Pregnancy is one of the most delicate phases in the life of a woman, who often has to reflect on possible negative implications considered as harmless daily habits until a few weeks before. Many expectant mothers, for example, are wondering if trichological colouring may in some way harm the health of the unborn child.
In fact, although colouration and decolouration concern the hair shaft, which is the part of the hair that emerges from the scalp, it is possible that the substances used minimally penetrate in the organism, absorbed through blood vessels arriving to the scalp.
For obvious ethical reasons, there are no specific studies on the safety of use of trichological colourations in pregnancy: the risk that some chemical elements found in dyes are damaging to the formation of the embryo takes reasonably to advise against the use of dyes in pregnancy, at least in the first quarter, which is the most important and delicate time for child development. If coexistence with some white hair or with an ugly regrowth is intolerable, it is advisable to use delicate colourations without ammonia and resorcinol, possibly water-based, to apply about half a centimetre from the skin so as to minimise contact with skin. It is also appropriate to outdistance applications as much as possible over time.
The same precautions should be maintained during breastfeeding. For more information please contact your trusted gynaecologist.
