    diagnostic technique using photos to assess hair growth

    A phototrichogram is a diagnostic technique used to assess hair growth and hair loss. It involves taking high-resolution photographs of a marked area of the scalp before and after shaving the hair in that area. By analyzing these images, professionals can evaluate hair density, hair growth rate, and the proportion of hair in different growth phases, which is useful for diagnosing conditions like alopecia and monitoring the effectiveness of treatments.
