The 25-year-old actress said she finds the frizzy hair in the first film (Harry Potter and the Sorcerer's Stone) really "bad", reported ET online.
"When I see the images again from the first Harry Potter I immediately think how bad my hair was," Watson said.
Its been 14 years since the movie was released and the "Regression" star is surprised the way her life and career have shaped up.
"It is always surprising for me, to see how long this period of time is, where I have come and from where I started. It is pleasant to follow that journey," she said.
