L'Oréal Paris Bond Repair for Damaged Hair

Hair is made up of millions of bonds that give it structure and strength. When those bonds break through brushing, bleaching, heat and styling, hair becomes weak, damaged and more likely to snap. L'Oréal Paris Bond Repair is a Hair Expertise range made to rebuild those inner broken bonds. Powered by citric acid, it works from the inside out to strengthen hair and help prevent breakage, and it is suitable for all types of damaged hair. Shop the four steps in the grid above.

What Is a Bond Repair Treatment?

A bond repair treatment targets the inner structure of the hair fibre rather than only coating the surface. That makes it different from a regular conditioner or mask, which mainly smooths the outside of the hair. Bond Repair starts before you shampoo: the pre-shampoo treatment oversaturates the hair with citric acid to rebuild broken bonds, and the following steps strengthen, seal and protect the lengths.

The 4-Step Bond Repair Routine

Step 1: Bond Repair Rescue Pre-Shampoo. Apply a generous amount to damp hair from scalp to ends, leave on for five minutes and rinse. For optimal results, use it once a week.

Step 2: Bond Repair Sulfate-Free Shampoo, the second and most important step of the routine.

Step 3: Bond Repair Conditioner seals in the cuticles for maximum care. Apply it from lengths to tips, leave on for three minutes and rinse.

Step 4: Bond Repair Leave-In Serum protects hair bonds from breakage and adds shine and heat protection. Rub two drops between your palms and apply through the lengths and ends of wet or dry hair.

Used together, the pre-shampoo, shampoo and conditioner give up to 98% less breakage in instrumental tests, and the serum gives up to 12x fewer split ends.

Signs Your Hair Needs Bond Repair

Damaged bonds often show up as hair that snaps when you brush it, short broken pieces around the crown and hairline, more split ends, or lengths that feel rough and look dull. These signs are common after bleaching, frequent colouring or regular use of hot tools. If your hair mainly needs smoothing or nourishment rather than repair, compare Total Repair 5, see whether keratin treatments are worth the hype, or browse every L'Oréal Paris shampoo.

Which Bond Repair Product Do You Need?

If your hair is breaking or feels weak after bleaching or heat styling, start with the full routine, including the weekly pre-shampoo. If you want daily care between treatments, the shampoo and conditioner can be used as often as needed. If split ends and frizz are your main concern, add the Leave-In Serum after every wash, on wet or dry hair.

Bond Repair or EverPure Bond Repair+?

L'Oréal Paris has two bond-strengthening lines, so it helps to know the difference. Hair Expertise Bond Repair, on this page, is a 4-step routine built around citric acid and a weekly pre-shampoo treatment. EverPure Bond Repair+ Shampoo belongs to the sulfate-free, vegan EverPure line for colour-treated hair. Choose Hair Expertise Bond Repair for intensive repair of damaged hair, and EverPure if keeping your colour vibrant is the priority.

Help Prevent Hair Breakage

Repair works best alongside gentler habits: detangle from the ends up, turn down the heat on hot tools and give your hair time between bleaching sessions. Long hair with split ends may also benefit from Dream Lengths, and dry, dehydrated hair from Hyaluron Plump.
