Distilled from the video reviewers — the score, what they praise, where they push back.?

No. 4 Bond Maintenance Shampoo
3.0/5
divided
Reviewers praise
  • Repairs broken disulfide bonds when used with the full treatment system
  • Sulfate-free formula is color-safe and works across all hair types
  • Noticeably reduces breakage and strengthens hair structure over time
Reviewers push back
  • Heavy residue makes hair feel oily and dirty faster between washes
  • Small bottle size depletes quickly, especially on long or thick hair
  • Works poorly as a standalone shampoo without the treatment system
when I was rinsing my hair within one use, my hair actually felt thicker at the ends, and it also felt significantly smoother
Audrey Victoria · best for People with severely damaged hair from bleach or chemical treatments who will use it as part of the full Olaplex repair system, not as daily maintenance.
No. 5 Bond Maintenance Conditioner
3.0/5
divided
Reviewers 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
Reviewers push back
  • 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
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.
— best for: 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.

I was a little skeptical at first because I’ve tried so many strengthening shampoos that either left my hair flat or too dry, but this one really surprised me. From the very first wash, my hair felt clean without being stripped, and it actually had a little extra bounce once it dried. It doesn’t weigh my hair down at all, which is a big win for me.

Suitability for fine/thin hair4.4
I’ve been using Olaplex No.5 Conditioner along with No.3 and No.4, and I honestly feel like my hair routine has changed for the better. I have very thin, fragile hair that tangles easily and sheds a lot. Most conditioners either leave my hair flat and greasy or don’t hydrate enough. This one feels like the perfect balance – nourishing, but still lightweight. Packaging: Minimal and sleek, matches t Hafsa S · influenster.com
