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.
