The most important hormones affecting the health of skin, hair and nails are estrogen (especially in proportion to testosterone), thyroid hormones and cortisol. Estrogen: Not surprisingly, estrogen levels affect every part of the body, including hair, skin and nails.
The short answer is that there is no scientific evidence to suggest that taking prenatal vitamins can help hair or nails grow longer, faster or stronger. It is true that many pregnant women find that their hair becomes thicker or shinier and their nails stronger during their pregnancies. Some women attribute these changes to their prenatal vitamins, but the reality is that elevated estrogen levels and other changing hormones during pregnancy are likely responsible.
