Does Olaplex No.3 Hair Perfector 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.
Free from silicones
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.
Free from essential oils
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.
