Well since no one has responded yet, I wanted to say welcome and you are in good hands at Toplace. One of the best women to speak with on here would be Debbie and I am sure that she will post a response when she sees your request for info. I do not have "very" long hair, but it is longer than most of the guys who post on this site. I start with 7"hair and it is slightly shorter when cut. I do everyday activities including sleep with the hair attached for about three weeks at a time. I clip the hair up when attaching, ( there's a manly picture)but I use tape st-30 for the perimeter and glue for the front. Actually the hair is easier to get out of the way when it is longer. I probably haven't answered much, but you will save money and your cleanup will take less time than the drive to and from your HCM appt. The look and quality will please you as well.
