If untreated asbestos-infested scalps remain untreated for a longer period of time, irreversible hair loss can occur. The hair falls out in clumps or can be easily and painlessly pulled out of the scalp.
External therapyThis section has been translated automatically.
- Scaling therapy with salicylic acid-containing external agents such as 10% salicylic acid oil/ointment (Rp221) or salicylic acid oil 2/5 or 10% with triamcinolone acetonide 0.1%. The oil containing salicylic acid should be spread generously on the scalp. Then cover the entire capillitium for several hours with a foil, as final as possible, and fix it with a tubular bandage (a towelling cap or a cotton cap, also a surgical cap is sufficient). Repeat the identical procedure the following day; after 2-3 days (also possible daily) wash out the hair thoroughly. Rising scales can be combed out with a large comb without a firm pull.
- Alternative: After this keratolytic primary treatment, an occlusive treatment with topical glucocorticoids in O/W bases, such as triamcinolone cream(e.g. Triamgalen, Rp259 ) or a glucocorticoid-containing gel such as 0.05% betamethasone gel (e.g. Diprosis gel) has proven to be effective. Afterwards, again remove scaly plaques mechanically.
- Alternatively: local application with a tar-containing external agent (5%-10% Liquor carnbonis detergens in Lygal ointment).
- Subsequently, the formation of psoriatic plaques should be reduced by keratolytic maintenance therapy (once/week, possibly every 2 weeks). Additionally, special anti-dandruff shampoos (e.g. de-Squam®, Almirall). An alternative would be a shampoo containing tar (e.g. Tarmed® shampoo with 4% tar added; available again on prescription since June 2015).
- Remark: It is important to draw the patients' attention to the fact that pityriasis amiantacea is often accompanied by hair loss, which can become more noticeable in a phase of intensified local therapy.
