I am curious to know if it does. I wax my pubic hairs so it will be an easy way to know my actual growth rate and figure out how much I am retaining. My last wax appointment was June 9 (don't judge!) and I measured my pubic hairs look last night and it was 1.15 inches. If this is the same growth rate for my hair, it would be consistent with the average and also mean I am retaining about 75-80%. I am okay with retention rate, I just want to know for sure.
