Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
The user "ajsr8" shared their story of hair loss despite being on treatments. They started using finasteride in 2019 and later tried topical minoxidil, but it didn't seem to work. They also experienced side effects from other treatments. They are considering cutting off their hair and stopping the medications if there is no improvement in three months. Other users suggested trying different treatments and getting a blood test to check for underlying conditions.
Dutasteride takes 1-3 months to affect scalp DHT levels, not just a week. The prostate absorbs Dutasteride faster than the scalp due to different vascular networks and enzyme densities.
Brian Dye's theory links skeletal malocclusion type II to hair loss, suggesting it's a blood flow issue. Treatments mentioned include minoxidil, finasteride, and anti-inflammatory drugs like benaxoprofen.
Lichen Planopilaris (LPP) is an autoimmune condition causing permanent hair loss and fibrosis, often misdiagnosed. Treatments include pioglitazone, topical corticosteroids, anti-inflammatory medication, and Jak inhibitors.
