Hair dye and its use during pregnancy is a common concern.
But if you regularly dye your hair, chances are you're not going to want to stop for nine months during your pregnancy. There is limited research into using hair dye in pregnancy, so if you are concerned, ask your GP or midwife for guidance.
Although experts say modern hair dyes are much safer than their predecessors, with chemicals having very low toxicity, there are natural, chemical-free alternatives available.
Daniel Field, the UK's leading organic and mineral hair care brand, is a good place to start. Expertly researched and salon-tested, Daniel Field products are formulated with fine ingredients, including high performance certified organic essential oils and non-genetically modified cereal oils and proteins.
The Natural Colours range is free from ammonia, hydrogen peroxide and preservatives, available in 19 shades and even claims to cover up greys.
For sun-kissed radiance, check out the new Daniel Field Natural Lights seaweed highlighting kit, which is formulated using natural seaweed extract, certified organic avocado essential oil for phyto-lightening, and is also odourless.
Each pack comes with an essential oil conditioning treatment, containing a range of delectable ingredients including certified organic French lavender, aloe vera and honey to boost shine and radiance, as well as give hair luminous highlights.
Daniel Field Natural Colours and Natural Lights cost £7.99 each and are available from Sainsbury's, or you can order them online at Danielfield.com.
Highlighting your hair - which only puts dye onto strands of your hair - reduces any risks there may be because the chemicals used are not absorbed into your scalp and bloodstream.
Semi-permanent vegetable dyes, including henna, are also worth a look if you are worried.
