Considerations
• Hair type
– Dry, oily, normal, chemically treated
• Hair condition
– Over-processed; chemically treated; damaged
by harsh products, improper care, or
exposure to the elements
• Home maintenance
– Inappropriate products used at home can
diminish the quality service you have provided
The pH scale
• Potential hydrogen – the amount of
hydrogen in a solution is measured on a
logarithmic scale ranging from 0-14
• 0 1 2 3 4 5 6 7 8 9 10 11 12
13 14
•
pH scale
• Acid
– 0 – 6.9 pH
• Neutral
– 7.0
• Alkaline
– 7.1 – 14
• The higher the alkalinity, the stronger & harsher
the shampoo which can leave the hair dry & brittle
History of pH balanced
shampoos
• 1960 Jheri Redding founded Redken, Jhirmack, Nexxus, &
Jheri Redding Products & marketed the first pH-balanced
shampoos. The litmus paper test was key in his marketing
strategies.
Chemistry of Water
Water is the universal solvent, meaning it is capable of
dissolving more substances than any other solvent
• Purification – fresh water from lakes & streams must
be purified for domestic use
– Sedimentation
• Treatment that causes matter to sink to the bottom
– Filtration
• Passing through a porous substance, such as filter paper or
charcoal. The process removes suspended clay, sand & organic
material
– Chlorine added
• Small amounts are added to kill bacteria
Chemistry of Water
• Purification
– Boiling
• 212* Fahrenheit or 100* Celsius, destroys microbes
– Distillation
• Process of heating water so it becomes a vapor, then condensing
the vapor so that it collects as a liquid. This process is used
frequently in the manufacture of cosmetics
• Soft water
– Rain water or chemically softened water. It contains small amounts of
minerals & allows soap & shampoo to lather freely
• Hard water
– Contains minerals that lessen the ability of soap or shampoo to lather
readily. Can be softened by a chemical process
Summary
• Shampooing is a service for cleaning and
massaging the scalp
• First impression your client has of you as a
hairstylist
• pH scale determines acid or alkalinity of a
product
