What is a hair bond?

Hair bonds are essential to the structure of your strands. While keratin proteins mostly comprise individual , chemical hair bonds are what hold these keratin proteins together.

“There are actually three types of hair bonds; each behaves differently and serves a different purpose in building the structure of the hair,” Welsh explains. “They are responsible for the hair’s shape, strength, elasticity, and shine.”

Because bonds affect the look and feel of your strands, it’s important to have strong bonds in your hair.

What are the different types of hair bonds?

As Welsh explained above, there are three different types of bonds, each contributing a unique purpose to the . The stylist breaks down exactly what each bond does:

  • Hydrogen Bonds: These bonds allow you to manipulate your hair's look and feel temporarily.
  • Ionic Bonds: Sometimes also known as salt bonds, these are temporary bonds that contribute to the strength and elasticity of hair.
  • Disulfide Bonds: These are strong permanent bonds that help determine the shape and structure of your strands.

What breaks bonds in the hair?

Much like each type of bond has a distinctive purpose, different things may cause each bond to break. Hydrogen and ionic bonds are temporary, making them the easiest to break. Welsh says hydrogen bonds can be damaged by heat and water, which is why it’s easier to manipulate your hair when wet or when you heat style your hair. When exposed to those elements, these broken bonds also make your hair more fragile. Changes to the in your hair can break ionic or salt bonds. Disulfide bonds are permanent and, therefore, much harder to break.

“Disulfide bonds are broken down by chemicals like coloring, services, and relaxers or ,” says Welsh.

While hydrogen and ionic bonds can be easier to repair, disulfide bonds require much more preventative and reparative care. This is why we always suggest heading to a salon professional for chemical services like hair coloring and perms. Your stylist will do their best to prevent and repair damaged bonds and send you home with an at-home hair care routine.

How can you tell if your hair needs bond repair?

There are so many on the market, but how do you know if your hair needs bond repair specifically? The truth is that if you are dealing with any hair damage, your strands are likely in need of bond repair. If your hair looks and feels rough, dull, dry, brittle, or broken, your mane may benefit from bond-repairing products.

“Your hair will need bond repair after , a chemical service like straightening or perming, using , or if your hair is brittle and weak,” Welsh explains.

If you are unsure whether your hair can benefit from bond repair, schedule an appointment with a stylist and allow them to guide you.

How do you strengthen and repair bonds?

Okay, so you know what hair bonds are, what breaks them, and how to identify whether they need repair—so how exactly do you strengthen and repair the bonds in your hair? There are several bond repair products on the market, but we’re partial to Redken’s Acidic Bonding Concentrate range.

“Redken’s ABC line is formulated to help reinforce weakened bonds and provide strength repair,” Welsh explains. “This line is a repair system starting with a , , Conditioner, and , which is formulated with a heat protectant up to 450 degrees Fahrenheit to further protect against broken bonds.”

The Redken Acidic Bonding Concentrate system is made with citric acid, an alpha-hydroxy acid often found in popular skincare products and the brand’s Bonding Care complex. These ingredients reinforce weakened bonds to help build your hair’s strength and resiliency. The range defends against the damaging effects of chemical services, styling tools, and even while also helping to rebalance your mane’s natural for healthier-looking, stronger hair. The is the latest addition to the range. It’s perfect for anyone seeking a bond repair product that won’t weigh your hair down, especially those with fine hair types.

Welsh recommends Redken if you’re not looking to switch up your entire hair care routine but need some quick and easy bond repair.
