I'm no stylist, but I always try to do something special with my 5-year-old's hair for holidays. Of course, Valentine's Day called for a heart!
1. Pull up half the hair into a ponytail with a clear (or red, pink, white) elastic.
2. Split that ponytail in two and braid two braids.
3. Make a hole in the hair above the ponytail holder and push the braids up through and bring them back down and around into a heart shape.
4. Secure the rest of the hair and the braids with elastic. Voila!
