Phosphodiesterase (PDE) Inhibitors for the Treatment of Inflammatory Skin Conditions

The conversation discusses using PGE2 as a hair growth stimulant, comparing it to minoxidil, and considering the addition of Setipiprant. Concerns about side effects like skin damage and cost are also mentioned.

Topical pirfenidone is highlighted as an effective anti-inflammatory and anti-fibrotic treatment for hair loss, particularly in addressing perifollicular fibrosis, which may enhance the effectiveness of standard treatments like finasteride and minoxidil. The user also uses calcipotriol, MCT oil, ciclopirox shampoo, and benzoyl peroxide shampoo as part of their regimen.

Setipiprant and Fevipiprant are questioned for their effectiveness in hair maintenance, with skepticism due to lack of convincing results beyond vellus hair growth. The user is satisfied with Minoxidil and Finasteride but is curious about the potential of DP2 inhibitors.

The user added P5P (vitamin B6) to their shampoo to reduce scalp itch, which improved significantly. They have been using finasteride for hair loss but are exploring additional treatments like topical antiandrogens and prolactin inhibitors.

PP405 shows initial promise for treating androgenetic alopecia, with safety confirmed in early trials, but skepticism remains due to limited data. Further trials are needed to determine its true efficacy and potential market impact.

New hair loss treatments PP405 and VDPHL01 are discussed with skepticism and hope, alongside existing treatments like minoxidil and finasteride. Users express frustration over limited progress since the 1980s but remain cautiously optimistic.
