Hair and nails grow faster during prègnancy
A surprising side effect of prègnancy is that nails and hair grow faster than usual. This is due to changes in hormones as well as increased blood circulation and metabolism supplying nutrients. According to Amy O'Connor, writing for What to Expect, a prègnant person's hair also "might feel thicker and look more shiny and healthy than usual." Though she warns that it can occasionally mean that the expecting "may suddenly sprout strands in places [they'd] rather not."
