The useful distinction
What fits—and what remains unknown.
Who might compare it
Shoppers with medium-to-coarse hair who are comfortable with fragrance and want to compare a concentrated formula.
Consider before choosing
Contains the brand's signature scent; not the fragrance-free choice on this list.
Brand-published facts
- OLAPLEX positions this shampoo for medium-to-coarse hair and lists a 250 ml full size.
- The brand says it is color-safe and free of SLS/SLES sulfates.
- Its official page describes a grapefruit, mint, ginger and sage scent profile.
These statements summarize the brand page; they are not our measured results.
Our shopping judgment
The clearest contrast to the two fragrance-free picks: assess texture and scent preference before brand claims about repair.
An editorial interpretation of published information, not a personal-use test.
Not independently verified
