Study Notes
Nail Disorders
- Corrugations: Characterized by horizontal wavy ridges on nails due to uneven growth caused by illness or injury.
- Furrows: Display vertical lines on the nail plate, resulting from nutritional issues, injury, or illness.
- Leuconchia: Presents as white spots on the nail, typically caused by an injury at the nail's base.
- Onychorrhexis: Refers to split or brittle nails resulting from injury, poor filing habits, vitamin deficiencies, illness, or exposure to chemicals.
- Hang Nails: Occur due to dry cuticles and improper cuticle removal.
- Onychomycosis Unguium: A fungal nail infection that is highly contagious.
- Onychocryptosis: Known as ingrown nails, often resulting from excessive filing or wearing tight shoes.
- Verruca: Warts caused by infectious viruses.
- Onycholysis: Describes the separation of the nail from the nail bed without complete shedding.
Nail Shapes
- Basic nail shapes include squoval, round, oval, pointed, and square.
Hair Coloring Techniques
- Toner: Used on pre-lightened hair to achieve lighter, delicate shades.
- Conditioning Filler: A protein conditioner that equalizes porosity and fills gaps in hair.
- Color Filler: Replaces missing primary colors in hair.
- Oxidative Color: Includes demi-permanent and permanent hair colors.
- Non-Oxidative Color: Temporary and semi-permanent color changes with no lifting ability.
Lightening and Coloring Processes
- Double Process Blonde: Involves simultaneous decolorization and toning of hair.
- Melanin's Effect on Lightener Working Time: Higher melanin levels require longer processing time, while the scalp processes faster due to heat.
- Lift: Refers to lightening hair by breaking down melanin.
- Deposit: Technique that only adds color without lifting, due to the absence of ammonia or high alkalinity.
- Developer: An oxidizing agent, often H2O2, that aids in breaking down melanin for color lift.
Types of Hair Color
- Permanent Color: Lightens and deposits color simultaneously, contains more alkaline ingredients, and penetrates the cortex.
- Demi-Permanent Color: Deposits only, deepening or changing hair tone.
- Semi-Permanent Color: Non-oxidative, temporary color that stains the cuticle and fades with each shampoo.
Color Theory
- Primary Colors: Red, blue, yellow.
- Brown: An unequal mix of primary colors.
- Black: Formed by equal proportions of all primary colors.
- Warm Tones: Include red, orange, and yellow.
- Cool Tones: Comprise blue, green, and violet.
- Neutral Tones: A perfect balance of warm and cool tones.
- Eumelanin: Responsible for brown to black pigment.
- Pheomelanin: Provides red to yellow pigment.
Hair Texture Characteristics
- Coarse Texture: Largest diameter, highest melanin content, affecting processing time and lift.
- Medium Texture: Balanced melanin levels, typically presents no issues.
- Fine Texture: Smallest diameter, least melanin, more prone to damage and undesirable color results.
Permanent Wave Techniques
- Alkaline Wave: Known as cold waves, utilizes ammonium thioglycolate with a pH of 9.0-9.6; processes at room temperature.
- Acid Wave: Also called heat waves, requires added heat, with a pH of 7.8-8.2.
- Endothermic: Requires an external heat source for processing.
- Exothermic: Self-heating waves that generate their own heat during processing.
- Croguiqnole: Wrapping technique starting from the ends to the scalp, producing tighter curls on the ends.
- Spiral: Wrapping hair in a spiral direction along the rod's surface, not perpendicular to the rod.
Hair Placement Techniques
- On Base Placement: Hair is positioned at a 45-degree angle forward.
- 1/2 Off Base Placement: Hair is held 90 degrees straight up.
