Top 10 Culprits Behind
Hair Loss Revealed
Our extensive blood tests reveal the underlying causes of your hair loss, paving the way for precise and effective solutions. By pinpointing factors such as hormonal imbalances, nutritional deficiencies, or other underlying issues, we create a personalised treatment plan tailored specifically to you. This approach ensures you receive the most relevant and impactful care for optimal hair restoration.
Beyond the usual suspects, blood tests can uncover less obvious factors affecting hair loss. Hormonal imbalances, often linked to conditions like polycystic ovary syndrome (PCOS), may leave distinctive markers in your blood chemistry. Similarly, autoimmune conditions like alopecia areata can be identified through specific indicators. Even systemic issues, such as liver or kidney disease, can reveal traces that affect hair health. By interpreting these intricate clues, we can craft a customized treatment plan targeting the unique contributors to your hair loss, paving the way for successful restoration.
Iron Deficiency Anaemia
Iron deficiency anaemia occurs when the body lacks sufficient iron, decreasing red blood cell production. As red blood cells transport oxygen to the scalp and hair follicles, a deficiency can weaken hair, making it more susceptible to falling out. Restoring iron levels can enhance hair health and promote growth.
Vitamin D Deficiency
Blood tests for hair loss can provide crucial insights, such as detecting a vitamin D deficiency. Vitamin D plays a vital role in stimulating both new and existing hair follicles. Identifying this deficiency allows for vitamin D supplementation, potentially reversing hair loss by tackling its root cause.
Thyroid disorders
Hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid) can lead to hair loss by disrupting the normal hair growth cycle. Thyroid hormones play a vital role in regulating metabolism, which includes maintaining healthy hair growth. Effectively managing thyroid disorders often results in the restoration of healthy hair growth.
Vitamin B12 Deficiency
Vitamin B12 is crucial for the formation of healthy red blood cells and the proper functioning of the nervous system. A deficiency in this essential nutrient can result in hair loss, along with general weakness and fatigue. Maintaining adequate B12 levels may support hair regrowth.
Hormonal imbalances
Hormonal imbalances can profoundly impact hair growth and health. For instance, PCOS may lead to thinning hair on the scalp due to increased androgen levels. Addressing the hormonal imbalance often enhances hair density.
Autoimmune Diseases
In autoimmune diseases such as lupus, the immune system erroneously targets healthy tissues, including those in the scalp, potentially causing hair loss. By managing lupus and other autoimmune disorders, hair loss can be mitigated. It is crucial, however, to work closely with a healthcare provider.
Chronic Illness
Chronic illnesses can strain the body and disrupt hair growth cycles, causing hair loss. Blood tests for hair loss allow healthcare professionals to accurately diagnose the underlying condition, facilitating effective management and significantly improving hair health.
Folic acid Deficiency
Folic acid, also known as folate, is a vital B vitamin essential for cell growth and metabolism—both crucial processes for maintaining healthy hair follicles. A deficiency in folic acid can result in premature greying and hair loss as the body struggles to produce and sustain healthy hair cells.
Telogen Effluvium
Effluvium is frequently prompted by stress, major life events, or severe illness, leading to widespread hair thinning. The condition arises when numerous hair follicles prematurely enter the telogen (resting) phase of the hair cycle, resulting in increased shedding and thinning.
Alopecia Areata
An autoimmune disorder causes the immune system to attack hair follicles, leading to hair loss in small patches. Although the exact cause remains unknown, it is thought to result from a combination of genetic and environmental factors. Treatment can expedite hair regrowth.
