Free Androgen Index: Marker of Premature Androgenetic Alopecia in Men

A 23-year-old male is considering starting Finasteride for hair loss after experiencing persistent shedding and hairline recession, with bloodwork showing normal testosterone levels but low DHEA-S and Vitamin D. He plans to discuss DHEA supplementation with his doctor and has already started Vitamin D supplementation.

The conversation is about someone planning to start finasteride or RU58841 for hair loss and wanting to know which hormones to test beforehand. They found a package for testing testosterone, free testosterone, estradiol, and DHT, and are asking if these tests are enough.

The user received hormone test results showing normal estradiol and testosterone levels, low SHBG, and normal free androgen index. They are considering starting finasteride but are concerned due to being slightly overweight.

The user experienced hair shedding after starting testosterone replacement therapy (TRT) and is considering using DHT blockers like finasteride or dutasteride to address potential DHT-related hair loss. Low ferritin levels due to frequent blood donations may also contribute to hair issues, and the user is working on stabilizing iron levels.

The conversation discusses hair loss and the impact of testosterone and DHT levels, with suggestions to monitor these levels and consider vitamin D supplementation. Treatments mentioned include finasteride and possibly minoxidil.

A user on Finasteride for 7-8 years reported unexpectedly high testosterone levels despite expecting lower levels due to age, with discussions on the impact of SHBG and suggestions to use boron to lower SHBG. Another user noted that Dutasteride significantly increased their testosterone and free testosterone levels.
