Parents of girls, take note. A small spray bottle with 2 TBSP of fabric softener, the rest water = "Doll Hairspray." Easy method for smoothing and renewing any doll's hair including Barbie! (Would've been nice to know!)
Perfect approach to a grow out for straight or wavy hair even if your hair is fine. If your texture is curly your stylist should be able to alter this slighlty for your texture. Remember that color techniques are great to also get you through this process.
