The answer is not so simple. We realize you may want to have the SMP procedure so you can wear your hair short without worrying about your hair transplant scar showing through. SMP can disguise your linear hair transplant scar or patchy FUE scars, but there is an important limitation. You cannot keep your hair too short or the shape of the scar will show through like a line or a step in the contour of your hair. In addition, in certain lighting conditions and angles, the scar will be apparent to the discerning eye.
Keep in mind that you are seeing the SMP pigment under a layer of translucent skin, so you cannot expect it to replace the feeling of a hair shaft as it grows. In other words, SMP is not a substitute for real hair. When your scalp is shaved or your hair is very short (1mm), SMP will blend in and disguise the scar. However, as your hair grows out past 1mm, the texture of your hair will not match with the flat SMP layer. You will notice a gap.
