Understanding excessive hair shedding and internal health

Hair loss and thinning is a normal part of ageing, however sometimes excessive hair shedding can be the first indication of an internal health problem. 

Hair loss can develop gradually over years or it may happen abruptly. Depending on the underlying cause it may be temporary or permanent. 

The good news is; diet, supplements and lifestyle changes may positively affect these conditions and in many instances hair can grow back once the treatment has been implemented. 

Endocrine Disorders 

PCOS (Polycystic ovary syndrome): Excess androgens in females can be a cause of female pattern hair loss. The excess androgens causes weak follicles leading to excess hair shedding on the scalp and it is usually seen as a widening of hair parting. 

Hyperthyroidism and Hypothyroidism: Thyroid hormones regulate nearly every function in the body, including hair grown and for this reason may contribute to hair loss. Supporting the dysfunction and correcting imbalances in both PCOS and Thyroid conditions will result in hair regrowth. 

Diabetes: Hair loss can be a symptom of both type 1 and type 2 diabetes and is thought to have a few possible causes, including hormonal imbalances, poor circulation due to hyperglycemia, or an autoimmune disorder. Hair loss can often be reversed with medications and by getting blood sugar levels under control through diet and lifestyle interventions. 

Nutritional deficiencies: Macronutrients, vitamins and minerals deficiencies can lead to hair loss and diminish the hair growth as they are required in the hair growth cycle and necessary for cellular turnover. 

Protein and Iron are the most common deficiencies associated with excess hair shedding. Once the deficiency has been corrected a hair shedding will stop. 

Postpartum hair loss: Due to the hormonal shifts excess hair shedding usually occurs 4-6 months after birth. Losing hair after giving birth isn’t preventable and some women are affected more than others however this hair loss will correct itself. 

Drug induced hair loss: Certain medications cause hair loss. Hair may recover once the body has adjusted to the medication or may continue for as long as it is taken. 

Stress: Hair loss can be triggered by an intense amount of stress. Some examples include;

• After a fever or illness 

• Undergoing surgery 

• Food poisoning 

• Chronic emotional stress 

Excessive hair shedding should stop 2-3 months after a stressful event. 

Crash dieting: Poor nutrition or severely restricting diets can lead to all sorts of nutrient deficiencies, and stress on the body which for reasons discussed previously will result in slow hair growth and thinning.
