Abstract

BACKGROUND:

Scalp psoriasis is reported to occur in 50-80% of psoriasis sufferers. Treatment of scalp psoriasis requires special consideration of product esthetics and staining potential due to the presence of hair.

AIM:

To evaluate the potential of a new, marketed liquor carbonis distillate (LCD; coal tar) solution to discolor naturally light or color-processed hair under exaggerated exposure conditions.

METHODS:

Samples of naturally light and color-processed hair from a single donor were exposed to LCD solution repeatedly over 14 days and via submergence for 24 h. Color of LCD-treated hair samples was compared with untreated control hair samples.

RESULTS:

LCD solution did not discolor naturally light or color-processed hair following repeated exposures and 24 h submergence.

CONCLUSION:

The marketed LCD solution does not appear to discolor naturally light or color-processed hair.
