Seborrheic Dermatitis and Hair Loss
One of the more uncommon symptoms of seborrheic dermatitis is hair loss. The oil the scalp produces combined with the malassezia fungus can cause irritation and inflammation to the hair follicles, making it difficult for hair to grow [source: AHLA]. The best way to prevent hair loss is to use an over-the-counter antidandruff shampoo that contains selenium sulfide, zinc pyrithione, coal tar or ketoconazole. A dermatologist may prescribe an antifungal cream or antibiotic to combat the malassezia, and sometimes a topical medication that contains corticosteroid can help reduce inflammation.
The hair loss should subside with proper treatment, but it's important to continue treatment even after your symptoms decrease because seborrheic dermatitis is chronic and can recur [source: AHLA]. If the hair loss doesn't subside, it may be caused by something more severe than seborrheic dermatitis, and you should see a doctor [source: Evans].
