Professional hairdressers can offer a number of different types of perm that
are not available for home use.
|
|
|
 |
Acid perms
|
|
produce highly conditioned, flexible curls.They are
ideally suited to hair that is fine, sensitive, fragile, damaged, or tinted, as
they have a mildly acidic action that minimizes the risk of hair damage.
|
|
|
|
|
|
Alkaline perms
|
|
Alkaline perms give strong, firm curl results on normal and resistant
hair.
|
|
|
|
|
Exothermic perms
|
|
Exothermic perms give bouncy, resilient curls."Exothermic"
refers to the gentle heat that is produced by the chemical reaction that occurs
when the lotion is mixed.The heat allows the lotion to penetrate the hair
cuticle, conditioning and strengthening the hair from inside as the lotion
moulds the hair into its new shape.

PERMING TECHNIQUES
|
|
Any of the above types of perm can be used with different techniques to
produce a number of results.
|
|
|
|
Body perms
are very soft, loose perms created by using large curlers,
or sometimes rollers.The result is added volume with a hint of wave and
movement rather than curls.
|
|
|
|
Root perms
add lift and volume to the root area only.They give
height and fullness, and are therefore ideal for short hair that tends to go
flat.
|
|
|
|
Pain curl perms
give soft, natural waves and curls, which are achieved
by perming small sections of hair that have been pinned into pre-formed curls.
|
|
|
|
Stack perms
give curl and volume to one-length hair cuts by means of
different sized curlers.The hair on top of the head is left unpermed
while the middle and ends have curl and movement.
|
|
|
|
Spiral perms
create romantic spiral curls, an effect that is produced
by winding the hair around special long curlers.The mass of curls makes
long hair look much thicker.
|
|
|
|
Spot perms give support only on the area to which they are applied.For example, if the hair needs lift the perm is applied just on the crown.They can also be used on the fringe or side areas around the face.
|
|
|
|
Weave perms involve perming certain sections of hair and leaving the
rest straight to give a mixture of texture and natural looking body and bounce,
particularly on areas around the face such as the fringe.
|
|
|
|
RE-GROWTH PROBLEM
When a perm is growing out the areas of new growth can be permed if a barrier
is created between old and new growth.The barrier can be a special cream
or a plastic protector, both of which effectively prevent the perming lotion and
neutralizer from touching previously permed areas.
|
|
|
|
|
There are also products that facilitate re-perming an entire length of hair
without damaging the structure.These more complex solutions are only
available from salons.
