Single Hair Analysis by X-Ray Fluorescence Spectrometry Detects Small Changes in Dietary Zinc Intake: A Nested Randomized Controlled Trial

Zinc supplementation caused significant hair shedding for the user, who had been successfully managing hair loss with finasteride, minoxidil, RU58841, and microneedling. The user discontinued zinc after noticing no libido increase and believes the hair loss was due to zinc's interaction with other minerals or hormonal changes.

The conversation discusses hair loss and bloodwork results, focusing on zinc, vitamin D, and ferritin levels. The user is experiencing telogen effluvium after surgery and seeks advice on supplementation.

The user is experimenting with a zinc sulfate and B6 topical solution called "Zix" for hair loss, alongside using a zinc oxide scalp mask and low-level laser therapy (LLLT). They report minimal hair loss after three months of use and are seeking feedback from others who have tried similar treatments.

Zinc is not effective for hair loss unless there's a deficiency. Finasteride and minoxidil are recommended treatments.

Zinc supplements may slightly increase DHT by affecting testosterone conversion, but are generally beneficial for health. A 15mg Zinc to 1mg Copper ratio is recommended.

Low ferritin levels may contribute to hair loss, and raising ferritin above 40 or 70 ng/mL might help with hair regrowth. Some users also consider zinc deficiency and absorption issues as potential factors.
