Pregnancy may make you feel a bit of a hot mess, but the ‘pregnancy glow’ is a real thing.

Is it safe to dye your hair during pregnancy?

Hooray! The official consensus is yes, using hair dye when pregnant is safe.

This is because the hair dye just doesn’t stay in contact with your skin long enough to enter your bloodstream in a way that is harmful to your growing bean.

Although hair dye contains chemicals, they aren’t in high doses or large enough amounts to be in any way dangerous to your baby.

Will my hair change when I’m pregnant?

Remember that pregnancy can also affect your hair’s normal condition. This is often a good thing!

You might find your hair appears thicker and glossier. You won’t find as many hairs in the plug hole either!

Your hair will fall out less thanks to those baby-growing hormones, which is also why it seems thicker.

Hormone changes may mean that dyes don’t necessarily affect your hair in the same way, so using hair dye when pregnant may not give the results that you’re used to, even if you use the same old trusty dye you’ve always used before.

It’s also always a good idea to do a patch test first to check for any adverse reactions to any new hair colour.

When can I start using hair dye in pregnancy?

There’s no hard and fast rule as to when you can start dyeing your hair while pregnant.

Many women wait until after 12 weeks of pregnancy (after the first trimester), when the very low risk of the chemicals harming the baby is even lower. 

What is the safest hair dye to use?

If you are hesitant to use regular hair dyes during pregnancy, there are some safer alternatives to consider.

Having highlights, ombre or balayage styles are particularly safe to do as the dye is only placed on strands of your hair and doesn’t touch your scalp. 

Semi-permanent pure vegetable dyes, such as henna hair dye and herbal hair dyes, are safe to use hair dyes if you want to stay completely chemical-free.

Check out the different types of hair dye you can use.

You can also take these precautions to feel safer: 

  • wearing gloves.
  • leaving the dye on for the minimum time.
  • opening the windows to avoid breathing in the chemicals
  • rinsing your scalp thoroughly when washing out the dye. 

As always, going for a free consultation at your local salon will help to put your mind at rest about what’s right for you and your hair in pregnancy.
