Services
1. services give you the ability to permanently change the hair's
natural wave and curl pattern.: Chemical Hair Texture
2. services can be used to curl straight hair, straighten overly curly
hair, or soften tightly coiled hair.: Texture
3. services are among the most lucrative and repetitive services in the
salon.: Chemical
4. are hair services that cause a chemical change within the hair's
natural wave and curl pattern.: Chemical Texture Services
5. Name 3 types of texturizing services.: Permanent Waving, Relaxing,
Curl Re-forming
6. happens when you add wave or curl to the hair.: Permanent Waving
7. happens when you remove curl or waves and leave the hair smooth
and straight.: Relaxing
8. are soft curl permanents that loosen overly curly hair and
changing tightly curly or coiled hair into loose curls or waves.: Curl Re-
forming
9. All chemical texture procedures involve changing the structure of the
hair.: Chemically & Physically
10.Name 3 structures of the hair shaft.: Cuticle, Cortex, Medulla
11. is the exterior layer of the hair that protects the hair from damage.: -
Cuticle
12. is the middle layer of the hair and is responsible for the
incredible strength and elasticity of the hair.: Cortex
13.Breaking of the cortex makes it possible to change the natural
wave pattern of the hair.: Side Bonds
14. is the innermost layer of the hair and does not play a role in
chemical texture services.: Medulla
15.The medulla maybe missing in hair type.: Fine
16.The medulla is also know as the or core.: Pith
17.pH stands for .: Potential Hydrogen
18.pH measures the acidity and alkalinity of a substance by measuring
the quantity of it contains.: Hydrogen Ions
19.The pH scale ranges from .: 0-14
20.On the pH scale is considered neutral.: 7
21.On the pH scale is considered alkaline.: Above 7
22.On the pH scale is considered acidic.: Below 7
23.The natural pH of hair and skin is between .: 4.5-5.5
24.Chemical solutions raise the pH of the hair to an state.: Alkaline
25.Raising the pH of hair opens the cuticle layer of the hair and allows

the solution to reach the cortex layer, where occurs.: Restructuring

, Milady Chapter 20 - Chemical Texture
Services
26.Coarse, resistant hair with a strong, compact cuticle layer requires a
chemical solution.: Highly Alkaline
27. Porous,
damaged or chemically treated hair requires an solution.: -
Acidic
28. are compounds that are made up of carbon, oxygen, hydrogen,
nitro- gen and sulfur.: Amino Acids
29. also known as end bonds are chemical bonds that join amino acids
together, end to end in long chains to form a polypeptide chain.: Peptide
Bonds
30. are long chains of amino acids joined together by peptide bonds.: -
Polypeptide chains
31. are long, coiled, polypeptide chains.: Keratin proteins
32. are disulfide, salt and hydrogen bonds that cross link
polypeptide chains together.: Side Bonds
33.Name 3 types of side bonds: Disulfide, Salt, Hydrogen
34. are strong chemical side bonds formed with the sulfur atoms in
two adjacent protein chains are joined together.: Disulfide bond
35.Disulfide bonds are not affected by .: Water
36. are weak physical side bonds that are the result of an attraction
between negative and positive electrical charges called ionic bonds.:
Salt bonds
37.Salt bonds are broken by the change in .: pH
38. are weak physical side bonds that are also the result of an
attraction between opposite electrical changes.: Hydrogen bonds
39.Hydrogen bonds can be broken by .: Water or heat
40. is a 2 step process where by the hair undergoes a physical
change caused by wrapping the hair on perm rods.: Permanent Waving
41.Hair then undergoes a chemical change caused by the application
of permanent waving solution and .: Neutralizer
42. solutions soften and swell the hair and they open the cuticle,
permit- ting the solution to penetrate into the cortex.: Alkaline permanent
waving
43.Once in the cortex, the waving solution breaks the disulfide bonds
through a chemical reaction called .: Reduction
44.In permanent waving reduction happens due to the .: Addition of
hydro- gen
45.Name 4 steps of the chemical process of permanent waving.:
Disulfide bonds joins the sulfur atoms of 2 adjacent polypeptide
