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.
Prolonged use of topical minoxidil and finasteride can lead to neuroendocrine and autonomic dysfunction, causing severe sensitivity and side effects. Recovery involves avoiding these treatments, supporting neurosteroid recovery, calming the sympathetic system, and rebuilding scalp health naturally.
Hair loss is linked to cellular physiology and the IGF-1 to TGF-B1 ratio, not just androgen sensitivity. The theory lacks evidence, while finasteride and minoxidil are effective treatments.
N-Acetyl-Cysteine (NAC) was found to improve hair parameters in men with early-onset androgenetic alopecia, showing increased terminal hair count and decreased vellus hair count, with good tolerability. NAC, used alone or with minoxidil, may help due to its antioxidant properties, though its effectiveness can vary among individuals.
Finasteride can reduce neuroactive steroids, causing side effects like depression, anxiety, and sexual dysfunction. Some users experience persistent symptoms after stopping finasteride, while others use alternative treatments like topical solutions.
