Yes. There is no need to replace or discard a Barbie doll just because her hair is a little lackluster. Start by combing it. Then add some conditioner. After a couple of minutes, rinse the conditioner off with lukewarm running water. Next, apply a mild shampoo to your hair and rinse. Condition once more before rinsing and gently remove excess water with a towel. Lastly, spritz on a leave-in conditioner, comb through, and let hair air dry. Your Barbie's hair is like new!
