What matters most
- The required product, method and interval depend on the intended treatment system.
- Changing product, health history or the time since a previous test may mean another test is needed.
- A negative patch test does not make it safe to ignore symptoms during or after treatment.
Why the appointment must be planned
Tinting, lifting and lamination use different products. A patch test for one product or service should not be assumed to cover every other one. The salon must know the intended appointment before confirming what testing is required and when it should be completed.
Book early enough to complete the relevant protocol. Turning up on the treatment day without a required test can mean the service must be postponed.
Information to disclose
Tell us about previous reactions to hair dye, tint, adhesives, lifting products or cosmetics around the eyes and brows. Also mention a current rash, broken skin, eye irritation or a health change that may affect the appointment.
- Do not test over broken or already irritated skin.
- Do not conceal a previous reaction because a later appointment seemed fine.
- Record any symptoms and when they appeared after the test or treatment.
What a patch test cannot promise
A small test exposure is not identical to a full treatment, and sensitivity can change over time. Continue to speak up if burning, unusual discomfort or irritation develops during the service.
If symptoms become significant or continue to worsen, stop using cosmetic products on the area and seek healthcare advice. Severe rapidly developing swelling or breathing difficulty is an emergency.
Common questions
Before you book
How long before my treatment is a patch test required?
The timing depends on the product instructions and salon protocol. Contact us with the exact service so we can confirm the correct interval.
Does my old patch test cover a different tint brand?
Do not assume it does. Product changes and elapsed time can affect the salon's requirements.
Can a reaction happen after a negative patch test?
Yes. A patch test reduces uncertainty but cannot guarantee that no reaction will occur during or after a full service.
