cutting hair ends with a slight increase or decrease in length.
or A stacking tehnique
◉ single-use. Answer: Disposable items cannot be used more than
once
◉ Decontamination methods 2. Answer: Cleaning and Steriling
◉ Humectants. Answer: Substances that absorb moisture or
promote the retention of moisture.
◉ hair root. Answer: The part of the hair located below the surface
of the epidermis.
◉ structure of the hair root. Answer: hair follicle hair bulb dermal
papilla arrector pilimuscle sebaceous glands
,◉ traveling guideline. Answer: Also known as movable guideline;
guideline that moves as the haircutting progresses, used often when
creating layers or graduation.

when the sulfur atoms in two adjacent protein chains are joined
together.
◉ Mild relaxer. Answer: best for fine , color treated, or damaged hair
◉ surfactants. Answer: the second ingredient that most shampoos
have in common

◉ Density. Answer: measure the number of individual hair strands
on one square inch of scalp
◉ hair porosity. Answer: The ability of the hair to absorb moisture
