Linking Diet to Acne Metabolomics, Inflammation, and Comedogenesis: An Update

Eating high sugar or fast foods can cause an itchy, inflamed scalp, especially in areas with hair thinning. Reducing sugar intake and consuming vitamin D3 and fatty fish may help alleviate symptoms.

Controlling insulin levels through intermittent fasting and a low glycemic diet may improve hair quality by reducing androgens. It's important to maintain proper nutrition, including electrolytes and protein, during fasting.

High sugar diets may worsen hair loss by increasing 5α-reductase activity and androgen levels, especially in women with PCOS. A low sugar diet might reduce scalp DHT levels, similar to finasteride, but genetics also significantly influence hair loss.

Excessive sugar and high-fat diets are linked to male pattern hair loss, with sweet beverages being a significant factor. Moderation in diet is advised, as diet alone may not fully prevent hair loss due to other factors like DHT sensitivity.

Excess sebum rich in cholesterol and triglycerides can lead to hair loss through inflammation, with treatments like Ciclopirox shampoo, Benzoyl Peroxide shampoo, and Clindamycin gel recommended for managing conditions like seborrheic dermatitis and folliculitis. Pioglitazone is suggested for Lichen Planopilaris, while Omega-3s and reducing processed foods may improve sebum quality, though genetic factors play a significant role.

Dairy may contain DHT precursors that could affect hair loss and prostate health, with some users noting reduced hair shedding after eliminating dairy. Individual responses to dairy and DHT blockers vary, with some attributing hair health to diet changes and others seeing no impact.
