Hair loss can be stressful. Seeing extra hair on your pillow, in the shower, or on your brush can make you wonder what is causing it. Many people ask how testosterone affects hair growth and whether it can help or lead to more hair loss.
Testosterone can increase hair growth in areas like the beard and body. However, it does not usually make scalp hair grow thicker. In some people, it can contribute to thinning hair because of how the body responds to certain hormones.
In this guide, Dynamic Spine & Sport Rehabilitation explains the connection between testosterone and hair growth and how red light therapy may help support healthier hair.
Does Increasing Testosterone Increase Hair Growth?
Increasing testosterone does not usually make scalp hair grow thicker or faster. Testosterone affects different types of hair in different ways. Testosterone can increase:
- Beard growth
- Chest and body hair
- Muscle growth
- Energy levels
Scalp hair responds differently. In some people, the body changes testosterone into a hormone called dihydrotestosterone (DHT). If someone is sensitive to DHT, it can affect their hair follicles.
DHT can make hair follicles smaller over time. Smaller follicles produce thinner hair and may eventually stop growing new hair. This is why some people can have high testosterone levels, thick body hair, and still experience thinning hair on their scalp.

- Promotes relaxation
- Boosts circulation

Can Low Testosterone Cause Hair Loss?
Low testosterone is not usually the main reason for scalp hair loss. The most common type of hair loss, called male pattern baldness, usually happens because of genetics and sensitivity to a hormone called DHT.
If you notice sudden or unusual hair loss, low testosterone may not be the only possible cause. Stress, nutrition problems, thyroid issues, medications, and scalp conditions can also affect hair growth. Finding the real cause can help you choose the right treatment.
How to Support Healthy Testosterone Levels for Hair Growth?
Healthy testosterone levels help your body function properly, but higher testosterone does not always improve hair growth. A healthy lifestyle can help your body maintain balanced hormone levels. Ways to support healthy testosterone levels include:
Lifestyle Habit | How It Helps |
Eat a balanced diet | Foods with zinc, vitamin D, and healthy fats, such as eggs, salmon, nuts, and leafy greens, help support normal hormone production. |
Exercise regularly | Strength training and high-intensity workouts may help support healthy testosterone levels and improve overall health. |
Get enough sleep | Seven to eight hours of quality sleep each night helps your body produce important hormones and maintain balance. |
Reduce stress | High stress can affect hormone levels. Activities like walking, meditation, and yoga may help lower stress. |
Limit alcohol | Too much alcohol can affect testosterone production. Drinking less can help support healthier hormone levels. |
Can Red Light Therapy Help Hair Growth?
Yes, red light therapy has become a popular non-invasive option for people who want to support hair health. This treatment uses red and near-infrared light to reach the scalp and support normal cell activity.
The light may help hair follicles by:
- Supporting cellular energy production
- Improving scalp circulation
- Helping follicles stay in the active growth phase
- Reducing scalp inflammation
Red light therapy works best for people with early or moderate hair thinning. It may help improve hair thickness and density, but it cannot always restore hair in areas where follicles are no longer active.
Is Red Light Therapy Effective and Safe for Hair Growth?
Red light therapy may help some people with certain types of hair loss. This treatment uses low-level red and near-infrared light to support hair follicles and help them stay active.
Studies suggest that low-level light therapy (LLLT) may help:
- Increase hair density
- Improve hair thickness
- Support healthier hair follicles
- Slow down hair thinning in some people
However, results are different for everyone. Red light therapy works better when the hair follicles are still active. It may not restore hair in areas where follicles have stopped working completely.
Red light therapy is generally safe when people use it correctly. Most side effects are mild and temporary. Some people may notice scalp warmth, slight redness, dryness, or mild irritation after treatment.

- Supports healthier hair follicles

How to Use Red Light Therapy for Hair Growth
A provider creates a treatment plan based on your hair condition and goals. The steps usually include checking your scalp, choosing the right settings, applying the light treatment, and following a regular schedule. Here are the steps:
- A provider checks your scalp and hair condition to see if red light therapy is a good option for you.
- The provider chooses the right device settings, light strength, and treatment time based on your needs.
- The provider places the device over areas with thinning hair to deliver light to the scalp.
- The provider follows a treatment schedule with regular sessions to support better results.
How Often Should You Use Red Light Therapy for Hair Growth?
The number of red light therapy sessions you need depends on the device, treatment plan, and your hair condition. Most people need regular sessions for several months to see noticeable changes.
Common treatment schedules include:
- At-home devices: Use for about 10 to 15 minutes per session, three to five times per week.
- Professional clinic treatments: Sessions often take 20 to 30 minutes and may be recommended two to three times per week, depending on your needs and the device used.
Consistency is important because hair growth takes time. Skipping sessions may slow your progress, so follow the recommended schedule and give the treatment enough time to work.
Final Thoughts
Testosterone and hair growth are connected, but the effect depends on the type of hair. Testosterone may increase body hair, but it does not usually make scalp hair grow thicker. In some people, DHT sensitivity can lead to hair thinning and hair loss. Treatments like red light therapy may help support healthier hair and scalp health.
