A viewer asked Dr. John Watts, a dermatologist, trichologist and hair transplant surgeon in Hyderabad who has performed over 2,000 hair transplant surgeries, whether low testosterone levels can trigger hair fall. It's one of the most persistent myths around hair loss, alongside claims linking it to habits like masturbation.
Testosterone Alone Isn't the Cause
Dr. Watts is direct about it: both low and high testosterone levels, on their own, do not directly cause hair loss. Testosterone can convert into DHT (dihydrotestosterone), the hormone linked to pattern baldness, but this typically doesn't lead to hair loss unless there's a strong genetic predisposition running in the family.
This distinction matters because many people searching for reasons behind their hair fall focus on hormone levels rather than looking at their family history. Dr. Watts's point is that testosterone is just the raw material -- it's the genetic sensitivity to DHT within a family line that ultimately determines whether hair loss progresses.
Genetics Is the Real Driver
For people with a family history of baldness, the risk of significant hair loss is much higher if proactive steps aren't taken early. "Hair loss can be triggered by various factors such as stress, nutritional deficiencies, and genetic predisposition. Seeking timely advice from a dermatologist, making dietary changes, and using appropriate medications can often address the issue effectively," Dr. Watts says.
Why Early Diagnosis Matters
Dr. Watts stresses the importance of catching hair loss early. If diagnosis and medical treatment are delayed, a hair transplant procedure may become the only viable option left. Acting on early signs -- rather than worrying about testosterone levels -- gives patients the best chance of managing hair loss effectively.
The takeaway, in Dr. Watts's words, is that testosterone is a myth worth retiring -- genetics, stress, and nutrition deserve far more attention.
