According to trichologist and Nioxin ambassador Mark Blake, these are the most common causes.

·       Genetics: This type of hair loss is known as androgenetic alopecia. 

·       Health: If you are unwell this has a massive impact on your hair. Inflammation within the body is a common cause of hair loss, as are conditions such as thyroid disorders and autoimmune diseases. 

·       Nutrition: The hair follicle requires a lot of energy to grow optimal hair hence why good nutritional health is vital. 

·       Stress: This increases the body’s production of adrenaline and cortisol (our ‘fight or flight’ hormones), disrupting the hair’s natural growth cycle and leading to excessive shedding. 

·       Medication: Some prescription drugs can stop the absorption of certain nutrients. 

·       Menopause: Can lead to miniaturisation of the hair follicle leading to hair thinning, hair breakage, or hair loss. Some hair follicles are particularly sensitive to androgens, a group of hormones that include testosterone and androstenedione. During the onset of the menopause, oestrogen levels start to fall, and the balance is disrupted between oestrogen and testosterone.
