Acitretin, an oral retinoid, can cause hair loss. This case study documents a rare instance of hair color darkening after acitretin treatment, suggesting potential repigmentation effects.
Area of Science:
- Dermatology
- Pharmacology
Background:
- Acitretin is a systemic retinoid used for various skin conditions.
- Alopecia (hair loss) is a known potential adverse effect of acitretin therapy.
Observation:
- This report details a patient experiencing hair color changes during acitretin treatment.
- The patient's hair color notably darkened following a course of acitretin.
Findings:
- Hair color repigmentation after acitretin use is not commonly reported.
- This case presents evidence of acitretin potentially influencing hair pigmentation.
Implications:
- Further research is warranted to understand the mechanisms behind acitretin-induced hair color changes.
- This finding may inform dermatologists about unexpected dermatological effects of retinoids.

In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...
