Women in their 20s are often more experimental, establishing their recent adulthood, Ken says. Have fun with your style!

Hair don’ts are definitely more forgiving at this age.

Ken says he doesn't usually recommend going to extremes, but if you are adventurous, now is the time. Establish what your likes and dislikes are. If you are a long-hair girl this would be a great time to go short.

Long, short, light or dark—wear it with confidence!
