What is hair density?
Hair density refers to the number of individual hair strands per square centimeter of scalp. It’s a key measurement used to assess hair health and determine the severity of hair thinning.
Lower density can result from genetic factors, inflammation, hormonal imbalances, or damage to hair follicles. It affects the overall appearance of fullness and coverage.
Red light therapy may help increase hair density by stimulating blood flow and energy production within the scalp, which can promote the activity of dormant follicles and improve visible volume over time.
