Female Hair Loss Blood Test: Tackling Genetics, Health Conditions & Medication

Navigating the complexities of female hair loss requires an understanding of the various factors at play, from the genetic blueprints you inherit to the health conditions you may encounter and the medications you might need. For many women, hair loss isn't just a standalone issue but a symptom intertwined with a web of genetics, health, and lifestyle factors.

Recognising these challenges, One Day Tests offers the Female Hair Loss Blood Test, a tool designed not just to uncover the causes behind hair loss but to empower women with actionable insights. This test serves as a proactive measure for those who are aware of their family's hair history or their health conditions and wish to better understand how these factors may influence their hair health. It's about moving beyond worry to action, using precise insights to inform decisions that promote healthier hair.

The Genetic Link

Genetics play a significant role in determining the health and longevity of your hair. Conditions such as Female Pattern Hair Loss (FPHL) are influenced by hereditary factors, making those with a family history more susceptible.

However, it's crucial to understand that inheriting a predisposition to hair loss doesn't seal your fate. The expression of genetic hair loss is influenced by a multitude of factors, including hormones, nutrition, and lifestyle choices.

The key to managing and potentially mitigating the impact of genetic hair loss lies in early monitoring and proactive intervention. By staying vigilant about changes in your hair's thickness, texture, and overall health, you can promptly identify any concerning signs. This awareness enables you to seek professional advice and take timely action.

Health Conditions That Influence Hair Health

Several health conditions can significantly impact hair health, leading to thinning, loss, or changes in hair texture. Among these, Polycystic Ovary Syndrome (PCOS) and thyroid disorders stand out due to their direct link to hormonal imbalances, which can affect the life cycle of hair follicles.

Androgenetic Alopecia

Often referred to as female pattern hair loss, Androgenetic Alopecia is a hereditary condition influenced by genetics, hormones, and ageing. It's characterised by a progressive thinning of hair in a pattern distribution on the scalp. Androgens, though typically considered male hormones, are present in all women and play a significant role in hair growth and loss.

Polycystic Ovary Syndrome (PCOS)

PCOS is a common condition affecting women of reproductive age, characterised by hormonal imbalances that can lead to a variety of symptoms, one of which includes hair thinning or hair loss on the scalp. This condition can also cause excess hair growth in areas typically seen in males (hirsutism) due to increased androgen levels. Women with PCOS may observe their hair becoming thinner or receding in a pattern similar to male pattern baldness.

Thyroid Disorders

Encompassing both hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid), thyroid disorders can also manifest through hair loss. The thyroid gland plays a crucial role in regulating metabolism, energy, and growth, including the growth of hair follicles. When thyroid hormone levels are too low or too high, it can disrupt the normal cycle of hair growth, leading to hair loss. Typically, this type of hair loss involves uniform thinning across the scalp rather than bald patches.


Particularly iron-deficiency anaemia, anaemia is a common condition where the body lacks enough healthy red blood cells to carry adequate oxygen to its tissues. This deficiency can have a profound impact on many bodily functions, including hair growth. Hair follicles require a rich supply of oxygenated blood to maintain their rapid growth cycle. When iron levels are low, hair growth can be stunted, leading to increased shedding and overall hair thinning.

Navigating Medication-Induced Hair Loss

While medications are often essential for managing health conditions, it's important to recognise that some can have side effects that impact hair health, leading to thinning or loss.

Several types of medications can contribute to hair thinning or loss as a side effect. For instance:

  • Hormonal therapies, including birth control pills and hormone replacement therapy, can alter the body's hormonal balance, potentially leading to hair loss for those susceptible.

  • Medications for chronic conditions such as blood pressure regulators, antidepressants, and anticoagulants have been known to affect hair growth cycles, resulting in hair shedding or thinning.

  • Treatments like chemotherapy, aimed at targeting rapidly dividing cancer cells, unfortunately also affect rapidly growing hair follicles, leading to significant hair loss.

Understanding the potential for these side effects is crucial, not as a deterrent from necessary medication but as a component of comprehensive health management.
