Well,
the
question
could be
reframed
as 'when
does the
falling
of hair
be of
concern?'
This is
because,
medically,
some
amount
of hair
falling
has been
considered
'normal'.
Hair
being an
appendage
of the
body
like
nails,
they
grow and
fall
constantly,
in
varying
degree.

How Much
of Hair
Falling
Per Day
is
Normal?
Medically
speaking,
for an
adult,
about 40
to 80
hair
falling
a day is
considered
within a
normal
range.
It
simply
means
that one
may not
consider
getting
treated
for it
if this
is the
case.
However,
it is
also
important
that if
one
observes
sudden
increase
of hair
falling
even
within
the
normal
range,
it calls
for
medical
attention
and
evaluation.
Again,
if one
has hair
falling
within
normal
range
but if
they
fall
from the
roots
amounting
to a
definite
reduction
in the
quantum
of the
total
hair on
the
scalp,
it calls
for
appropriate
treatment.
In any
case,
consistent
hair
falling
over 80
a day
and/or
reduced
hair
quantum
needs to
be
evaluated
for
treatment.

Normal
growth
cycle of
hair:
Anagen/
The
growing
phase:
In this
phase,
the hair
grows
rapidly
from the
follicle.
This
phase
usually
lasts
for
about
1000
days;
however,
it may
range
form 2
to 6
years.
Longer
the
anagen
phase,
the
longer
the hair
will
grow.
Catagen/
Hair
growth
stoppage:
This is
a
regressive
phase
lasting
for
about 2
weeks.
In this
phase,
the hair
stops
growing,
the
follicle
shrinks
and part
of it
may die.
Telogen/
Resting
phase:
This is
the
final
resting
end
phase of
hair
growth
cycle;
no
further
change
occurs
now.
This
phase
may last
for
about 2
to 4
months.
Later
on, the
hair
follicle
becomes
active
again
developing
new hair
and
forcing
old
Telogen
hair
out. At
any
given
time,
90% of
hair is
in
Anagen
phase
and 10%
in
Telogen
phase. A
reversal
of the
ratio
results
in
thinning
of hair.
