research Role of scalp health in achieving optimal hair growth and retention
Healthy scalp leads to better hair quality and less damage.
research DNA determination of human hair bulbs in normal and androgenetic alopecia
Hair loss happens due to faster cell growth and fewer cells in affected follicles.
