Client Consultation and Diagnosis
Core concepts
Consultation is a structured conversation plus observation. Learn the hair and scalp analysis sequence: scalp condition (dry, oily, flaky, sensitive, lesions), hair density, texture, porosity, elasticity, and the hair's growth pattern (cowlicks, whorls). Understand porosity (how readily hair absorbs moisture) and elasticity (whether wet hair stretches and returns), because both drive product and chemical choices.
Know how to run a patch test for colour products and a strand test before chemical services, and why both matter. Understand contraindications to chemical services: recent henna or metallic salts, active scalp infection, open wounds, very recent lightening, pregnancy (advise medical consultation for some services), and known product allergy. Know client records: consent, history, products used, timings, results.
Communication skills are tested: open and closed questions, active listening, clarifying expectations, managing unrealistic goals, and explaining risks and aftercare. Know how to identify hair loss patterns at a basic level and when to refer to a medical professional rather than treat in salon (sudden loss, scarring, scalp disease, unexplained thinning).
Traps
Questions often present a client with a scalp lesion and expect you to proceed with a colour service; the correct answer is to defer or refer. Another trap is confusing a patch test with a strand test.
Rule of thumb
No diagnosis, no service: if you cannot explain what you observed and why it changes your plan, you are not ready to begin.
