Quick Answer
In-depth analysis of contraindication checklist within client health screening & consultation for salons.
Modernization of Cosmetics Regulation Act — 2022 US law requiring FDA registration and safety substantiation for cosmetics.
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.
A thorough client consultation is both a legal duty of care and the foundation of personalised service[1]. Pre-service screening identifies contraindications — allergies, medications (isotretinoin, anticoagulants), pregnancy, scalp conditions (psoriasis, open wounds), recent chemical treatments — that alter service safety[2].
This deep dive focuses on contraindication checklist — one of the most critical sub-areas within client health screening & consultation.
2. Common pitfalls
Screening questions asked verbally, not documented
Contraindications (isotretinoin, anticoagulants) not in screening checklist
Pregnancy chemical restrictions unknown to junior staff
Previous adverse reactions not recorded in client file

4. Operator dialogue
🦉 & 🐥 & 🐮 — Salon operator dialogue
🐥
Piyo: Poppo, what should a salon consultation card actually ask?
🦉
Poppo: Allergy history, current medications, skin conditions, pregnancy status, previous adverse reactions to salon products, and any metal implants (for certain electrical treatments). The goal is to identify contraindications before you start, not discover them during service.
🐥
Piyo: Is verbal screening enough?
🦉
Poppo: No. A documented consultation card is a legal record. If a client has an adverse reaction and you can show you screened for it, documented the answer, and proceeded appropriately, you have a defence. Verbal-only screening is invisible — it might as well not have happened.
🐮
Mou: Strong, kind, beautiful — asking the right questions before you start is the kindest thing a professional can do.
