Does Tachyphylaxis Occur in Long-Term Management of Scalp Seborrheic Dermatitis with Pyrithione Zinc-Based Treatments?

Zinc pyrithione and ketoconazole shampoos may help reduce hair loss by removing DHT from the scalp. Users discuss various treatments, including minoxidil, finasteride, and non-pharmaceutical options like castor oil and dermarolling.

Zinc pyrithione and piroctone olamine are effective for reducing hair shedding, possibly more so than ketoconazole. There is a concern about zinc pyrithione shampoo interfering with minoxidil, but it's unclear if this is proven.

The conversation discusses the safety and use of ketoconazole shampoo for hair loss, with mentions of zinc pyrithione and selenium sulfide. Users debate the safety of these ingredients, particularly zinc pyrithione, and share opinions on regulatory differences between Europe and the US.

The user is considering switching from pyrilutamide to 0.025% topical finasteride due to concerns about effectiveness and past side effects from a scalp elixir. They aim to maintain hair until new treatments like breezula or GT00029 become available.

Betnovate and mometasone furoate were tried for scalp issues, but Zoryve and Selsun shampoo were recommended for relief. Itraconazole was suggested for stronger treatment if topicals fail.

The user is experiencing diffuse thinning and inflammation despite using 2.5mg dutasteride daily, ciclopirox, and ketoconazole shampoos. They are considering treatments like hydroxychloroquine and JAK inhibitors due to suspected scarring alopecia and have faced challenges in obtaining a scalp biopsy.
