Procedure
1. Measure and cut the hair
into four 12 inch segments
and label the strands 1-3 with
color coordinating thread.
Keep one strand of hair
separate for the constant.
2. Take notes on which color
of thread is dedicated to
which shampoo for the
experiment.
3. Dye the hair according to
the instructions on the box.
Step Three.

Procedure
4. Let the hair air dry.
5. Mix one cup water
and 1 tablespoon of
baking soda in the
plastic bottle. Shake
well. This is your organic
shampoo.
6. Measure .25 mL of
each shampoo and put
in different cups.
7. Measure the
temperature of each
shampoo and record on
data sheet.
8. Measure .25 mL of
each conditioner and
place in cups.
9. Measure the temp of

shampoos for one
minute
12. Rinse strands until all
signs of shampoo are
gone.
13. Condition strands
with coordinating
conditioners and let sit

What Did We See?
VO5:
o Hair was lost in the sink
o Loss of color
JOICO:
o Very sudsy
o Loss of hair
o Loss of color
o Lost the most color
Organic:
o Loss of hair in sink
o Softer during wash
o No suds at all
o Dried faster than the others
The Results Are In
We Have Concluded
o The
hair washed with the organic shampoo
lost the least amount of color.
o The
hair washed with the VO5 lost the most
amount of color.
o Why
did this happen?
Dye or Die?
o The color of the cortex is your
natural hair color
o The cuticle is the outer layer, and is
clear.
o Hair turns gray when it no longer
produces a cortex
o We used a direct dye on our hair
o Direct dye stains the cuticle
masking the color of the
cortex.
o If the hair is damaged the direct
dye may get into the exposed
cortex making the dye permanent
Surfactants
o
o
“Surface active agent”
o
Lowers surface tension
o
Compound
Why does it do what it does?
o
Both hydrophobic (tail) and hydrophilic
(head)
o
Oil and grease contain skin, dirt,
and grease particles
o
Rinse takes away hydrophilic head.
What is pH?
o
The potential of hydrogen
o
pH from 1-6 is considered an acid
o
pH levels of 7 are considered a neutral
o
pH levels of 8-12 are considered a base
pH Levels in Shampoos
o
“No Poo” – pH of 8, basic.
o
VO5 & Joico – pH 4, acidic.
o
Water – pH 7, neutral
o
Hair Dye – pH 9
o
Hair
o
Sebum, pH 5.5
o
Shaft, pH 3.67
o
Acids harden and contract the hair, alkalis expand and soften the hair
What is in shampoo?
oWe
already told you.
oAre
they beneficial?
People chemically perm and
relax their hair.

What Did We Do?
1. Measure and cut the hair
into four 12 inch segments
and label the strands 1-3
with color coordinating
thread. Keep one strand of
hair separate for the
constant.
2. Take notes on which color

which shampoo for the
experiment.
3. Dye the hair according to
the instructions on the box.
4. Allow hair to air dry
5. Pre wash all of the hair
with alternate action
shampoo to help prepare
hair for chemical (perm)
solution.
6.Test run a perm rolled
piece of hair with perm
solution to make sure that
hair is able to be treated
without damaging effects.
7. If damage does not
occur, roll each single strand
of hair around a purple perm
rod.
8. Drip (step 1) perm solution
around each rolled perm
rod.
9. Allow perm rods to sit with
lotion wave solution on for 20

What Did We See?
o
Immediate color loss occurred
o
Hair became brittle
o
Breakage at the roots
o
Ends of hair became ratty and damaged
o
Pink lost most color/most damaged appearance
o
Blue was the softest
o
Purple held the tightest curls/most bouncy
We Conclude
o The hair washed with
the Joico shampoo and
conditioner yielded
more curls.
o The hair washed with
the VO5 was the worst.
Permed hair
o
Chemical hair treatments are highly effective due to the potency of the
chemicals used to create the change.
o
Process of perming hair…
o
Is it healthy?
Did You Know?
o
Karl Ludwig Nessler
o
He used WHAT?
o
How long would you
wait for curly hair?
o
How hot is too hot?
How Does a Perm Work?
o
We used an alkaline solution for our perm.
o
What is an alkaline solution?
o
- A solution containing alkali is considered alkaline.
o
- What is Alkali? – A base that dissolves in water
o
- A solution with a pH of 8 or more
o
- If the solution is a pH of 7 it is neutral
o
Integrated Chemistry Today says an alkaline solution will have a slippery feel
o
Alkaline solutions are used to dissolve fats, grease, oils, and even proteins
o
Alkaline perms have a pH of 9.5.
How Does A Perm Work?
o A high pH level, or alkaline, solution opens the cuticle in the
hair.
o The perm solution is then able to be directly applied to the
cortex region of the hair.
o The disulphide bonds of the hair shaft are chemically broken
and then reformed into the new shape.
Why did said shampoo work best?
oJoico
Endure Color Care
Shampoo wins!
oWhy
though?
Perming…
Question Three
Which shampoo yields the most
elasticity in the chemically
treated hair?
Our Claim
We believe the salon formula
shampoo and conditioner,
JOICO, will allow more elasticity in
the hair.
Elasti-what?

oWhy
oDo
is elasticity?
is it important?
I have that?

What Did We Do?

the constant.
2. Take notes on
which color is
dedicated to which
shampoo for the
experiment.
3. Dye the hair
according to the
instructions on the
box.
4. Let the hair air dry.
5. Mix 1 cup of water
and 1 tablespoon of
baking soda in the
plastic bottle. Shake
well. This is the
organic shampoo.
Mix 1 cup of water
and 2 tablespoons of
apple cider vinegar
to the second bottle.
Shake well. This is the
organic conditioner.
6. Measure ¼ tsp. of
each shampoo and
put in different cups
and record on data
sheet
7. Measure the
temperature of each
shampoo and record
on data sheet
8. Measure ¼ tsp. of
each conditioner
and put in different
cups and record on
data sheet
9. Measure the
temperature of each
conditioner and
record on data sheet
10. Measure the temp
of the water and
record on data
11. Work strands into
a lather for one
minute with assigned
shampoos.
12. Rinse strand one
until all signs of
shampoo are gone
13. Condition strands with
assigned conditioners and
let sit for 1 minute
14. Rinse strands until all signs
of conditioner are gone.
15. Blot dry hair with paper
towels.
16. Repeat steps 6-14 three
times.
17. After third round of
washing, remove a single
strand of hair from each of
the twelve sections.
18. Measure each strand of
hair and cut accordingly to
make sure that every strand
begins with an equal length
as the rest of the strands of
hair.
19. Once equal length is
acquired, hold each end of
the strand of hair.
20. Begin pulling to test the
elasticity of each strand of
hair.
22. Record all data of
elasticity.
23. Repeat steps 18-22 eight
times (three times per
shampoo type which
contains three strands of hair
for each).
24. Compare differences in
elasticity between the three
types of shampoo to
evaluate which shampoo
gives the hair the best
flexibility.
21. Once hair breaks into two
pieces, measure each piece
and add their measurements
together to find the length of
elasticity.

next?
Words of Wisdom
o
Hair and skin are much alike!
o
Healthy eating habits…
o
Over processing…
What causes it? How to restore and maintain healthy hair?
o
Fried strands…
What causes it? Helpful tips and remedies?

Conclusion of Conclusions
o Who
o Will
“won”?
this change the way we
buy shampoo or treat our
hair?
Now What?
o
Would our conclusions ended differently had we used human hair on an
actual scalp instead of the natural hair extensions?
o
Would natural oils or different hair types have made a difference in our
experiments?
o
Is it possible to dye or perm our hair without the damaging effects?
