The 'permanent' part is a bit misleading - it's more like permanent reduction. You'll definitely see a huge decrease in hair growth, maybe 80-90% less, but some fine hairs might still appear occasionally. For me, the ingrown hair problem completely disappeared though, which was my main concern. The investment is significant upfront but when you calculate what you spend on razors, waxing appointments, and skincare products for razor burn over the years, it actually makes financial sense.
