Testosterone Replacement Therapy (TRT) and Male Pattern Baldness: Unraveling the Connection

Updated: Jan 7



Testosterone Replacement Therapy (TRT) brings a host of benefits for men seeking hormonal balance and optimization, but the correlation with male pattern baldness has raised concerns. This article explores the physiological impact of dihydrotestosterone (DHT) on hair follicles and the possibilities for reversal.


Male pattern baldness is a complex interplay of genetics and hormones, particularly the androgen dihydrotestosterone (DHT). DHT is derived from testosterone through the action of the enzyme 5-alpha-reductase.

In individuals genetically predisposed to hair loss, DHT binds to androgen receptors in hair follicles, initiating a process of miniaturization. This leads to the gradual shrinking of follicles, resulting in thinner and shorter hair strands and, eventually, hair loss.


Again, most men on TRT do not experience hair thinning or hair loss. The men that do often have a genetic component increasing their chances.


It's about DHT:

DHT's influence on hair follicles lies in its ability to shorten the hair growth cycle. When bound to androgen receptors on the hair follicle cells, DHT disrupts the normal growth pattern, causing the follicles to spend more time in the resting phase (telogen) and less time in the active growth phase (anagen). Over time, this disruption results in the characteristic pattern of male pattern baldness, starting with a receding hairline and thinning at the crown.


Reversibility of DHT-Induced Hair Loss:

Once hair follicles have undergone significant shrinkage, it becomes challenging for them to return to their original size and produce thick, healthy hair. Therefore, prevention and early intervention are crucial when addressing DHT-related hair loss.


Treatment Strategies:

  1. Medications: Finasteride and dutasteride are medications that inhibit 5-alpha-reductase, reducing the conversion of testosterone to DHT. These drugs have shown efficacy in slowing or halting the progression of male pattern baldness. However, their use should be under the guidance of a healthcare professional due to potential side effects.

  2. Topical Minoxidil: Minoxidil, a topical solution, is known to stimulate blood flow to the scalp and promote hair regrowth. While it doesn't directly address DHT levels, it can complement other strategies for maintaining and improving hair density.

  3. Lifestyle Modifications: Regular exercise, a balanced diet rich in essential nutrients, and stress management can contribute to overall hair health. While these lifestyle changes may not reverse hair loss caused by DHT, they can create a conducive environment for maintaining healthier hair.

  4. At Vitalit-T Men's Health Clinic, we prescribe a combination formulation including MINOXIDIL/MELATONIN/GHK-Cu/TRETINOIN/CAFFEINE SCALP FOAM (5%/0.1%/0.5%/0.025%/2%). This is used twice a day.


Understanding the role of DHT in male pattern baldness sheds light on the challenges associated with reversing the process. While complete reversal may be challenging, early intervention and a holistic approach, combining medical interventions, lifestyle adjustments, and ongoing monitoring, can help mitigate the impact of DHT on hair follicles.
