Hair loss can result from a range of factors, including genetics, medical conditions, hormonal changes, and certain medications or treatments. Here are some common causes:

Genetics (hereditary hair loss): Also known as male pattern baldness (androgenetic alopecia). This is the most common cause of hair loss in men. It often worsens with age and is typically seen as a receding hairline and/or thinning at the crown.
Medical conditions: Hair loss can be triggered by conditions such as alopecia areata (an immune-related cause of patchy hair loss), telogen effluvium (often temporary and linked to stress or illness), and trichotillomania (compulsive hair pulling).
Hormonal changes: Hormone fluctuations can contribute to hair loss. For example, thyroid hormone changes or sensitivity to androgens like dihydrotestosterone (DHT) can play a role in male pattern baldness.
Medications and treatments: Some medicines (including certain cancer treatments) can cause hair loss as a side effect. Traction from tight hairstyles can also contribute to shedding.

Totiva’s online assessment helps identify the most likely cause of your hair loss and whether treatment is appropriate. If your hair loss is sudden, patchy, or associated with other symptoms, we may advise you to speak to your GP or a dermatologist.
