The effects of Testosterone on head hair?

[Oscar Mitchell]

Does anyone know the effects of testosterone on head hair? Is it good for growth?

Or is it meaningless? Because for one, the best hair regrowth we have seen have been men who changed their sex from M to F or basically castrated themselves. Also we know castrated men don't bald. Also steroids users of test never report increased hair growth once they jump on Test for bodybuilding purposes.

Anyone know? Or have the literature I can read

I’ve learned that testosterone doesn’t necessarily help with head hair growth, and its effects can vary from person to person. I was also dealing with hair loss and decided to consult a dermatologist. Dr Ophelia helped me understand my hair concerns and discuss suitable treatment options. Getting professional advice made a real difference in understanding how to manage my hair loss.
