Fragrance formulas are extremely complex and can consist of hundreds of ingredients, so even if a product is labelled as fragrance-free you can still be exposed to fragrance ingredients. Oftentimes these ingredients are use as preservatives or used as an active in the formula.
Fragrance-free products cannot contain ingredients that are normally used to transmit a scent; however, a fragrance-free product may contain essential oils like tea tree and lavender. These oils often contain medicinal properties which is why they could be included in the formula. They most likely will not be listed as fragrance however, they can cause a reaction if they are used at high levels.
