Can Taking Testosterone Cause Hair Loss?

Man with Hair Loss

Yes, taking testosterone, particularly in certain forms or at higher-than-normal levels, can potentially contribute to hair loss in some individuals. Testosterone is a hormone naturally present in both men and women, but it’s predominantly known as a male sex hormone.

In the human body, testosterone can be converted into another hormone called dihydrotestosterone (DHT) through an enzyme called 5-alpha reductase. DHT is known to be a more potent form of testosterone and can have adverse effects on hair follicles in individuals who are genetically predisposed to hair loss.

Male pattern baldness (androgenetic alopecia) is the most common type of hair loss in men. It’s characterized by a receding hairline and thinning of hair at the crown of the head. This condition is often influenced by genetic factors and hormonal changes, including increased levels of DHT.

Some forms of testosterone replacement therapy (TRT) or anabolic steroids, especially when used in excess or not under proper medical supervision, can lead to an increase in testosterone levels, subsequently increasing the conversion to DHT. Elevated levels of DHT might accelerate hair loss or exacerbate male pattern baldness in individuals who are genetically susceptible.

It’s important to note that not everyone who undergoes testosterone therapy will experience hair loss, and the impact of testosterone on hair growth can vary among individuals. Factors like genetic predisposition, dosage, duration of treatment, and individual sensitivity to hormones play a role in determining whether testosterone therapy might lead to hair loss.

If someone is undergoing testosterone therapy and notices increased hair loss or thinning, it’s advisable to consult a healthcare professional or an endocrinologist. They can assess the situation, consider alternative treatment options, and provide guidance on managing potential side effects, including hair loss, while undergoing hormone therapy.
