Does Olaplex No.5 Bond Maintenance Conditioner contain parabens, sulfates or fragrance?
A straight yes or no for the ingredient groups people most often want to avoid, checked against this product's published formulation.
Free from parabens
Preservatives; the longer-chain ones (propyl, butyl) carry the endocrine questions.
Free from sulfates (sls / sles)
Strong cleansing agents that can strip a compromised barrier.
Contains silicones
Found: divinyldimethicone/dimethicone copolymer, dimethicone peg-7 isostearate. Slip and occlusion; cyclic silicones (D4/D5/D6) are the environmentally restricted ones.
Contains fragrance / parfum
Found: fragrance (parfum). Undisclosed fragrance blends are the most common trigger for sensitised skin.
Contains essential oils
Found: limonene. Naturally derived, but among the most frequently reported contact allergens.
Free from drying alcohol
Fine in small amounts for texture; high up the list it can dehydrate.
Free from formaldehyde releasers
Preservatives that slowly release formaldehyde.
Free from chemical uv filters of concern
Restricted or debated filters with endocrine or reef-persistence questions.
Is Olaplex No.5 Bond Maintenance Conditioner non-comedogenic?
No ingredients in this formulation appear on Selenssa's common pore-clogger list, so it is unlikely to be the cause of congestion for most people. Comedogenicity is still individual — texture, occlusion and how much you use all play a part.
Is Olaplex No.5 Bond Maintenance Conditioner safe for sensitive skin?
Usually tolerated, but patch test if your skin reacts easily.
