Tretinoin can cause non-telogen hair loss in some men by inducing catagen-like changes in hair follicles and through retinoid toxicity, especially when used with minoxidil. Some users report hair loss even when using retinoids on the face, while others experience benefits when combined with treatments like finasteride and minoxidil.
A user shared their hair regrowth success using microneedling with a dermaroller every 6 days and minoxidil, recommending betadine (povidone-iodine) before microneedling to sterilize the scalp and enhance results. Another user noted the potential risks of iodine toxicity.
RU58841 users report mixed results, with some experiencing no benefits and others noting regrowth but potential side effects. Many prefer finasteride and minoxidil due to better-studied safety profiles.
A 31-year-old man using finasteride for a year is considering adding oral minoxidil or switching to topical minoxidil to address diffuse thinning, while also using a scalp massager and ketoconazole shampoo. Concerns include cardiovascular side effects, pet safety with topical minoxidil, and cost of telehealth services.
The user experienced improved hair density and thickness after using finasteride and dermarolling for 2.5 years but noticed hair loss when doing anaerobic exercise. They increased their finasteride dose and continued dermarolling but are considering not starting minoxidil due to its perceived hassle and uncertain long-term benefits.
