Should I do SMP or a hair transplant?

First you must ask yourself if it is hair that you want. If the answer is yes, then you must get an objective assessment with good numbers on (1) your donor density and (2) your hair mass index. These two factors will determine if you have enough hair to cover your entire head. Keeping in mind that if it is remotely reasonable, then you might be able to combine Scalp Micropigmentation (SMP) with a hair transplant to get a full head of real hair (see here: https://newhair.com/wp-content/uploads/2018/11/Combining_Follicular_Unit_Extraction_and_Scalp.98621.pdf ). But if you decide to have SMP, you could do it first ( https://scalpmicropigmentation.com/), see how you like it. If that turns out that you rather have a hair transplant and if the analysis of your donor area points to a good possibility of having a hair transplant as I discussed above, you can then go the transplanted route. Having SMP does not preclude a hair transplant.
