Of the 100,000 to 350,000 follicles on the human scalp, not all are productive.

The hair grows for around 1,000 days (3 years) and then rests for a period of 100 days (3 months.). This “Hair Cycle” varies between individuals and is influenced by age, diet and state of health. The old hair from the last “Hair Cycle” may remain in the follicle and not be dislodged by daily hair care products, but it will be displaced by the new hair as it grows up the follicle. Hair length is controlled by the length of the growing phase which is Anagen.

The stronger the follicle (dermal papilla), the longer the hair will grow. Weak hair roots (dermal papilla) render the hair not only unable to grow longer, they are not able to hold on to the hair, Therefore they get detached. We all lose hair naturally everyday. As long as new hair are produced at the same rate as those falling out, there will be no difference in the density of the hair. But if shedding is greater than production, hair loss ensues. Hair thickness varies between individuals. Some finer while others coarser. As we grow older, there is a tendency for our hair fibres to become finer and shorter over excessive cycles.
