Scalp Micropigmentation (SMP) is an innovative, non-surgical hair loss solution, performed at our Harley Street clinic in London.SMP treatment improves the visual density for those with little to no hair, and can also create a thickening effect for longer hair by directly darkening the scalp and reducing the contrast ratio between your hair and scalp tone. At our SMP clinic in London, we use Alivio gamma-sterilised pigmentation ink, combined with a 3 micron precision needle to accurately simulate short, shaved follicles throughout your scalp.
