We all know at least one person who struggles with hair loss, if not many more. Hair loss is a common concern, sometimes close to home, affecting millions worldwide.
Research show that approximately 50 million men and 30 million women experience hereditary hair loss in the United States alone. The most common type of hair loss is called androgenic alopecia, a hereditary form of hair loss that affects both genders.

About 25% of men begin to bald by the time they are 30, and two-thirds are bald by the age of 60. Male androgenic alopecia typically starts at the temples and crown, while in women, it often manifests as thinning at the front, sides, and crown.
Globally, the hair restoration market is poised for substantial growth, with projections indicating an increase from USD 6.34 billion in 2023 to USD 9.73 billion by 2028, reflecting a robust CAGR of 8.96% during the forecast period from 2023 to 2028. These statistics show an increasing demand for advanced solutions. One emerging tool in this field is genetic testing, which provides deeper insights into the underlying causes of hair loss and offers personalized pathways to address it.
At Robgenes, we specialize in genetic testing and health programs that empower individuals to understand their unique health profiles.
In this blog, we explore 7 specific facts about genetic testing for hair loss, shedding light on its potential, limitations, and practical applications.
1. Hair loss is polygenic, not pleiotropic
If we have not explained this before, polygenic inheritance is opposite to pleiotropy because pleiotropy is the phenomenon in which a single gene influences multiple phenotypes, whereas polygenic inheritance refers to inheritance of a phenotype that is controlled by multiple genes.
Hair loss is influenced by multiple genes, making it a polygenic condition. For instance, variations in the androgen receptor (AR) gene significantly contribute to androgenetic alopecia, the most common form of hair loss. However, other genes also play a role, making genetic testing a valuable tool for uncovering this complex interplay.

2. Androgenetic alopecia affects both men and women
While male pattern baldness is widely recognized, women also experience androgenetic alopecia, often manifesting as general thinning. Studies suggest that up to 40% of women over 50 experience some degree of hair loss. Genetic testing can identify markers linked to hair follicle miniaturization in both genders. It is better to identify these markers early on.
3. Treatment plans are designed based on your DNA
Genetic testing enables the development of personal treatment plans. For example, knowing your sensitivity to androgens can guide the use of medications like finasteride or minoxidil, which are used to encourage hair growth. These two medications differ exponentially; therefore it is important to understand your own personal needs.
Advanced tools, such as the TrichoTest™, evaluate multiple genetic markers to recommend personalised solutions. A specific treatment plan ideally begins with a thorough genetic evaluation, followed by a consultation to understand the individual’s medical history and lifestyle factors. This is typically combined with targeted therapies such as oral or topical medications, dietary adjustments, and even advanced restoration techniques like PRP (platelet-rich plasma) therapy or laser treatments. The goal is to create a comprehensive and sustainable approach designed to each person’s unique needs.

4. The best time to do the test is today
Early detection is key – genetic testing allows for the early detection of predisposition to hair loss, even before visible symptoms appear. Early interventions, such as targeted therapies or lifestyle adjustments, can help mitigate progression.
Our longevity programs focus on proactive health strategies, including hair preservation.
5. The testing methods are non-evasive and no-stress
Most genetic tests for hair loss are non-invasive, typically involving either saliva samples or cheek swabs. These methods are user-friendly and straightforward, designed to minimize discomfort while maintaining high accuracy.
How it is done: After the sample collection, the process usually involves laboratory analysis of DNA to identify genetic markers linked to hair loss. Results are then provided in an easy-to-understand format, often accompanied by recommendations for personalised treatment plans or preventative measures. This streamlined and accessible approach allows a broader audience to benefit from genetic testing advancements.
6. Environmental and lifestyle factors matter more than you think
While genetics provide a blueprint, external factors like high carb and sugary diets, stress, and exposure to pollutants also influence hair health. A holistic approach combining genetic insights with environmental modifications yields the best outcomes.

7. Genetic testing has ethical questions to be answered
Genetic testing raises ethical questions, such as data privacy and psychological impact. Overall, it is a positive environment where more is gained than lost, but it’s crucial to work with trusted providers who prioritize confidentiality and provide counselling to address concerns. We tend to never ‘unhear’ what we learn from medical professions, and this can have a vast impact on our mental health as well.
At Robgenes, we ensure that your genetic data is securely managed and used responsibly. Learn about our commitment to ethical practices in all our services. We do several hair panel tests too.
Conclusion
Genetic testing has changed the way we approach hair loss, offering personalized insights that were previously unattainable.
While it’s not a standalone solution, combining genetic insights with lifestyle changes and targeted treatments can yield remarkable results.
