All semi permanent makeup procedures require a perfecting touchup session in 6-8 weeks (sometimes more than one) to complete and perfect where needed. Touchup session is crucial since it not only to seal the look so the colour retention last longer, but you can also add more, to go a bit bolder, fuller, or darker. You can also change from Microblading to Microshading or Powder Brows at this stage for a more define look.
