The Application of an Oral Zinc Tolerance Test to Assess Zinc Absorption From Three Different Dietary Sources in the Dog

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.

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.

Taking zinc and copper may offset copper depletion and potentially aid hair health when used with finasteride. The user is considering whether to use these supplements alongside finasteride or wait until switching to dutasteride.

The conversation discusses using finasteride for hair loss and whether taking zinc or ZMA can prevent side effects. Users share experiences, noting zinc may increase libido but could also lead to hair shedding, while finasteride might initially increase testosterone but lower it over time.

A 36-year-old man with androgenetic alopecia suspects copper and zinc deficiencies may be accelerating hair loss and is supplementing copper to address this. He is also monitoring blood sugar levels due to previous prediabetes concerns and plans to test for insulin resistance.

The conversation discusses using zinc sulphate and azelaic acid to inhibit 5 alpha-reductase activity, which could potentially treat androgen-related skin conditions like hair loss. Combining these with vitamin B6 could enhance the effect, potentially offering an alternative to finasteride.
