Here are essential instructions on how to conduct a patch test before your eyebrow-dyeing treatment. This step is crucial in identifying any potential allergies, even if you’ve used coloring products before:
- Prepare the Mixture: Mix 2 parts Liquid Dye with 1 part Oxydant.
- Application: Apply a small dot of the mixture behind your ear.
- Timing: Rinse the area with water after 15 - 20 minutes.
Please be aware that if you experience any itching, redness, burning, rash, swelling, blistering, skin weeping, or shortness of breath during the test or within 48 hours afterward, it’s important to refrain from proceeding with the Liquid Dye with Keratin treatment. Keep in mind that a patch test does not guarantee you won't develop an allergy; sensitivities can arise over time.
