AI summary of 5 reviews · as of May 2026

Reviewers agree the conditioner works as a bonding treatment but most find it lacks the hydration damaged hair actually needs, making it feel incomplete for its price tier.

Where reviewers disagree: Some reviewers felt the conditioner was better than the shampoo, while one professional found both equally lacking in hydration; One reviewer noticed significant smoothness and thickness after use, while others reported minimal noticeable improvement; Disagreement on whether the shampoo-conditioner duo is necessary at all versus just using Number 3 treatment

Reviewers split

What they praise

  • Contains the patented bond-building technology found across the Olaplex line
  • Thick, luxurious texture that feels like a treatment experience
  • Works well when paired with the full system, especially Number 0 and Number 3
  • Pleasant scent that reviewers consistently enjoyed

What they knock

  • Lacks sufficient hydration for damaged hair that needs both strength and moisture
  • Heaviness causes buildup and makes hair feel oily or dirty faster
  • The shampoo leaves a residue layer that some users can feel on their hair
  • Not suitable for anyone without damaged hair—no benefit for healthy strands

Who reviewers think this product is — and isn’t — for

For you if

People with chemically damaged hair, especially from bleaching or highlights, who are already using the Olaplex treatment system and want to maintain salon bond-building results at home.

Look elsewhere if

Anyone with fine hair, healthy undamaged hair, or those seeking hydration and moisture rather than pure bond repair—and anyone not willing to wash more frequently due to heaviness.

Frequently asked

What buyers want to know.

  • What are the benefits of Olaplex No. 5 Bond Maintenance Conditioner?

    It contains Olaplex's patented bond-building technology to repair and maintain chemically damaged hair. Reviewers note it has a thick, luxurious texture and works best when paired with other products in the Olaplex system. However, most reviewers find it lacks the hydration that damaged hair actually needs.

  • How to use Olaplex No. 5 Bond Maintenance Conditioner?

    Reviewers found it works best as part of the full Olaplex system, especially when used alongside Number 0 and Number 3 treatments. It should be used more frequently than standard conditioners because its heaviness can cause buildup.

  • Who is this conditioner best for?

    It is designed for people with chemically damaged hair from bleaching or highlights who are already using Olaplex treatments and want to maintain results at home. It is not suitable for anyone with fine, healthy, or undamaged hair, or those looking mainly for moisture and hydration.

  • Why did people stop using Olaplex?

    Reviewers report that the conditioner and shampoo can feel heavy and cause buildup, making hair feel oily or dirty faster. Some questioned whether the shampoo-conditioner duo is necessary at all, preferring to use just the Number 3 treatment instead.
