I just read about "lace frontals" which are toppers that clip in the back and attach with a lace front style wig at the hairline. It looks like a great way to go in regards to breathability and avoiding any shaving. Has anyone here ever used this system before? If so, how did it work? Also, where would I be able to go and see them in person? I have never worn any type of supplemental hair, but my crown and temples are thinning so rapidly that I will need to do something sooner than later. Thanks!
