WHAT IS LOSS OF DENSITY ?
A reduction in the overall mass of your hair.
1 . YOUR HAIR DENSITY DECREASES
With age, hair becomes visibly thinner, hair density, in other words the number of hairs per cm² on the scalp's surface, tends to decrease leading to hair that appears impoverished and sparse.
2 . IN CONCLUSION: IMPOVERISHMENT OF THE HAIR
A reduction of approximately 30% in the diameter of each individual hair fibre associated with a diminution of 30% of the hair's density leading to impoverishment of the hair (40% less hair coverage).
