TLDR Thyroid hormone receptor β1 is found in human hair follicles and helps them survive.
Researchers investigated the expression of thyroid hormone receptors (TRs) in human hair follicles and found that TRβ1 was the predominant form. Immunoreactive TRs were present in both dermal and epithelial compartments of the pilosebaceous unit. Additionally, they studied the effects of 3,3', 5-triiodo-L-thyronine (T3) on hair follicle survival in vitro and discovered that physiological levels of free T3 significantly enhanced hair follicle survival.
The conversation discusses using T3 (triiodothyronine) as a topical treatment for hair growth, with some users noting it showed promising results in studies but lacked follow-up. Users express interest in trying T3 due to its potential effectiveness compared to Minoxidil.
Experimenting with trestolone as a treatment for hair loss in an attempt to avoid DHT-related treatments such as finasteride and dutasteride, and discussing the potential effects of its receptor selectivity on the androgen receptors in the scalp.
A new topical treatment, TH07, combining finasteride, latanoprost, and minoxidil, is entering phase III trials with promising early results. Some users express skepticism, noting the treatment uses existing products.
A 19-year-old transgender individual is experiencing worsening temple recession despite taking female hormones and 1.25mg finasteride. They are seeking advice on additional treatments to address hair loss.
A 30-year-old man experienced significant hair loss after starting testosterone replacement therapy (TRT), which did not improve with daily finasteride and minoxidil. He is considering restarting TRT and is seeking advice on using pyrilutamide or RU58841 to prevent further hair loss.
User discusses Alfatradiol (17a-Estradiol) as a potential hair loss treatment with mixed results. Concerns include low dosage, receptor theory, and possible increased aromatase activity on scalp.
