A user who shared progress pictures of their scalp using a microscope camera, demonstrating the difference between healthy and miniaturized hair. Various explanations for the cause of this were discussed, such as DHT build-up in scalp sebum causing an autoimmune response leading to inflammation and eventual hair loss, with some suggesting a do-it-yourself treatment involving adding ascorbic acid powder to shampoo.
Gut microbiota significantly influences androgen metabolism, impacting hair loss treatments like finasteride. Probiotics, dietary changes, and fecal microbiota transplants may help manage DHT levels and improve hair health.
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.
Hair loss theory suggests imbalance between Vitamin D Receptor (VDR) and Androgen Receptor (AR) activation. Proposed treatment includes upregulating VDR, downregulating AR, and improving mitochondrial health.
Scalp tension from the occipitalis muscle is theorized to contribute to hair loss, but most believe DHT and genetics are the main causes. Treatments like finasteride and minoxidil are considered more effective than addressing scalp tension.
