Vitamin B12 Deficiency: A Rare Cause of Excessive Daytime Sleepiness

Hair loss due to vitamin B12 deficiency is discussed, with some users suggesting supplements and dietary changes, while others recommend medications like finasteride or dutasteride. The conversation highlights differing opinions on the cause of hair loss, with some attributing it to genetics or male pattern baldness.

A user is experiencing hair regrowth after treating vitamin D, B12, and B9 deficiencies, noticing some improvement after 9 months. They are unsure if further improvement will occur or if they have reached the end of progress, with a possibility of androgenetic alopecia (AGA) being suggested.

Dutasteride and Minoxidil are not effectively preventing hair loss. Supplementing with Vitamin D and B12 is recommended.

Vitamin deficiencies, particularly in vitamins A, B, C, D, and minerals like iron, zinc, and copper, can lead to hair loss. Dietary changes, such as eating more nutrient-rich foods, can improve hair health.

Betacarotene's effect on hair loss is discussed, with concerns about excessive vitamin A. The user also questions if 15mg melatonin impacts vitamin A levels.

The user is experiencing sleep issues after starting finasteride for hair loss and is considering using magnesium or melatonin to improve sleep. Other users suggest that sleep disturbances are a common side effect initially, but may improve over time.
