5 / 1000+ resultsresearch Topical Janus kinase inhibitors for the treatment of pediatric alopecia areata
This study observed that most pediatric patients with alopecia areata experienced some hair regrowth after treatment with topical JAK inhibitors, and the formulations were generally well-tolerated with mild lab abnormalities in some cases.
research Topical Janus kinase inhibitors: A review of applications in dermatology
This review discusses the efficacy and safety of topical JAK inhibitors for inflammatory skin conditions, reporting modest benefits in psoriasis and atopic dermatitis but mixed results for vitiligo and inconclusive data for alopecia areata.
research Treatment of alopecia universalis with topical Janus kinase inhibitors – a double blind, placebo, and active controlled pilot study
In this phase I study, partial hair regrowth was observed in patients with alopecia universalis using topical JAK inhibitors, though more research is needed to confirm potential as a treatment alternative to clobetasol.
research Topical JAK Inhibitors for the Treatment of Alopecia Areata and Vitiligo
Topical JAK inhibitors can effectively treat alopecia areata and vitiligo by modulating immune responses.

5 / 1000+ resultscommunity Topical finasteride (P-3074) inhibits scalp DHT up to 70%
Topical finasteride (P-3074) can inhibit scalp DHT by up to 70%, with some users experiencing systemic absorption similar to oral use. Users discuss varying application frequencies and concentrations, with some noticing side effects when overused.
community Is there any role for topical DHT antagonists, or does a 5-AR inhibitor remove the need for them as therapy
Topical androgen receptor antagonists may not be necessary if 5-AR inhibitors like finasteride or dutasteride effectively reduce DHT levels. Combining a 5-AR inhibitor with a topical androgen antagonist could potentially enhance treatment, but oral use of androgen antagonists is too risky due to severe side effects.
community Recommendation for Topical Androgen Inhibitor While on 0.5mg/Day Dutasteride
The user is taking dutasteride 0.5mg daily and seeks a topical androgen inhibitor for the scalp. They are looking for recommendations to enhance their hair loss treatment.
community Side effects of topical azelaic acid?
Azelaic acid is considered a strong DHT inhibitor with no reported sexual side effects, making it a potential alternative for those who cannot use finasteride. It can be used with minoxidil, but may cause skin irritation.
community Been using 5% topical minoxidil... Any progress??
A 28-year-old male has been using 5% minoxidil, derma stamping weekly, and daily scalp massages to address hair loss. He is hesitant to use DHT inhibitors like finasteride or dutasteride despite suggestions from others.

7 / 800 results- Got small bald patches they say are from stress? PP405 sprays could help bring them back to life. PP405 is an experimental topical gel from Pelage Pharmaceuticals that inhibits the mitochondrial pyruvate carrier; its registered Phase 2 trial (NCT06393452) tested it once daily in 78 adults with pattern hair loss, for safety and tolerability. It is not approved, not for sale, and has not been studied in alopecia areata or stress-related shedding.
- Can applying a mask with PP405 directly to thinning areas give your scalp the push it needs? No PP405 mask exists to test: PP405 is an experimental topical gel from Pelage Pharmaceuticals that inhibits the mitochondrial pyruvate carrier, it is not an anti-DHT ingredient, and it is not on sale. Its registered Phase 2 trial (NCT06393452) measured safety, not regrowth, and a rinse-out mask is in any case the wrong format for reaching the follicle.
- Did you know PP405 peptides can help protect your follicles from DHT? PP405 is not a peptide and does not block DHT: it is an experimental topical gel from Pelage Pharmaceuticals that inhibits the mitochondrial pyruvate carrier, aimed at waking dormant follicles. Its registered Phase 2 trial (NCT06393452) measured safety and tolerability in 78 adults with pattern hair loss; it is not approved and not for sale.
- How is Fluridil different from other DHT blockers like finasteride? Fluridil is a topical androgen-receptor blocker applied to the scalp, while finasteride is an oral 5-alpha-reductase inhibitor that lowers DHT throughout the body. Finasteride is FDA-approved and far better studied; Fluridil rests on one 43-man trial and is not licensed as a hair-loss medicine, so its long-term safety and effect size are unknown.
- Topical or oral? Choosing between pills and lotions according to your case. In studies, topical finasteride gave much lower blood levels of the drug than tablets but still lowered blood DHT, and whether it causes fewer side effects has not been established. There is no FDA-approved topical finasteride, and the FDA warned about compounded versions in April 2025.
