Key takeaways

What matters most

  • Hair length and shape can change visible scalp coverage without showing whether the number of hairs changed.
  • Keep the original baseline and add a dated haircut note.
  • Use the first repeatable session after the cut as a new styling reference, not a replacement baseline.

Shorter hair can stand up, separate, or expose the scalp differently. Layers, fringe, fades, and a new part can also change the shape of the hairline and how light reaches the crown.

That means a photo taken before a haircut may not compare cleanly with one taken right after it. The difference belongs in the record, but it needs context.
