If the night before was a late night, you may have the flu, or feel a headache coming, let’s postpone the session. Sitting under lights for 4 hours may make things worse. Short notice cancellation is perfectly fine; send me an email as soon as you know.If you have an unexpected sunburn (more than a mild suntan) or used self-tanner in the last 3 weeks, we should delay the session by at least 2 weeks.If you are on medication that you feel may have altered your colours, we might delay till you are well into recovery. In reality, our colouring rarely changes due to illness or medication, but to take full advantage of the session and the result, it may be best if you feel fully confident with your colours.
