We get this question a lot. Only your obstetrician can you tell you what's safe for you, but, we can tell you that the reason that most serums aren't safe for pregnant women is because they contain hormones. And the more common hair serums contain minoxidil, which is a drug. VEGAMOUR hair serums do not contain synthetic hormones, nor do they contain drugs.
They're always vegan and natural. But just to be sure, we'd recommend that you take a list of the ingredients (found on any product page) to your doctor.
