Finasteride is effective for DHT/AR-driven hair loss but not for chromosome 20-driven cases, where treatments like minoxidil, prostaglandin analogs, and low-level laser therapy may be more beneficial. Genetic testing can help determine the underlying cause of hair loss to tailor treatment effectively.
Some hair loss may be linked to chromosome 20, which isn't affected by DHT blockers like finasteride. Treatments like minoxidil, microneedling, and genetic testing are suggested, but their effectiveness for this type of hair loss is uncertain.
The conversation discusses how Caucasian men are more likely to experience hair loss due to genetic predisposition, with factors like the androgen receptor on the X chromosome playing a significant role. The user also expresses confusion about the evolutionary reasons for hair loss, especially in colder climates where it would seem beneficial to retain hair for warmth.
Finasteride can effectively slow or halt hair loss, even for those genetically predisposed to significant balding, like Norwood 6 or 7. Many users report long-term maintenance or improvement, often combining it with other treatments like Dutasteride or Minoxidil for better results.
The conversation discusses various theories of hair loss, including DHT sensitivity and genetic factors, with the user willing to use themselves for research due to having a hair loss gene but different hair loss patterns compared to their brothers. Specific treatments were not mentioned in the provided text.
