Testosterone within the normal range does not significantly contribute to male pattern baldness (MPB); DHT is the main factor that can be controlled. Genetics play a crucial role in hair loss, and treatments like finasteride and dutasteride, which block DHT, can help despite potentially raising testosterone levels.
Prolactin and cortisol are identified as key factors in hair loss, with stress hormones impacting hair shedding. Finasteride and minoxidil are effective treatments, while DHT's role and individual sensitivity are significant factors.
Finasteride can cause gynecomastia, which may be reversible by stopping the drug and using selective estrogen receptor modulators (SERMs) like tamoxifen. Lifestyle changes such as weight loss and avoiding alcohol can also help, but surgery may be needed if the condition persists.
The conversation discusses whether 2.5mg of dutasteride or 200mg of testosterone weekly is more influential in preventing hair loss, with various personal experiences indicating that the effectiveness is dependent on the individual's genetic profile. Some users report that dutasteride is likely to be more effective at the given doses.
