Porphyrin is a molecule, revealed by UV light, that is secreted by the microbiome and supports scalp health: As Dandruff is caused by skin cells that regenerate too fast leading to a build-up of flakes, this can be detected by K-Scan’s camera. Got dandruff? Read our article to treat your scalp and get rid of it.



K Scan’s camera is able to see your scalp in detail, which can help it understand what could be causing itching and dryness at the scalp and how to fix it.



If you feel like you’re always needing to wash your hair, then it’s likely your scalp is producing too much sebum - something K Scan’s white LED light can detect.
