It is critical that you carry out a patch test at least 24 hours before the HD Brows treatment. Although it is rare – this is to ensure that you do not have an allergic reaction to the tint used. Ideally it is best to pop into the salon, alternatively a sample can be sent by post.
A signature will be required to state that you have carried out the patch test before the treatment. Unfortunately if you have not completed the patch test, the treatment will not be carried out and you may be charged.
