HairStroke is an eyebrow threading technique that requires a powerful modern tattooing device with high capacity and precision, and a stable machine operation. Conventional tattooing machines that lack precision, vibrate or do not have a needle tip that automatically adjusts depth will not be able to perform this “special” technique. This technique also requires the Master to have high expertise and need to be careful and meticulous to be able to create a quality Hairstroke thread product.
