Impact of Diet and Dietary Supplements on Acne Vulgaris

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.

A poor diet high in sugar and insulin resistance may reduce the effectiveness of finasteride in treating hair loss. Improving diet could potentially enhance treatment results.

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.

A clean diet, including cutting sugar, gluten, and dairy, improved hair health and reduced shedding for a user on oral minoxidil and finasteride, but reverting to an old diet worsened hair condition. While diet impacts hair health, genetic factors and treatments like topical ketoconazole and hydrocortisone are also important for managing hair loss.

Reducing sugar intake may lessen scalp itchiness associated with hair loss, even when using treatments like finasteride. Some users also report similar symptoms while on dutasteride.

A 57-year-old man with male pattern hair loss and insulin resistance experienced hair regrowth and weight loss after using tirzepatide, without other hair treatments. Dysregulated glucose metabolism is linked to hair loss, with tirzepatide potentially improving hair density by normalizing insulin resistance.
