Lace front wigs allow for versatility in hair styles. Unlike other wigs, they can be worn for days at a time and are safe for showering and sleeping. Creating baby hair means trimming a few of the wig hairs at the hairline in order to make the wig look more like a natural head of hair. Fortunately, you don't need the hands of a master stylist to pull this off.
Secure the wig hair in a ponytail using a ponytail holder. You want to pull it away from your face so that you can see clearly.
Use a toothbrush to brush forward a few traces of the wig hair at the hairline. If you want baby hair all across the hairline, start with a small, 1-inch section at the center of the forehead. If you only want baby hair at your temples, start there. You should be dealing with no more than about 30 single strands of hair at a time. (Estimate without counting them individually.)
Pull the section of hair forward gently and hold the cosmetic razor in the other hand. Trim the hair using a slow, back and forth motion pointing the razor away from your face. For starters, trim the hair so that it's long enough to reach the tip of your nose. For longer, wispy tendrils, leave it at this length. For shorter baby hairs, pull the section of hair forward and trim again.
Create a natural look by trimming all sections to the same length. If they're not the same length, the baby hair will appear uneven and unkempt.
