1. What is chemical sensitivity & mcs in salons?

Key Terms in This Article

INCI: International Nomenclature of Cosmetic Ingredients — standardized naming system for cosmetic ingredient labeling.
Adverse Event: An undesirable health effect reasonably linked to cosmetic product use, requiring mandatory reporting under MoCRA.

Multiple Chemical Sensitivity (MCS) and fragrance sensitivity affect an estimated 2-6% of the population^[1]. For these clients, a standard salon visit — with its cocktail of ammonia, peroxide, fragrances, and aerosols — can trigger headaches, respiratory distress, or dermatitis. Creating a low-chemical or fragrance-free service option is both an inclusion measure and a market differentiator^[2].
