How to establish client consultation and allergy patch testing procedures

To protect your business and your clients, you must implement a mandatory policy where no chemical service is performed without a successful Allergy Alert Test (AAT) conducted at least 48 hours prior. Documenting every consultation and test result is essential to comply with your professional insurance and UK health and safety standards. Without these records, your insurance may be void in the event of a claim.

The art of the client consultation

A consultation isn't just a friendly chat; it's a vital risk-assessment and goal-setting session. It allows you to manage expectations and identify any potential contraindications before you even pick up a brush. For every new client, and at regular intervals for returning ones, you should discuss:

• Hair History: Previous colours, chemical treatments (like perms or relaxing), and the use of home box dyes.
• Lifestyle: How often they wash their hair, their use of heat tools, and exposure to chlorine or sun.
• Desired Outcome: Use visual aids (like Pinterest or a shade chart) to ensure you are both on the same page.
• Scalp Health: Check for abrasions, sores, or irritation, as chemical services should not be performed on broken skin.

The Allergy Alert Test (AAT) procedure

Commonly known as a "patch test," this is the process of applying a small amount of the professional product to the skin to check for a reaction. Follow these steps to ensure compliance:

1. Timing: Perform the test at least 48 hours before the scheduled colour appointment.
2. Application: Apply a small amount of the specific tint and developer (mixed according to manufacturer instructions) behind the ear or in the crook of the elbow.
3. Observation: Instruct the client to leave the product on for the duration specified by the manufacturer (usually 45 minutes) and then wipe it off. They must monitor the area for the full 48 hours.
4. Reaction: If any redness, itching, or swelling occurs, the service must not proceed.

Documentation and record keeping

In the eyes of an insurer, if it isn't documented, it didn't happen. You must keep a digital or physical "Client Record Card" for every individual. This should be updated every time they visit.

Information to Record	Why it matters
Date of AAT	Proves you followed the 48-hour safety window.
Product Batch/Brand	Ensures the test was performed with the specific brand used.
Client Signature	Confirms they understand the risks and have provided honest history.
Consultation Notes	Details of hair condition and agreed-upon service.

Tips for best practice

Following industry standards not only keeps people safe but also builds your reputation as a professional expert.

• Follow Manufacturer Guidelines: Every colour brand has slightly different AAT protocols. Always follow the specific instructions provided with your chosen product line to stay within the terms of your insurance.
• The "Six-Month Rule": Even for regular clients, you should repeat the AAT every six months, or sooner if they have had a change in health, a new tattoo, or if you switch colour brands.
• Go Digital: Consider using salon management software that allows clients to sign digital consultation forms. This makes searching for records much easier than sifting through paper files.

Pro Tip: Never be afraid to refuse a service if a client refuses a patch test. It may feel like losing a sale, but it protects you from a potentially life-changing legal claim and protects the client from a severe allergic reaction.
