Worldwide, 85% of Men (15% women) suffer from hair loss. Day by day, the number of hair loss
sufferers is increasing in number and is more than doubled between 2008 to 2010. The importance
of hair in our lives cannot be overstated. Whether men or women lose their hair, they lose much
more than their natural, youthful appearance. People also lose their self-esteem and self-
confidence associated with healthy looking hair. The scalp and hair requires an optimal amount of
nutrients that is not always provided by the daily nutritional intake leading to Hair. Hair growth
actives have a strong presence in our everyday lives and are integrated to help prevent hair loss
and nurture hair regrowth.
KOPYRROL recovers weak follicle cells by supplying the nutrition which hair needed for growth and
increase the growth of hair and increases the volume of hair in the growth stage by working on the
deep structure of the roots. Through the bloodstream, KOPYRROL works at the level of the hair
root, which is responsible for a healthy scalp and beautiful hair. KOPYRROL is used in hair cosmetics
to combat hair loss due to premature exhaustion of the hair root.

Mechanism of Hair Growth Cycle
The scalp has at an average 100,000 hairs. A healthy scalp sheds hair continuously and new hair replaces them.
Hair growth follows a series of cycle. Each cycle includes a growth phase (anagen), a transitional phase
(catagen), and a resting phase (telogen). Any changes to the normal hair growth cycle would result in hair loss. It
occurs when the old hairs are shed and no new hair is growing from beneath to replace it. However, when the
scalp is not able to produce new hair to replace the shed hair, baldness develops and the condition is
scientifically called as alopecia.
The most common type of hair loss is androgenetic alopecic (AGA) both in men (Male pattern baldness)
and women (Female pattern hair loss) and is caused by heredity hormones and genetics.
* Everyday around 100 old hairs are shed before new hair replaces them. Average hair growth rate is upto 1cm per
month
Mechanism of KOPYRROL on stimulating hair growth
Altered Hair Growth Cycle
Decrease A: T
• Miniaturization of follicles
• Gradually Shorter Anagen Phase &
longer telogen phase
• Empty follicles- Disruption of hair cycle
Normal Hair Growth Cycle
Normal A: T (80:20)
Return to Anagen: The
hair follicle re-enters
the growth phase. The
older hair is shed, and
then replaced by a new
one.
Multiplication of group of
cells at the base of the
hair. Typically lasts from 2
to 6 years.
The growth in the hair
follicles stops and
degeneration begins. This
phase lasts about 2 to 3
weeks.
The hair rests and no growth
is experienced which lasts 2
to 3 months.
