What is nutritional deficiency alopecia?
Nutritional deficiency alopecia is hair loss caused by a lack of essential vitamins and minerals such as iron, zinc, vitamin D, or biotin.
It often manifests as diffuse thinning and can be reversed with proper dietary correction and supplementation.
Red light therapy supports recovery by improving cellular metabolism and follicle resilience, but addressing the underlying nutritional gaps is essential for long-term improvement.
