80 % of Patients May have some Response to Hydroxychloroquine for LPP — Donovan Hair Clinic

Perifollicular scale was among the most important trichoscopic features to improve. At baseline, 60% of the patients (N=9) presented severe perifollicular scale, while at the end of the study, only 13% (N=2).


This is a valuable study. It’s challenging to know how to define treatment success in scarring alopecia. Treatment success becomes clearer and clearer after 2,3 and 4 years and sometimes is a bit more difficult in the short term. A patient may have redness but no hair loss as therefore is said to have a partial response. Overall, about 80% of patients have some kind of benefit with hydroxychlroquine and clobetasol. For 20 % of patients, this may be enough and no further treatment is needed. For another proportion of patients, some additional treatments may be needed in order to fully halt the disease.

These data overall are similar to other studies of hydroxychloroquine in treating LPP.

a) Chiang et al 2010.

In 2010 Chiang et al conducted retrospective chart review of 40 adult patients with LPP, and/or FFA who were treated with hydroxychloroquine for up to 12 months from 2004 to 2007. The authors found that there was significant reduction in the LPPAI at both 6 and 12 months. After 6 months, 69% had reduced symptoms and signs ( a reduction in the LPPAI). At 12 months, 83% had improvement (reduction) in symptoms and signs.

b) Dhonncha EN et al. 2017

In 2017, Dhonncha et al evaluated the benefits of hydroxychloroquine in 23 patients with LPP. 61 % had a complete response and 9 % had a partial response.
