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.
The user is using 2.5mg oral minoxidil and Nizoral shampoo for hair regrowth, noticing some improvement. They are considering increasing the dosage and exploring alternatives to topical minoxidil/finasteride due to concerns about toxicity to cats.
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.
A 37-year-old male resolved scalp folliculitis by adopting a low-histamine diet and taking Vitamin A, Zinc, and Fish Oil, leading to better skin health and thicker hair. He warns about the potential toxicity of excessive Vitamin A intake.
A user shared a tragic experience where their cat died after being exposed to Minoxidil, warning others of its toxicity to pets. Some users discussed switching to oral hair loss treatments, while others expressed condolences and shared their own concerns and experiences with topical treatments around pets.
