According to the NHS, professional hair colouring is generally considered safe during pregnancy. That said, there are a few things worth being aware of before booking your appointment.
What the Research Says
- Low Absorption: Research shows that very little of the chemicals used in professional hair colour are absorbed into the body, and the amounts are considered too low to cause harm.
- Some Wait Until After the First Trimester: While not a formal medical guideline, some clients prefer to hold off until after the first 12 weeks as a personal precaution.
Sensible Precautions
- Ventilation Matters: All colour services are carried out in a well-ventilated space, which helps limit exposure to any fumes.
- Sensitivity Can Change: Hormones can affect how your scalp or skin reacts, so a patch is always done beforehand—especially important during pregnancy.
- Minimising Contact: Techniques like balayage or highlights can help reduce direct contact with the scalp if that’s a concern.
Product Choices
- Gentler Formulations Available: If you’d prefer to avoid certain ingredients, just ask—there are alternative products and methods that can be used.
- Tailored Colour Choices: Semi-permanent or tone-on-tone colours are also available, depending on what you’re comfortable with.
If you’re unsure, it’s always a good idea to speak to your GP or midwife before your appointment. Your comfort and safety are the top priority, and everything can be tailored to what feels right for you.
