Hair styling, straightening and waving Flashcards
HAIR STYLING AIDS (HAIR FIXATIVES)
Two types:
- Polymer-based products
- Emollient-based products
- Help smooth out frizz and increase hair shine by aligning fibers and reducing friction
- No stiffening unlike polymer
Emollient-based products
Improve hair volume and height by increasing hair strand stiffness and hair fiber interactions
Polymer-based products
Examples:
- Hair spray
- Styling gel
- Mousse
- Liquid setting products
Polymer-based products
Examples:
- Hair cream
- Wax
- Pomade
- Oil spray
Emollient-based products
Alter the natural configuration of hair fibers and modify hair’s natural straightness/curliness
HAIR WAVING AND STRAIGHTENING PRODUCTS
Make use of curling rods
Temporary waving
- Products applied in two separate
steps - There is chemical treatment
- Strong bonds: disulfide bonds (broken down during permanent waving process)
Permanent waving
Use flat irons
For temporary effect
- Products applied in two separate
steps - Break the disulfide bonds and
restructure them - the chemical treatment breaks
disulfide bonds and realigns them to the desired look
For permanent effect
- Non-flaky
- Non-tacky
- Rapid drying time
- Strong hold
QUALITY CHARACTERISTICS of Polymer-based products
- Non-greasy
- Does not make hair look oily and limp
- Aids in hair manageability
- Improves shine
QUALITY CHARACTERISTICS of Emollient-based products
Permanent styling products can change the appearance
of human hair and are considered as OTC drugs in the US (t or f)
F; Hair styling is always considered a cosmetic, regardless of whether it is temporary or permanent
-These products do not change the function of hair cells, since these are dead cells

Sprayable Oils and Silicones (Oil Sheen Sprays)
Hair Creams
- Applied to dry hair as the final step of styling the hair
Hair Sprays
Two types of hair sprays
aerosol hair sprays and non aerosol
- Most widely used by both consumers and hair stylists
- Released as fine particles that dry
quickly - Convenient
(POLYMER-BASED HAIR STYLING FORMULATIONS)
Aerosol hair sprays
- Dispersed through plastic container with pump head
- Forms bigger droplets that wet hair more rapidly
>Takes longer to dry
(POLYMER-BASED HAIR STYLING FORMULATIONS)
Non-aerosol hair sprays
- Applied to towel-dried hair rolled onto curling rollers
>Less common now - Coat the hair fibers and set them in a curled shape
- Less sticky than the sprays
(POLYMER-BASED HAIR STYLING FORMULATIONS)
Setting Lotion
- Aerosol and non-aerosol
- Add volume, improve texture, and control hair mass
(POLYMER-BASED HAIR STYLING FORMULATIONS)

STIFFNESS OF HAIR FIBERS
Bending Test
- Measures force required to bend or break the polymer film
- Stiffness is proportional to the viscosity of polymer solutions and total amount of polymer deposited on the hair (indicator of the
effectiveness of polymer based product) - Hair swatches used is synthetic hair
Bending Test
FIXATIVE TACKINESS
Tackiness Test
- Hair tresses are treated with hairspray or fixative and evaluated by panelists
- Measures time needed to indicate absence of tack on hair which is equivalent to the drying time of the polymer film
Tackiness Test
- Initial length of curls is recorded and wide-toothed comb is passed through tresses, then length of tress is recorded
Curl Snap Test
- Uses the texture analyzer
> Omega (Ω) shaped instrument - Measures stiffness and increase of stiffness after applying the hair spray, as well as tackiness and drying time
- All in one test (measures tackiness and drying time)
- Temperature and humidity effects may also be evaluated
DYNAMIC HAIR SPRAY ANALYSIS
- Curl retention test
- Initial length of curls is recorded, then these are placed in
a high-humidity environment - Length is recorded at predefined time intervals
- % curl retention is calculated
HUMIDITY RESISTANCE OF TREATED HAIR TRESSES
- Treated hair tresses are hung into supporting board and small-toothed comb is passed
- Panelists inspects the hair, comb, and area under support stand to evaluate _______
Flaking
- Designed to protect hair from heat damage and friction, and enhance hair flexibility to reform and hold shape
- Sprayed after blow-drying or before using curling iron
- Includes silicones, conditioning polymers, film-forming polymers, and protein
HEAT PROTECTION SPRAY
HEAT PROTECTION SPRAY available as:
- Water-based and
- Hydroalcoholic preparations
Since both hair and skin consists of keratin, they are equally susceptible to attack of thioglycolates. (t or f)
F; There are two types of keratin.
- The skin contains soft keratin, where there is less cysteine and fewer disulfide bonds.
- The hair has hard keratin, which has more cysteine and more disulfide bonds, thus more
susceptibility to thioglycolate
- With occlusive agent like petrolatum which is applied to the scalp and hairline prior to chemical treatment
- May contain NaOH at 3.5%
(HYDROXIDE-BASED STRAIGHTENERS (LYE STRAIGHTENERS))
Base products
Contain less NaOH, and require base application on hairline only
(HYDROXIDE-BASED STRAIGHTENERS (LYE STRAIGHTENERS))
No-base products
- Contain alternative hydroxides like guanidine hydroxides made by combining calcium hydroxide with guanidine carbonate
- Less irritating
- Does not requires base application
(HYDROXIDE-BASED STRAIGHTENERS (LYE STRAIGHTENERS))
No-lye relaxers
Neutralizer resets the pH, minimize hair shaft swelling,
and complete relaxing treatment
(t or f)
T
Act in same was as thioglycolate-based hair perming products, except hair is not washed
prior to treatment
(REDUCING AGENT-BASED STRAIGHTENERS)
Thioglycolate-based straighteners
- Have pH around 7 and are milder to skin & hair
- Does not requires oxidant, but employ neutralizing solution containing sodium carbonate or bicarbonate
Sulfite-based products
- Contains formaldehyde as main active ingredient
- Keratin-based straightening solution is applied followed by high-temperature (150 to 200
oC) flat iron, then hair is rinsed and conditioned - Use is associated with severe adverse effects
