How to measure head size

To determine the right size wig for you, measure the circumference of your head from the front hairline, behind your ear, to the nape of your neck, to your other ear and then back to the front hairline. Jot down your measurement then consult the table below. Please note that sizes may vary slightly by brand.

Many wigs come in petite, average and large cap sizes. Average size wigs, however, tend to fit about 90-95% of customers. See wig size chart below, so you are able to determine the best cap size for you!

Protection Perfection

This is a very good thermal product. I rarely use heat but when I do I use this . I sometimes work out a wave or a curl that’s in the wrong place for me … I wouldn’t think of putting heat to my wigs without this heat treat .

Really good stuff

I made the mistake of using a curling iron set on very low on an non-heat friendly wig! I sprayed this protectant on first and I am sure it saved my wig. I only discovered afterwards that I was working on regular synthetic. I don't recommend doing this ever but this was a mistake that could have turned out really bad. This is a great product that saved the day!

A must have

I use this really keeps the fibers looking good. I didnt use it in the beginning of my wig wearing journey, because I was still learning, and the difference in the wigs that never had this on it compared to the ones that do is incredible

My beautician used it on my new topper and she had no complaints.
