MT Cosmetology study guide
MT Cosmetology · Work through your exam, one topic at a time.
The Montana cosmetology credential is a state-issued license that lets you legally perform hair, skin, and nail services for paying clients in Montana. It is for students finishing an approved cosmetology program and for out-of-state licensees seeking Montana licensure through endorsement. The MT Cosmetology study guide has 8 sections and about 2,549 words.
01Hair Care and Haircutting
The Hair Care and Haircutting domain tests whether you can analyze a client's hair, choose products that match that analysis, and execute a cut whose line, elevation, and distribution you can explain and defend. Four properties matter: texture (strand diameter), density (strands per square inch), porosity (how readily the cuticle absorbs and releases moisture) and elasticity (stretch-and-return).
338 words, about 2 min02Hair Coloring and Chemical Texture Services
This domain tests formulation logic: reading natural level and underlying pigment, choosing developer strength, predicting lift versus deposit, and controlling the reduction and re-bonding steps of texture services. Levels run 1 (black) to 10 (lightest blond).
317 words, about 2 min03Hairstyling and Finishing
This domain tests whether you can build a shape with heat or wet-setting tools, place volume where the design needs it, and finish a style that holds without looking heavy. Rough-dry to about 90 percent before picking up a thermal iron; ironing damp hair traps steam and can burn both hair and scalp.
332 words, about 2 min04Skin Care and Facial Services
This domain tests client screening, skin analysis, safe massage manipulations, and knowing when a service must stop and a client must be referred. Classify skin as normal, dry, oily, combination or sensitive, and note Fitzpatrick type because it predicts reactivity.
291 words, about 1 min05Nail Care and Manicuring
This domain tests implement care, filing technique, product application, and recognizing when a nail condition belongs to a physician rather than a manicurist. Metal implements are cleaned of debris, then fully immersed in an EPA-registered hospital-grade disinfectant for the label contact time.
316 words, about 2 min06Anatomy, Physiology, and Histology of Hair, Skin, and Nails
This domain tests structure and function: the layers of skin, the anatomy of the follicle, the nail unit, and the bones, muscles, nerves and vessels of the head and face that guide massage and service safety. Epidermis is the protective outer layer, with the basal layer producing new cells.
327 words, about 2 min07Sanitation, Disinfection, and Infection Control
This domain tests the vocabulary of infection control, the exact order of implement processing, and the habits that break the chain of transmission in a salon. Cleaning removes visible debris with soap and water.
299 words, about 1 min08Montana Cosmetology Law, Rules, and Professional Ethics
This domain tests how Montana regulates the industry: who makes the rules, what each license permits, and the ethical duties that accompany holding one. Always study the current statute and rule text; training hours and fees are revised and prep books go stale.
