There is no link between colouring hair and problematic pregnancy, however it is advisable to:

• Not colour the hair for the first 12 weeks of pregnancy.
• Avoid hair colouring having contact with the scalp.
• If colouring, do so in a well-ventilated area.
• Always carry out a strand and patch test as during pregnancy hormonal imbalances can occur, resulting in different colour results to those you may be expecting.
