Male Pattern Hair Loss Causes: What Causes Male Pattern Hair Loss? and Hair Loss Causes

Male pattern hair loss, also called androgenetic alopecia, is the most common form of hair loss in men. It is not usually a single event in which hair suddenly falls out. Instead, follicles in certain scalp areas gradually produce hairs that are finer, shorter and less visible. The British Association of Dermatologists describes a combination of genetic and hormonal factors, including the effect of dihydrotestosterone (DHT) on susceptible follicles, in this gradual process [2]. That description helps explain why a person may first notice more scalp showing through under bright light, a broader part at the front, or styling that no longer creates the same coverage.

The question is personal because progression is variable. One man may notice a slowly changing hairline in his twenties, while another first sees reduced density at the crown much later. Relatives with a similar pattern can be useful context, but a family history does not predict an identical age of onset or extent. The practical task is to observe the distribution and pace without jumping to conclusions from a single haircut, photograph, or handful of shed hairs. For a fuller discussion of overlapping concerns, see causes of thinning hair in men.

Hair loss causes are broader than male pattern baldness. The NHS lists illness, stress, cancer treatment, weight loss and iron deficiency among possible causes of temporary hair loss, while Hong Kong’s Centre for Health Protection also lists certain diseases, scalp infection or skin damage, some medicines and poor nutrition [1] [4]. These are not interchangeable explanations. A recent fever or operation, for example, belongs in the timeline; so do dietary change, a new prescription, and persistent scalp symptoms. The point is not to blame yourself for every change in routine, but to provide enough context for a sensible assessment.

Pattern and tempo help organise the possibilities. Gradual thinning concentrated at the temples, hairline and crown is more consistent with male pattern loss than a sudden all-over shed. Even so, people can have more than one factor at once. Someone with early hereditary thinning may also experience a temporary period of increased shedding after illness or a restrictive diet. Asking only, ‘Is it genetic?’ can miss that distinction. Asking, ‘What changed, where is it happening, and how fast?’ produces a much clearer starting point for you and the clinician.

Traditional Chinese medicine approaches hair concerns by asking about the person’s wider state, daily routines and accompanying symptoms. Terms such as liver-kidney deficiency or damp-heat may be used as traditional pattern concepts during a consultation. They are not established modern mechanisms of follicle miniaturisation, and they do not diagnose androgenetic alopecia. Keeping that distinction clear is respectful of both systems: a traditional discussion may help organise a Chinese medicine consultation, while a history and scalp examination remain important when identifying the medical cause of hair loss.

For someone considering Chinese medicine, the most useful first conversation is specific. Describe whether the concern is a slow receding hairline, crown thinning, diffuse shedding, breakage, oiliness, itch, flaking, discomfort or a visible patch. Include when it began, changes in sleep, diet, stress, illness and medication, plus any prior medical assessment. Do not stop prescribed treatments or postpone review for sudden or patchy loss in order to try herbs or acupuncture. Evidence for Chinese medicine interventions for hair loss is limited and may not apply to an individual; any option should follow an in-person discussion, not a generic online recipe.
