Hair Coloring In Pregnancy Is It Safe

    Hair care and hair coloring preparations include a number of diverse chemicals. Each product is different, and before using it in pregnancy you need to read the list of ingredients carefully before coming to conclusions.

    Hair Coloring During Pregnancy

    Women have been dyeing their hair for a very long time, but as we become more aware of the possible effects of everything we do in pregnancy, concerns started to be raised about something as simple as coloring your hair.

    So, is it safe to color your hair while pregnant? There is no simple answer to this question, and the truth is we can't be 100% sure it's safe. Some doctors say it's OK, while others are more cautious.

    • Hair curling products typically contain keratin-reducing compounds and a wave-forming agent (often a carboxylic acid or salt of an unsaturated hydrocarbon). An oxidizing agent is used to set the curl.
    • Hair straighteners may contain sodium or potassium hydroxide or a combination of calcium hydroxide and guanidine carbonate. Bleaching color from hair typically involves the use of hydrogen peroxide.
    • Some hair coloring products contain lead acetate, which forms black insoluble lead sulfides when the lead in this compound combines with the available sulfhydryl groups in hair. When used as directed, the lead exposure from these products has been estimated to be about 0.5% of the daily amount of lead absorbed from food and air and in one review it was concluded that this use of lead acetate does not adversely affect fetal or postnatal development.

    It is unknown what, if any, effect on pregnancy many of the chemicals have because teratogenicity (causing damage to a fetus) testing in these products has not usually been reported. In the work that has been done, some compounds, such as aminophenol, were not teratogenic when tested in rats. In contrast, some hair dye preparations have been associated with birth defects in mice. It should be remembered that testing typically involves feeding large amounts of the test substance to the animals. The extent to which these results are predictive of effects from topical exposure in the human is unknown.

    A questionnaire study of women with cosmetology licenses identified an increase in spontaneous abortion among those who worked long hours, particularly applying bleaches and permanents. Exposure to formaldehyde-based disinfectants was also associated with an increase in miscarriage suggesting an approximate doubling of risk Additional epidemiology studies have produced data both positive and negative regarding the use of hair care chemicals or work in cosmetology and adverse pregnancy outcomes.

    Here are some tips for hair coloring in pregnancy:

    1. Wait to color your hair until after the first trimester.
    2. Avoid processes that involve scalp contact.
    3. Try temporary color.
    4. Opt for highlights.
    5. Even vegetable dye is not necessarily safe.
    6. Don’t expect too much of your hair color in pregnancy.
