- Slide 1
- Most Effective Types of Hair Dye and After-Care Treatments Caitlin Boback and Kyla Semones Cousino High School
- Slide 2
- Purpose To find the best types of hair dyes and treatments in order to limit the damage exerted on hair when chemically processed 2
- Slide 3
- Background Hair Structure 3
- Slide 4
- Treatments Hair dyes Ammonia-free Ammonia-based After-care treatments Coconut oil and egg yolk Store bought deep conditioner 4
- Slide 5
- How Hair Dye Works Ammonia (alkaline) swells the hair cuticle by raising the pH level In ammonia-free dye, monoethanolamine (MEA) is used 5
- Slide 6
- How Hair Dye Works Dye is mixed with hydrogen peroxide Molecules enter the cortex through raised cuticle Ammonia-free Ammonia 6
- Slide 7
- How Hair Dye Works Hydrogen peroxide breaks down Peroxide breaks the bonds of pre-existing color Oxygen bonds to and oxidizes the colorless molecules of the hair dye Oxidized molecules swell and become colored due to reaction 7
- Slide 8
- After-care Treatments Necessary after chemically processing hair Product bonds to the scales of the cuticle and neutralizes the pH level Water based products 8
- Slide 9
- Problem Statement Which types of hair dyes and reconditioning treatments are best for hair health? 9
- Slide 10
- Hypothesis Least damaging hair dye Ammonia-free Most effective treatment Coconut oil and egg yolk 10
- Slide 11
- Materials Force Sensor After-Care Treatments Hair Dyes 11
- Slide 12
- Procedure Collect and measure hair samples Dye hair samples with ammonia or ammonia-free hair dye Treat samples with a deep conditioner or an oil and egg yolk treatment Let dry overnight 12
- Slide 13
- Procedure Hair samples were split into groups Ammonia Ammonia free Untreated (control) 13
- Slide 14
- Procedure 14
- Slide 15
- Procedure 15 Max: 0.6706
- Slide 16
- Data Measured Tensile Strength (Newtons) Force Sensor Diameter of hair (mm) Caliper 16
- Slide 17
- Data Analysis Two-sample t-test Ammonia vs. Ammonia free Deep conditioner vs. Oil and egg on ammonia Deep conditioner vs. Oil and egg on ammonia-free 17
- Slide 18
- Data Analysis Assumptions Normal distributions Simple random samples Independent groups 18
- Slide 19
- Ammonia vs. Ammonia-Free 19
- Slide 20
- Ammonia vs. Ammonia-Free P-value = 0.000082 Null hypothesis rejected 20
- Slide 21
- Ammonia: Deep Conditioner vs. Oil 21
- Slide 22
- Ammonia: Deep Conditioner vs. Oil P-value = 0.0196 Null hypothesis rejected 22
- Slide 23
- Ammonia-Free: Deep Conditioner vs. Oil 23
- Slide 24
- Ammonia-Free: Deep Conditioner vs. Oil P-value = 0.5840 Fail to reject null hypothesis 24
- Slide 25
- Conclusion Least damaging hair dye Ammonia-free hair dye Most effective treatment Coconut oil and egg yolk Treatments were equally effective on ammonia free dyed hair 25
- Slide 26
- Conclusion Ammonia-free hair dye does not open the cuticle as much as ammonia This allows less protein and moisture loss when compared Ammonia-free hair dye does not work as well, but causes less damage 26
- Slide 27
- Conclusion The main ingredient in commercial products is water Coconut oil is rich in lauric acid High affinity for proteins Low molecular weight allows for easy access into cortex Egg yolk easily bonds to cuticle scales and seals them 27
