What Men Should Know About Hormone-Related Hair Loss
Hair loss affects many men, not just in old age, but often from their mid-20s. While slight hair loss is natural, severe or premature hair loss can be a sign of hormonal changes, genetic predisposition, or metabolic disorders.
The most common form is androgenetic alopecia, which is genetically determined, hormonally controlled loss of scalp hair. However, other causes such as thyroid problems, iron deficiency, stress, or testosterone imbalances can also play a role. Those who want to preserve their hair long-term should therefore not only approach the cause cosmetically but also medically.
What are the different types of hair loss?
Not all hair loss is the same. For men, the following are particularly relevant:
- Androgenetic alopecia (hereditary, hormonally influenced): Typically affects the forehead and back of the head, "receding hairline," crown baldness
- Diffuse hair loss: uniform hair loss across the entire head, often triggered by stress, infections, medication, or deficiencies
- Alopecia Areata (circular hair loss): Autoimmune form, rather rare
- Cicatricial alopecia: Destructive, with permanent hair loss – very rare
The most common cause in men is the effect of the hormone dihydrotestosterone (DHT) on sensitive hair follicles, which, given a genetic predisposition, leads to the shrinking of hair roots.
Hormonal Causes of Hair Loss
Hair reacts sensitively to the internal balance, especially to the following hormones:
- Dihydrotestosterone (DHT): Formed from testosterone, has a particularly strong effect on hair follicles
- Thyroid hormones (fT3, fT4): important for the cellular metabolism of the hair root
- Cortisol: elevated during chronic stress, can disrupt the hair cycle
- Estrogen/Progesterone (also in small amounts in men): Shifts possible due to overweight or liver strain
Especially in men with hair loss and simultaneously exhaustion, loss of libido, or poor regeneration, a comprehensive hormone test should be carried out.
When is hair loss medically relevant?
If you notice any of the following points over weeks or months, it makes sense to take a closer look:
- Significantly more than 100 hairs daily in your brush or shower
- Visible thinning on the top of the head or at the temples
- Rapid recession of the hairline within a few months
- Hair loss after significant stress (illness, crash diet, stress)
- Other symptoms such as sleep problems, fatigue, restlessness, or loss of libido
Especially the combination of hormonal complaints and visible hair loss should be taken seriously.
Diagnosis of Hair Loss: What Makes Sense?
In addition to a medical examination, a blood test is essential to identify systemic causes. Important lab parameters:
- Total and free testosterone
- DHT (Dihydrotestosterone)
- SHBG (Sex Hormone-Binding Globulin)
- TSH, fT3, fT4 (Thyroid)
- Ferritin (Iron stores)
- Zinc, Vitamin D, B vitamins
- Cortisol (morning)
- Inflammation markers (CRP, possibly Homocysteine)
The combination of these markers provides a realistic picture of your hormone balance and reveals potential deficiencies that can be treated specifically.
Tip: Use Adon Health's Premium Hormone Analysis to analyze DHT, free testosterone, thyroid, and stress axis values all at once – conveniently from home.
What can you do yourself?
In addition to medical clarification, daily life and lifestyle play a significant role in slowing down hair loss:
- Reduce stress
- Optimize nutrition - zinc, iron, vitamin D, omega-3
- Regular sleep - important for hormonal stability
- Exercise & endurance training
- Avoid aggressive shampoos, heat, synthetic styling products
For androgenetic alopecia, medical measures such as finasteride, minoxidil, or hair transplantation can also be considered – always in consultation with a doctor.
Conclusion
Hair loss is often a visible sign of an internal imbalance, especially hormonal. Instead of just treating superficially, you should look for the causes: Is your testosterone optimal? Is your DHT too high? Are you lacking thyroid hormones or vital nutrients?
Tip: With Adon Health's Premium Hormone Analysis, you get a comprehensive insight into your hormone status – free testosterone, thyroid, and more.
You can also have your lab values determined by your family doctor, specialists, or in direct laboratories.
