    1. Chapter 20 Chemical Texture Services A blast from the past

    2. pics.livejournal.com/.../pic/0003cc97/s320x240 www.scott.k12.va.us/rita/51757_2.JPG www.scott.k12.va.us/rita/51757_2.JPG

    3. Chemical texture services gives the ability to permanently change the hair’s natural wave pattern *offers variety of styling options ~used to curl straight hair ~straighten overly curly hair ~soften coarse, straight hair

    4. www.wisconsinhistory.org/.../archives/003095.asp trend911.com/wp-content/331.jpg all4women.co.za/files.php?file=HairCare1_1751... www.2009haircuts.info/.../2008/10/44.jpeg

    5. Add: • First perm recorded 4000 b.c. • First recorded perm given: • Wrapped over crudely made wooden rollers • Mixture of soil and water • Baked in sun • All day

    6. Texture services include: *Permanent waving *Relaxing *Curl Reforming (soft curl permanents) The Structure of Hair * involves chemically and physically changing the structure of hair

    7. The Cuticle *tough exterior layer *protects the hair from damage *chemicals must penetrate cuticle -into cortex www.hairfinder.com/hairquestions/hairporosity.jpg

    8. The Cortex *middle layer of the hair *responsible for strength and elasticity *breaking side bonds -changes the natural wave www.hairdressersus.com/micro/Image10b.jpg www.hairflatiron.org/.../damaged_hair_41220.gif

    9. Shows how prescription and recreational drugs get trapped in the cortex. Even an aspirin can affect the outcome of PW Blood supply Psychemedics.com

    10. The Medulla *innermost layer -called pith or core *does not play a role in texture services www.tardigrade.us/stfmel70.jpg

    11. Importance of pH in Texture Services *potential hydrogen *measures acidity and alkalinity *range from 0-14 7 is neutral below 7 is acidic Above 7 is alkaline 4.bp.blogspot.com/.../HellaciousHair222.jpg

    12. Chemical texturizers: • *raise the pH to soften and swell the hair • lifts the cuticle • allows solution to reach the cortex • *coarse, resistant hair requires a highly alkaline chemical solution www.pgbeautyscience.com/.../Damage%2016.jpg

    13. *porous, damaged, or chemically treated hair requires a less alkaline solution newsimg.bbc.co.uk/.../_44474174_hair18_416.jpg

    14. Basic Building Blocks of Hair Amino acids: *compound of carbon, oxygen, hydrogen, and nitrogen Add: 18 amino acids www.protocolsupplements.com/Sports-Performanc...

    15. Peptide bonds (end bonds) *link amino acids together *form polypeptide chain Polypeptide chains *long chains of amino acids web.virginia.edu/.../Images/8883n05_02.jpg images.stanzapub.com/readers/2008/09/28/1_6.png

    16. Keratin proteins • *long coiled polypeptide chains • Side bonds • *disulfide, salt, and hydrogen bonds www.foundationz.co.uk/.../hair_bonds.gif

    17. Keratin protein • *long chains of amino acids linked together end to end • Chemical bonds linking amino acids together • *peptide bonds • *end bonds • Chains of amino acids are called • polypeptides www.codefun.com/Images/Genetic/tRNA/image004.jpg

    18. Side Bonds • Cortex is made up of millions of polypeptide chains • *elasticity and strength • ~Disulfide bonds • ~Salt bonds • ~Hydrogen bonds

    19. Altering these side bonds makes: • ~wet setting • ~thermal styling • ~permanent waving • ~soft curl permanents • ~chemical hair relaxing possible farm2.static.flickr.com/1137/565739214_26d62e... www.caribehair.com/geovannaperm1.jpg

    20. Disulfide Bonds *strong chemical side bond *only broken by chemicals -not heat or water *chemical and physical changes -make PW, curl re-forming, and relaxing possible

    21. http://www.madsci.org/posts/archives/1998-05/892764277.Ch.r.htmlhttp://www.madsci.org/posts/archives/1998-05/892764277.Ch.r.html *strongest of three *accounts for one-third of hair’s overall strength

    22. Add: Disulfide bonds add strength to the keratin protein Disulfide bonds must be broken down during the perming process

    23. Salt Bonds *weak physical side bonds *easily broken by changes in pH *re-form when the pH returns to normal *accounts for one-third of hair’s overall strength www.pgbeautyscience.com/.../twoh/v3/Pump-3.jpg

    24. Hydrogen Bonds *weak side bonds *easily broken by water or heat wet setting/thermal styling *re-form as hair dries or cools *accounts for one-third of hair’s overall strength

    25. FYI: Wet set-physical change *breaking bonds *wetting hair/rolling on rollers *re-forms when hair is dry www.pgbeautyscience.com/.../twoh/v3/Perm-6.jpg

    26. Not in Book: Do not add, just listen The Client Consultation *most important part *first: -determine exactly what the client expects -what is possible *nothing will compensate for a lack of communication

    27. Ask open-ended questions • -find out what results are expected • What type of coloring product is used • -metallic salts/not on permed hair http://www.helpusendhunger.org/perms411dosanddonts/

    28. Look at pictures • -desired style • Previous texture services • -likes • -dislikes • Currently styles his/her hair • -discuss any changes resulting from the texture service 1.bp.blogspot.com/.../s400/hair+stylist.jpg

    29. Determine finished hairstyle • -haircut • -degree of curl or relaxing • Evaluate • -condition • -texture • -wave pattern • Fill out record card www.totalcosmetology.com/Images/barbers.jpg

    30. Results of spiral conventional perm with white rods z.about.com/d/womenshair/1/0/-/0/-/-/IMG_3058.JPG z.about.com/.../1/0/R/-/-/-/permafter.JPG www.wellpromo.com/upload/upimg23/Spiral-Perm-...

    31. Permanent Waving *two step process 1. Physical change -wrapping 2. Chemical change -PW solution -neutralizer media3.washingtonpost.com/wp-dyn/content/phot... cdn-write.demandstudios.com/.../80/5/20585.jpeg

    32. The Perm Wrap • Wet set versus PW • -difference: PW breaks the disulfide bonds • Size, shape, and type of curl = • size, shape, and type of rod • End of story!!!!!

    33. The correct perm rod and wrapping method=successful PW • ***selection of solution • ***What you wrap is what you get • Q. Without a perm tool, can I achieve a curl in the hair if the PW solution is applied to just the natural hair? Hair wrapped on a tongue depressor Q. What curl pattern can we expect to achieve ?

    34. Types of Rods • Concave rods • smaller diameter in the center • larger diameter on the ends • tighter curl in center • (I feel these follow the shape of the head better) stylors.com

    35. Straight rods *equal entire length *uniform curl *short rods -small awkward sections Hairfinder.com

    36. Add: • Selection of rod size • Amount of curl desired • Physical characteristics of the hair • -length • -texture • -elasticity

    37. Other Perm Tools • Soft bender rods • *12” long • *uniform diameter • *bent into almost any shape www.metroasis.com/suepermx.jpg Toolboxes.flexiblelearning.net

    38. Getsomehairapy.wordpress.com Beautystore.com Toolboxes.flexiblelearning.net

    39. Loop rod or Circle rod *12” long *uniform curl ***spiral ***extremely long hair Advanceddesigner.com Hairfinder.com

    40. Today: • Many perms are performed with • Large rollers • Rag rollers • Other tools to achieve large, loose curls • *large tools for root perms • *create lift and volume without curls

    41. Add: • Pre-perm analysis determines: • Is the hair in good condition • 2. Which perm product should be used • 3. Which perm wrapping technique and rod/parting sizes to use

    42. End Papers * end wraps *absorbent papers used to control the ends of the hair (protects) *extends beyond ends of hair -fishhooks (demo) *ends smooth and straight (covered) -fried ends

    43. Techniques: Double flat wrap *use while in school *most control over ends *evenly distributed Single flat wrap *does not protect ends *use only as a third paper Demo each

    44. Bookend wrap -one paper folded over -use with short rods/short lengths -avoid bunching ends -keep hair in center

    45. Sectioning a Perm *sectioning into panels -size, shape, and direction vary *then, divide into subsections/base sections *length and width of the rod being used Read “Here’s a Tip”

    46. *** Break the rule -11 perm rod PW Lasts about 2 months z.hubpages.com/u/1186366_f520.jpg colorperfectsalon.com/images/Weav.JPG

    47. Base Placement • Position of rod to its base • On base • -45 degrees angle beyond perpendicular • -greater volume • -my preference • -can mark or break the hair…use picks www.schillingdouglas.com/images/perm_new.jpg

    48. Half off base- -90 degree angle -minimizes tension ***minimizes crispness of curl Off base -45 degrees below center (perpendicular) -least volume (scalp area-no curl) en.ask-schwarzkopf.com/content/image_path/125... i.ehow.com/.../5052200/209825-main_Thumb.jpg

    49. Base Direction *horizontally, vertically, or diagonally *backward, forward, or to one side *wrapping with the natural direction of hair growth causes less stress/less breakage -against hair growth “band” or breakage

    50. FYI: Not on Test • Direction of Hair Growth • Streams, whorls, and cowlicks • base direction • wrapping pattern • ***wrapping the hair in the opposite direction will help client manage an area better for about 2 months
