Henna products contain ingredients that may cause skin irritations or allergic reactions on some individuals. A patch test must be performed at least 48 hours prior to treatment. This may also be a requirement of your insurer.

How to do a patch test

•          Use soap and water to cleanse a small area of skin behind the ear or on the inner surface of the forearm.

•          Follow the preparation instructions for your brand and mix a small amount of tint & developer together.

•          Apply the tint to the area you have prepared on your client.

•          The client should leave the products on their skin for 48 hours and then remove with soap and water.

•          If there is no irritation or inflammation in the area, then it is assumed that there is no hypersensitivity to the products.

A negative result on a patch test does not mean that the client will not react during treatment.

Patch tests should be performed regularly especially where clients may have not visited the salon in 6 months or had a change in health or medication. Sensitivity can occur at any point. If reaction occurs, then remove the product immediately and wash the area with water. Seek medical attention for your client.
