Doing a color is not advised during pregnancy. And if the hair of expectant mothers is often beautiful, the white hair is still there. How to hide them safe for baby’s health? Update with Dr Dominique Eraud.
Coloring and pregnancy don’t mix well. If lead acetate, silver nitrate or metallic cyanides are fortunately no longer used for color hair, they are sometimes replaced by other substances (not recommended) in classic colors. Among them are ammonia which is still used to bleach the hair, because it serves as a catalyst: the ammonia swells the hair fiber and opens the scales that cover the hair, so that the coloring products can penetrate it. Other dangerous substance, paraphenylenediamine, or PPD which allows the coloring agent to penetrate inside the hair fiber and keep the color longer. If it is prohibited in all cosmetic products, it is still tolerated in hair dyes as a developer up to 6%. and manufacturers “only” have an obligation to inform consumers about its risks. Finally, resorcinol, p-Aminophenol, Toluene 2.5, Diamine Sulfate and 1-naphthol are also on the dock.
“Chemical coloring contain a significant number of dangerous substances. Some of them are potentials endocrine disruptors. It’s like applying a pesticide directly to the skull! “says Dr. Dominique Eraud, general practitioner and president of the CNMSE (National Medical Health Environment Coordination).”These substances cause in particular allergies and rashes that persist, but also respiratory problems in hairdressing professionals “, adds the doctor. These substances are even more dangerous during pregnancy because they can cross the placenta barrier through the bloodstream. Some of them are likely to cause hormonal or neurological disorders, malformations, or stunted growth in utero. “Classic colors are not recommended during pregnancy because, more than the dose, it is the moment of exposure to these toxic substances that matters. The deleterious effects of these substances are therefore increased during pregnancy and pregnant women are more likely than others to develop pathologies“, confirms Dr. Dominique Eraud.
The doctor advises future mothers not to trust the colorings without ammonia, because you should know that all conventional colors must contain a catalyzing chemical to open the scales of the hair. Another chemical is used in the absence of ammonia.
Pregnant, can we then use vegetable coloring? Thanks to the plant pigments from freeze-dried plants, it is possible to obtain a beautiful palette of colors thanks to the vegetable colors, like the Biocoiff ‘brand for example. Among their components, we find Egyptian henna, indigo, logwood, rhubarb, neutral henna, nut husk, turmeric, chestnut or even sage or indigo. “Unlike traditional coloring, plant colors do not penetrate the hair and do not pass into the bloodstream. They arise on the scalp and include the hair. They are therefore all indicated during pregnancy! They certainly do not have the same covering power as chemical colors, but allow a transparency effect to be obtained.“, explains Anne Laure Caoudal, colorist at Hair and Nature, one of the pioneering Parisian salons in the field of vegetable coloring. “We cannot obtain all the shades with vegetable colorings because it is obligatory oxygenated water to lighten. However, they allow to darken slightly, to bring more or less intense reflections depending on the base, the shine, but also a sheathing and texturizing effect. “, adds the specialist. Vegetable coloring also requires a longer exposure time.
