

  • BOND-BUILDING TREATMENTS: Look for bond builders packed with Citric Acid, which helps strengthen damaged hair such as the Redken Acidic Bonding Concentrate Intensive Treatment that helps provide pH balance, strength, and conditioning with a bonding care complex formula. You can expect strength repair for dry, damaged hair. Using this system results in 2x stronger* and 90% more conditioned* hair. It also provides instant results in 5-10 minutes, repairing hair strength inside and out for 14x smoother hair* and 63% less breakage*.
  • HYDRATING CONDITIONERS:Moisture is the MVP to preserve hydrogen and salt bonds, keeping hair soft and flexible. Redken’s All Soft Conditioner made with 5% of Redken's Moisture Complex and Argan Oil, All Soft Conditioner is prescribed for hair requiring moisture, an essential component to healthy-feeling hair.
  • PROFESSIONAL BOND REPAIR: Treatments inspired by cutting-edge technology rebuild bonds at the molecular level for stronger, healthier hair.
