Testosterone is a key hormone that affects many bodily functions, including sperm production, maintaining bone density, and more.
An imbalance in Testosterone can have distressing effects such as Erectile Dysfunction, loss of sex drive, and loss of hair.
While all these are common symptoms of low Testosterone, taking Testosterone Replacement Therapy (TRT) for treatment can also have some side effects.
But is loss of hair a side effect of TRT?
This article will attempt to answer the question: ‘Does Testosterone cause hair loss?’ We will also discuss ways to prevent hair loss.
Does Testosterone Cause Hair Loss
Firstly, you should know that there are two kinds of Testosterone: DihydroTestosterone (DHT) and ‘free’ Testosterone.
Testosterone is converted into DHT by an enzyme called 5 alpha-reductase. DHT is a more potent form of Testosterone used by the body in the skin, prostate, and hair follicles.
Increased DHT activity at the hair follicles can cause hair loss by shortening the hair cycle. DHT can shrink the hair follicles, resulting in thinner and shorter hair.
Ultimately, the hair is not able to grow out of the follicle, leading to hair loss.
Also, people diagnosed with Low Testosterone (low T) may take Testosterone Replacement Therapy (TRT) to boost Testosterone levels.
TRT may involve using Testosterone gels, patches, or pills like Cernos.
TRT increases the availability of Testosterone to be converted into DHT, which can result in hair loss.
Overall, Testosterone can cause hair loss by converting into DHT.

Other Potential Side Effects of Testosterone
Testosterone Replacement Therapy can relieve low Testosterone symptoms by increasing T levels in the body.
It can have several positive effects, such as improving sex drive and bone density. But TRT can also result in side effects such as:
- Reduced sperm count
- Elevated risk of heart disease
- Worsening of heart failure
- Enlarged prostate
- Increased cholesterol levels
- Increased risk of blood clots
- Difficulty falling asleep or staying asleep
There is a higher risk of TRT side effects in people with cardiovascular disease. But, it is unclear whether TRT enhances the risk of stroke, heart attack, and prostate cancer.
You should note that it is not necessary for you to face any or all of these side effects of Testosterone or TRT.
Consult a doctor before taking TRT to understand the side effects of Testosterone better.
How to Prevent Hair Loss
It can be extremely frustrating to deal with hair caused by high Testosterone levels or aging.
Fortunately, medicines like Finasteride can promote scalp hair growth. For this reason, your doctor may recommend it, though it is mainly known to treat Benign Prostatic Hyperplasia.
Finasteride inhibits the conversion of Testosterone into DHT, thereby helping to prevent hair loss.
However, Finasteride is not meant for use in females, especially those who are pregnant or planning to get pregnant.
Lifestyle changes may also help you prevent hair loss by restoring hormonal balance. These changes may include stress management, a balanced and healthy diet, and regular exercise.
If you are concerned about extreme hair loss, consult a dermatologist or doctor for personalized advice.

Summing Up
Testosterone is a key hormone regulating sex drive, bone density, and more. An imbalance in Testosterone levels (T levels) can result in loss of sex drive, Anxiety, fatigue, etc.
Some people also experience hair loss when they have low T or start taking Testosterone Replacement Therapy (TRT) to boost T levels.
Now, you may be wondering, ‘Does Testosterone cause hair loss?’
DHT, a more potent form of Testosterone, can cause hair loss. It can cause the hair follicles to shrink and shorten the hair growth cycle, resulting in hair loss.
TRT may cause hair loss by increasing the availability of Testosterone that can be converted into DHT. Higher DHT means higher activity of DHT at the hair follicles, leading to hair loss.
Apart from this, TRT can also cause side effects such as enlarged prostate, reduced sperm count, and sleep problems.
It is advisable to consult a healthcare professional before taking TRT to understand the risk of side effects.
If you experience hair loss due to TRT or high DHT, consider taking medicines like Finasteride. It can inhibit the conversion of Testosterone into DHT, thereby preventing hair loss.
Lifestyle changes such as a balanced diet and regular exercise can also help reduce hair loss.
Consult a medical practitioner if you experience hair loss for personalized advice.
