Peptides like TB500, KPV, GHK-CU, and BPC-157 are overhyped for hair growth with limited proven effectiveness in humans. Combining peptides with delivery methods like iontophoresis and sonophoresis shows promise, but many claims remain unproven.
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.
Oral minoxidil may cause dry skin and dark eye bags but doesn't significantly age the skin. Topical minoxidil is toxic to cats, and some users prefer finasteride.
A 22-year-old male is not seeing hair regrowth after using minoxidil and finasteride for a year and additional treatments for three months. Suggestions include improving scalp absorption with sea salt and trying a lipid-based solution, microneedling, and possibly switching to dutasteride if no improvement after 1-2 years.
Dutasteride can lead to increased cholesterol and liver fat. The user is reconsidering its use due to high cholesterol and lipid levels despite a healthy lifestyle.
