Hair-loss is defined by more than 100 strands falling from the roots per day due to the hardening of collagen hair shaft. Hair-fall is defined by more than 100 strands per day falling from the roots due to biological reasons such as stress, hormones, diet... AND by hair falling from breakage. Hair breakage is due to mechanical stressors such as brushing and excessive styling.

Genesis offers a dual benefit for women experiencing hair-fall: reducing hair-fall from the roots and hair-fall from breakage. Resistance is for damaged to very damaged hair from chemical aggression.
