Hair salons are among the most chemically intensive workplaces in the personal care industry. A typical salon uses hair colorants containing oxidative dyes, bleaching agents with hydrogen peroxide, permanent wave solutions with thioglycolate, keratin treatments, styling products, and a range of shampoos and conditioners — each with its own formulation of active and inactive ingredients.
Salon professionals apply these products repeatedly throughout the day, often with direct skin contact. Clients receive these products on their hair and scalp, sometimes for extended contact periods during processing. The cumulative chemical exposure for both professionals and clients makes ingredient verification particularly important in this setting.
Hair colorants alone may contain p-Phenylenediamine (PPD), resorcinol, hydrogen peroxide, ammonia, and various coupling agents — all of which are regulated substances under EU Regulation 1223/2009 with specific concentration limits and mandatory warnings.
MmowW's free Ingredient Checker allows hair salon professionals to verify product ingredients against regulatory databases. Enter the INCI names from any product label, and the tool identifies substances that are prohibited, restricted, or subject to conditions of use.

A freelance colorist working across multiple salons checks the products available at each location. The tool identifies that two salons use different versions of the same brand — one sourced from within the EU and one from a non-EU supplier with a different formulation containing an ingredient not permitted in the EU market.
Q: Are hair colorant ingredients regulated differently from other cosmetic ingredients?
A: Yes. Many oxidative hair dye substances have specific entries in Annex III of EU Regulation 1223/2009 with conditions that apply only to hair products, including concentration limits and mandatory warnings specific to hair coloring.
Q: Should I check professional-use products that are not sold to consumers?
A: Yes. Professional-use products are still cosmetic products under EU and US regulations. Some professional products contain higher concentrations of active ingredients, making ingredient checking particularly important.
Q: Can the tool check ingredients in products I mix in the salon?
A: Yes. If you mix color formulations, enter the combined ingredient list to check that your custom blend does not create a formulation that exceeds regulatory limits.
