2- Degrees of Chemical Processes
The review of prior knowledge

First Degree: It is the minimum degree of damage that is even caused by factors
different from the processes of an aesthetics. Although the hair may not have had a
chemical service, presents this processing because after a shampoo it has
rinsed with hard water.
Hard water is saturated with heavy metals that can absorb hair.
In some cities, the drinking water service supplies this type of water, so
that the problem is very common.
Second Degree: When hair is exposed to styling products, gels,
mouse, spray, very low quality shampoo, may be the cause that the hair becomes
processes and causes damage to its structure.
This is noticeable at first glance when the hair cuticle becomes dull.
Third Grade: The indiscriminate use of the hand dryer, straighteners or curling irons
electric tools for marking, shaping or smoothing hair under heat abuse, can

Fourth Grade: In this grade, the hairs are classified into those that have been applied to.
dyes without knowing their appropriate knowledge.
When applied in their homes, they run this risk, more than anything, if they do not read their
instructions for use.
A permanentist professional is the right person to carry out a chemical process.
Sixth grade: The discoloration may be responsible for this damage.
One should not bleach without prior knowledge, using caustic soda, which
it has an approximate pH of 10 and causes an exaggerated swelling of the
cuticle, by breaking the cystine bridges and ending with more than 40% of the proteins
of the hair.
In extreme conditions, a poorly assisted process in time and form can lead to
that the stem breaks from the root or at its weakest point.
Seventh grade: It occurs when a discoloration is performed over another.
decoloration
A discoloration on a permanent straightening, the hair will suffer the
consequences up to 300% more than when the first chemical service was performed
due to not having the study and chemical knowledge of hairdressing.

Precautions to take before getting a permanent wave:
We should test:
A- Do you have dye in your hair and which one: Hair dye, tone on tone,
henna and other dyes contain metallic salts that should not be
mix these chemicals. Therefore, if you are not sure, what dye it has.
applied, we should not perform the perm.
B- If the client washes daily with saline water, we should not perform it.
C- If any smoothing treatment was done with or without formaldehyde, we should not perform it.

This step is called DIAGNOSTIC.

4- It is not carried out in case of:

The hair has:

Straightening
Decoloration
Products that contain metal salts

B-Indirect: The hair is rolled (the chosen roller is mounted) and then
saturate with the appropriate liquid (15 to 20 min)
C-Semi-Indirect: The hair is rolled (the chosen roller is mounted)
with a gentle liquid, then saturating after time (10 min) with the strong liquid.

For better operation, hair should be kept damp only with water.

Liquid time: According to the type of hair
Hair type: For all hair types. Especially for porous or very

If the hair is dry and porous, do not saturate the second phase.
Upon applying the permanent wave solution (reducer), it begins to change the
structure of the hair once it comes into contact with the hair. Initially only

After this time, the hair is rinsed with plenty of water to remove the

8- Saturation: The saturation phase occurs with the application of the liquid

C- Taking care that the cut we are going to make is not
too short. Since the hair tends to lift with the process.

11- The precautions we must take before making the cut for the
permanent sound:
A- Hair type
B- Volume and shape that we want to give
C- Movement
What a fall
E- Texture
F- Size of curls we are going to use
G- Keep in mind that when hair is permanently curled, the waves
they make it look shorter, therefore, we should not cut from
more.
 Approximately, the total completion time is between one hour, hour
and media. What takes us the most time is the assembly of the design, the placement

Control time: Varies depending on hair type, texture: between 10 and 15, 15 and

groups.

15- It is advisable to do a dye after the perm process, since
that the dye oxidizes due to the chemicals in the perm solution and the
neutralizer.
16- After the curling process, we must rinse with warm water, with
the rollers in place and apply pressure with the towel for a few minutes,
next we apply the neutralizing liquid to all the curlers, working
quickly.
Do not leave wet, only damp, because the neutralized will be damp and not
will act.
Let it act for 5 minutes and neutralize again without the rollers, unrolling in shape.

17- Neutralizer:
It is the application of a neutralizing product (oxidizing) responsible for reconstructing the
desulfurated bridges of keratin, the hair molecule. Permanently fix
the modification of the change in the hair structure and restoring the pH to the hair.
18- Precautions to take:
First: we must conduct a prior diagnosis to know which product we should
use.
If we have doubts, it is advisable to conduct a strand test.
During: Follow the design pattern that we establish from the beginning, according to the
cut that we must make.
We must use it with caution, so that we do not spill product on the leather.

Keep checking that the curlers are placed correctly.
For the work to have good durability, we must carry out the process well.
