Nutrafol is suitable for the majority of people from all walks of life. There are four natural hair growth formulas available: three for women (Nutrafol Women, Women's Balance for peri- and postmenopause, and Nutrafol Postpartum for the first year after childbirth or while breastfeeding) and one for men (Nutrafol Men). We do not, however, recommend Nutrafol to anyone under the age of 18. Also, while we have no reason to believe it is harmful, there have not been enough studies to say it is safe for women who may be pregnant, so we recommend skipping it while pregnant or trying to conceive and sticking with Nutrafol Postpartum while breastfeeding. Please consult your doctor before taking Nutrafol if you have a medical condition or are taking medications (especially anticoagulants and blood thinners).
