    TLDR Baldness does not affect vitamin D levels in men.
    In a study involving 296 healthy middle-aged and older men, researchers examined the relationship between the degree of baldness, as classified by the Hamilton-Norwood scale, and serum 25-hydroxyvitamin D (25-OHD) levels. Despite considering factors such as age, time of year, exercise, sunscreen use, skin type, and hat-wearing habits, the study concluded that there was no significant difference in 25-OHD levels across varying degrees of baldness (P=0.60). This finding suggests that baldness does not affect vitamin D status in men and does not support the hypothesis that baldness could have an evolutionary advantage related to vitamin D synthesis.

Users humorously suggest using oils topically and discuss other hair loss treatments, but the main focus is on the science behind fatty acids and their role in 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.
