Hair Cycle in Dogs with Different Hair Types in a Tropical Region of Brazil

Hair follicles are mostly dormant but can be reactivated with treatments like minoxidil, finasteride, and microneedling. A new drug, PP405, shows promise for hair regrowth but may not be available until 2027-2028.

The user experienced significant hair loss after extended fasting, initially thought to be Telogen Effluvium, but later suspected male pattern baldness. They tried finasteride briefly but stopped due to concerns about side effects, and are unsure if the hair loss is due to Telogen Effluvium or another cause.

Hair loss may be influenced by mechanical tension and inflammation, with the hi-c5 protein amplifying androgen effects, leading to follicle miniaturization. Treatments like finasteride, minoxidil, and scalp massages are suggested to manage hair loss.

Scalp hydration may influence hair growth by affecting the signaling pathways that control the hair growth cycle. Users suggest using facial moisturizer, aloe vera, and oils for scalp hydration.

Hair follicles can be dormant and potentially revived with treatments like finasteride and minoxidil, but irreversible loss occurs if certain structures are destroyed. Early intervention is more effective, and additional methods like microneedling may help.

A 16-year-old experiencing hair thinning noticed a shift from shedding long hairs to shorter hairs, while using Vitamin D, biotin supplements, ketoconazole shampoo, and improving diet. They are questioning if the short hairs indicate regrowth or androgenetic alopecia (AGA).
