Still too dark still 4wks, feel like strokes have been over done and can't see some of them. Is this an easy fix?

It's been 4wks now and still feel my eyebrows are a bit too dark and the microbladed strokes are cluttered together in places so the hair like strokes are kinda ruined by being to close. What would be the procedure to fix this?. Is it easily fixed in the touch up? Also can a lighter shade be mixed through the dark strokes that already there?
