"I have been using Minoxidil 2% (Regaine) for two years and I am two months pregnant. My gynaecologist asked me to stop applying Minoxidil, but if I do so, I fear my hair will start falling again."
There are no documented studies about women and the influence of Minoxidil on their foetus during pregnancy (by animals, there is no teratogen effect). However, as a small part of Minoxidil goes through the skin when it is applied on it, it is recommended to stop using Minoxidil during pregnancy. Moreover, hormonal changes caused by the pregnancy will help reduce hair loss and will balance possible losses when stopping the treatment.
