It is crucial that hair remains in its natural state until you return after 3 days for the follow up treatment. Results are only guaranteed when the following points are adhered to:

Keep your hair dry.
Don’t allow hair to become wet until you have been for the follow up appointment.
Do not use spectacles to hold your hair back or tuck hair behind your ears.
Do not use any devices such as grips to tie your hair back.
Only use the approved shampoo and conditioner provided.
