Is it possible that spending extra money on shampoo or conditioner will give you the hair of your
dreams? Have you ever wondered if changing your shampoo will get rid of bad hair days forever?
Shampoo and conditioner manufacturers want you to believe that this is true. Walk into any hair
salon, drug store, or grocery store in the country and there are seemingly endless choices of hair
products. This leaves consumers relying on advertising, trial and error, and information from hair
stylists to find the right shampoos and conditioners for them.

Task
The cosmetology department of a local Community College has hired your team has been hired
to research, from a scientific perspective, of pH in shampoos. Your team must provide the college
with:
A. a PowerPoint (or similar) presentation summarizing background research on the esthetic value
of using hair products with a certain pH

Process
1. Get together with your team. Divide up the tasks (such as research, experimental design,
collection of written submissions, presentation layout) fairly.
2. In your group conduct research on the following:

    • background   information about pH, the pH scale, and the pH of various household chemicals
          for comparison

    • the   pH of skin and the pH of various types of shampoo in comparison.

    • how   hair is affected by pH, what is the usual pH of shampoos, and why shampoos are
          created to have this pH

    •a   definition of the term “pH Balanced” and why shampoo manufacturers claim this to be a
          good thing (with examples)

The Resources section, below, provides some starting points for your research.

3. Prepare the PowerPoint presentation. Your team’s presentation should include the following:
(a) a title slide, including a purpose for the presentation, with the names of the team
(b) an introduction slide listing main manufacturer’s claims about hair care products
(c) several slides outlining pH, the pH scale, and the pH of skin, the pH of various types of
shampoo and the pH of various household chemicals in comparison.
(d) one slide for a conclusion to summarize the results of your research
