During pregnancy, your skin and hair may have gone through many changes: your hair may have become fuller or frizzier, and your skin might have developed darker spots or a variety of lumps and bumps. After your baby is born, many of those changes will fade away, only to be replaced by new changes as your hormone levels fluctuate and finally even out. Often, you can deal with these changes by mixing up your beauty routine or selecting new products for your new skin and hair.
