Examination to Identify Hair Loss Causes Through Internal Body Changes Blood Test

It is needed when hair loss starts suddenly, when treatment effects are inconsistent, or after childbirth or dieting. It is also recommended when fatigue or physical condition changes frequently, or when there is a history of internal medical conditions, to identify internal causes of hair loss.

A blood test evaluates systemic factors affecting hair follicle growth and maintenance, such as hormonal status, nutritional status, and metabolic and inflammatory conditions. It helps determine whether hair loss originates from internal bodily changes rather than external factors.

A blood test does not directly determine the exact cause of hair loss, but it helps identify internal medical factors that trigger or worsen hair loss. For example, it can check whether iron deficiency, thyroid dysfunction, hormonal imbalance, or nutritional deficiencies are affecting hair loss.

If internal medical causes exist, repeating scalp treatment alone may have limited effectiveness. Therefore, it is important to establish treatment priority through blood testing. This helps reduce unnecessary treatment and determine an appropriate direction based on the current condition.

Through the results, it can be determined whether full-body management is required, whether treatment should be combined, whether lifestyle correction alone is sufficient, or whether certain treatments should be delayed. In other words, it allows the establishment of long-term treatment and management strategies based on internal causes of hair loss.
