Olaplex
Reddit take
AI summary of the Reddit excerpts below — not a quote
Olaplex is widely recognized in hair care communities as a leading bond-repair treatment, particularly valued for restoring hair integrity after chemical damage like bleaching. While many users report significant improvements in hair strength, softness, and texture, the brand faces scrutiny regarding the lack of independent scientific verification for its specific chemical claims and reports of adverse effects from some users.
Pros
- Significantly improves hair tensile strength and extensibility in damaged fibers.
- Effective at making bleached or chemically treated hair feel healthy and 'normal' again.
- Users find it easier to integrate into existing routines and more affordable than some high-end competitors.
- Can enhance shine and define wave patterns when used as a treatment.
Cons
- Heavy formulas, particularly the No. 7 oil, can weigh hair down or contribute to an oily scalp if over-applied.
- Reports of hair breakage and damage, sometimes attributed to excessive or improper use.
- Mention of legal controversies and user concerns regarding potential hair loss.
Caveats
- Claims regarding the repair of disulfide bonds are primarily supported by company data rather than independent, peer-reviewed trials.
- Some cosmetic chemists remain skeptical of the brand's specific marketing claims.
- Proper dosage is critical; even a few extra drops of certain products can lead to greasy results.
Best for
- Chemically damaged or bleached hair requiring structural reinforcement.
- Users seeking a multi-step bonding routine (specifically No. 0 and No. 3).
Avoid if
- You have a very oily scalp and are prone to hair being weighed down by heavy oils.
- You prefer products with a high volume of independent, third-party clinical validation.

What redditors said (10 of 45)
The only thing that can be truly damaging are abusing bleach/hair dye, hair relaxers/perms, and things that chemically crosslink or change hair structure (Olaplex comes to mind).
If I’m not mistaken, Olaplex was (or still is) in a legal battle regarding their products causing hair loss (short and long term).
It is a good reminder though that neither Olaplex or K18 seem to have proven their products do what they claim to do. Also that they probably do *something* and do that something in a different way.
Olaplex^(®) showed superior thickness and the highest tensile strength and extensibility ([Figure 10](https://www.mdpi.com/2079-9284/11/5/150#fig_body_display_cosmetics-11-00150-f010)C–F), suggesting that the product may play a role in the core of the fiber, thus affecting the intrinsic mechanical properties.
the formula olaplex uses was still the best.

Olaplex, as far as I know, is good for chemical damage.
There isn't a lot of independent research to confirm that K18, Olaplex, and Epres do what they say they do in the hair.
Olaplex was the first bonding product on the market, and it was mainly Olaplex 3 that was intended to be used as a treatment for seriously damaged hair that works inside of the cortex. ... If you can afford it, and like what it does for your hair, then great; but it's not doing anything particularly special.
Olaplex and Redken ABC are different bond builders that you could try (why not both?).
