QR Challenge: Colour and lighten hair

Created using the ClassTools QR Treasure Hunt Generator

Teacher Notes

A. Prior to the lesson:

1. Arrange students into groups. Each group needs at least ONE person who has a mobile device.

2. If their phone camera doesn't automatically detect and decode QR codes, ask students to

• Download a QR reader (e.g. I-Nigma | NeoReader | Kaywa) onto their mobile devices
• Bring these devices into the lesson.

3. Print out the QR codes.

4. Cut them out and place them around your class / school.

---

B. The lesson:

1. Give each group a clipboard and a piece of paper so they can write down the decoded questions and their answers to them.

2. Explain to the students that the codes are hidden around the school. Each team will get ONE point for each question they correctly decode and copy down onto their sheet, and a further TWO points if they can then provide the correct answer and write this down underneath the question.

3. Away they go! The winner is the first team to return with the most correct answers in the time available. This could be within a lesson, or during a lunchbreak, or even over several days!

Questions / Answers (teacher reference)

Question	Answer
1. Can cause choking, coughing, chest tightness/ problems, internal damage, scarring of the respiratory tract, asthma attack	Explain the dangers associated with inhalation of powder lighteners
2. Visual aid, international numbering system, depths 1 to 10, 1 = black, 10 = lightest blonde	Describe how the international colour chart is used to select colour
3. Tones – primary tone, secondary tone, 6 main tones (ash, gold, red, copper, mahogany, pearl)	Describe how the international colour chart is used to select colour
4. Temporary products – no skin test required, large molecules, coat cuticles, last one shampoo, do not lift, deposit colour (depth and tone	Describe how each of the colour products affect the hair structure
5. Semi-permanent products – no skin test required, contain nitro dyes, small molecules deposited under cuticle/ outer edge of cortex, last between 4-8 shampoos, direct colorant (no activator required), do not lift, deposit colour, depth and tone	Describe how each of the colour products affect the hair structure
6. Quasi-permanent products – require a skin test, contain nitro/para dyes, small molecules enter cortex, stain, not permanent, last 12-24 shampoos, do not lift, deposit colour (depth and tone), require activator/developer/hydrogen peroxide, mixing ratio generally 1:2	Describe how each of the colour products affect the hair structure
7. Permanent colour products – require skin test, contain para dye, small molecules enter cortex, swell and become trapped, permanent, can lighten up to 4 shades, darken, add/change/neutralise tone, cover 100% white hair, require activator/ developer/hydrogen peroxide, generally 1:1 mixing ratio	Describe how each of the colour products affect the hair structure
8. Lightening products (high lift tint) – skin test required, permanent, suitable for base 6 and above, lift and lighten hair 4-5 shades, add/change/neutralise tone, mix with activator/developer, generally 1:2 mixing ratio, kinder than bleaching products	Describe how each of the colour products affect the hair structure
9. 3% /10 vol – tone, darken, cover white hair	Explain the uses of hydrogen peroxide when colouring and lightening the hair
10. 6%/20vol – tone, darken, lighten 1 shade, cover white hair	Explain the uses of hydrogen peroxide when colouring and lightening the hair
11. 9%/30 vol – lighten 2-3 shades, tone/blend white hair	Explain the uses of hydrogen peroxide when colouring and lightening the hair
12. 12%/40vol – lighten 4 shades with tint, 4-5 shades with hi-lift tint, lighten up to 7 shades with bleaching products	Explain the uses of hydrogen peroxide when colouring and lightening the hair
13. The higher the strength of the hydrogen peroxide, the more- free oxygen is available and the more oxygen released into the hair the higher degree of lift that is achieved. When colour deposit only is required then a lower-strength hydrogen peroxide will suffice	State what‘percentage and volume strength hydrogen peroxide’means
14. Restoring the hair to its natural pH using conditioner: Stops oxidisation process (colouring/perming), prevents damage, returns hair to its natural state (slightly acidic), closes cuticles	State
15. Scalp irritation – remove immediately, seek medical advice	problem
16. Uneven result – spot colour area if condition allows	problem
17. Hair breakage – conditioning treatments, cut, use of aftercare products	problem
18. Product seepage – spot colour area with natural colour	problem
19. Colour fade – use a semi- or quasi permanent product	problem
20. Inadequate coverage on white hair – pre-soften hair, double base colour, mix base shade mixed with fashion shade	problem
21. Incorrect tone achieved – neutralise with corresponding tone	problem
22. Hair not light enough – product removed too soon, re-apply if conditions allow	problem
23. Important part of service, avoid technical language, maintain eye contact, suggest/ advise/recommend, provide information, Maintenance	advice
24. frequency of visit, regular services, minimise chemical treatments, correct use of electrical equipment, product use and demonstration	aftercare
25. State the factors that need to be considered when selecting colouring products	Clarify the condition of hair, previous chemical services and benefit to client, identify influencing factors, test hair, ensure compatibility with client’s lifestyle, review findings, what will work and what will not?, draw conclusions, create a plan.
26. Explain the importance of carrying out the necessary tests prior to, and during, the colour service and recording the results	Record card up-to-date and accurate, essential information, future reference, professional image, legal implications, all test results, skin sensitivities (reaction), allergies (latex, nut, plasters, perfume, oil), history of allergic reactions (positive reaction to skin test), incompatible products (metallic salts, previous chemical treatments), medication (prescription medication), medical condition (high blood pressure, pregnancy, radiotherapy, cancer).
