Progesterone For Men

Progesterone, a hormone often solely linked to menstrual cycles and pregnancy, is gaining recognition for its role in hair growth. This blog delves into the scientific mechanisms behind this, exploring how progesterone interacts with other hormones like testosterone and DHT. We'll also discuss the off-label benefits of using progesterone in a hair growth protocol.

Steroid Hormone Pathways: A Brief Overview

Steroid hormones like progesterone, testosterone, and DHT (Dihydrotestosterone) share common precursors and are part of complex biochemical pathways. To better understand how they interplay, let's examine the steroidogenesis pathway briefly:

  1. Cholesterol is the precursor for all steroid hormones.
  2. Pregnenolone is formed from cholesterol and can lead to the formation of either progesterone or DHEA.
  3. Progesterone can convert to other hormones like cortisol or aldosterone but is also an end hormone itself.
  4. Testosterone stems from DHEA and can either convert to estrogen via aromatization or to DHT via 5-alpha-reductase.

In summary, the steroid hormones are interconnected, and changes in levels of one hormone can influence others.

Mechanism of Action

Progesterone serves multiple roles in the body, including fertility and mood regulation. When discussing hair growth, progesterone's primary function is to block the conversion of testosterone to DHT. DHT is more potent than testosterone and is often associated with hair loss. By limiting the amount of DHT formed, progesterone not only helps to maintain hair but also allows for higher circulating levels of beneficial testosterone.

Off-Label Benefits for Hair Growth

Progesterone is not FDA-approved for hair growth, but its application in this realm is promising. An off-label protocol using a 10 mg dosage has reported improvements in hair density and volume. The reduction in DHT and the maintenance of testosterone levels make it a valuable addition to hair growth protocols.

Risks and Side Effects

Though well-tolerated, progesterone can have side effects such as dizziness, nausea, and headaches. It may interact with other medications, so consultation with a healthcare provider is advised.


A 10-25 mg dosage is often used in hair growth protocols, generally as part of a broader treatment plan.


People with liver disease, certain types of cancers, or other specific medical conditions should avoid progesterone supplementation.


The role of progesterone in hair growth is emerging as an exciting research avenue. Its interaction with testosterone and DHT is pivotal, especially when viewed in the context of the complex steroid hormone pathway. While not FDA-approved for hair growth, early evidence and off-label use make progesterone an intriguing option for those grappling with hair loss.
