Scalp micropigmentation is suitable for bald people with sparse areas or receding hairlines. It creates the look of a full-shaved head through a non-surgical procedure of using a fine needle to deposit cosmetic-grade pigment on the scalp. Completely safe and done by a trained specialist.
You can see from the photos that the sparse areas were covered in-between sessions. The last photo looks as if the clients just had a natural full-shave.
