Hello, I read your blog everyday and wanted to thank you for the information you provide. I am a 40 year old male and been on propecia and minoxidil for over 15 years with pretty good results. I find now my crown is getting pretty thin and wondering if SMP would be an option for covering up the crown for my hair which is a light brown/sandy blond .Is there such a thing as temporary SMP that might only last a few years?
Scalp MicroPigmentation (SMP) should be considered permanent. If you want a temporary solution, I would suggest you research topical camouflage products such as DermMatch or Toppik.
