KY Cosmetology study plan

Label a blank diagram of the skin's layers and appendages, then state one barrier or sensory function for each layer from memory.

Trace the hair growth cycle (anagen, catagen, telogen) and match each phase to what a stylist can and cannot do to the hair during it.

Explain the difference between a coiled, wavy, and straight hair cross-section and predict how each shape affects elasticity and styling tension.

Define pH on a 0-14 scale and describe what an alkaline or acidic product does to the hair cuticle and skin's acid mantle.

Distinguish bacteria, viruses, fungi, and parasites by giving one hair, skin, or nail condition caused by each.

Differentiate local infection, general infection, and contagious versus noncontagious conditions using textbook definitions.

Identify the nail's matrix, bed, plate, lunula, and cuticle on a diagram and state the function of each.

Describe the composition of hair (keratin, cortex, medulla, cuticle) and explain how chemical services alter the cortex.

Demonstrate correct draping for a shampoo, a haircut, and a chemical service, naming each cape and towel used and why.

Perform a scalp and hair analysis and select a shampoo and conditioner based on porosity, density, and scalp condition.

Execute the four basic haircut sections and identify the lines (horizontal, vertical, diagonal) used for a blunt, graduated, and layered cut.

Explain the difference between elevation, projection, and overdirection and how each changes a finished cut.

Cut a one-length, a graduated, and a layered mannequin haircut, checking balance and sectioning at each step.

Explain the law of color (primary, secondary, tertiary) and predict the result of mixing two given colors.

Describe how hydrogen peroxide volume (10, 20, 30, 40) affects lift and deposit and select the correct developer for a stated target level.

Identify the three phases of a permanent wave (wrapping, processing, neutralizing) and explain what each does to the disulfide bonds.

Perform a patch test, strand test, and porosity test and record the results on a service record card.

Compare the chemistry of a hydroxide relaxer and a thio relaxer, including which is used for a lye versus no-lye service.

Explain how a keratin smoothing treatment differs from a relaxer in terms of bond change and aftercare.

Apply a single-process retouch to a mannequin with correct sectioning, application order, and processing time.

Perform a skin analysis (oily, dry, combination, sensitive) and build a facial routine matched to each skin type.

List the steps of a basic facial in order and name the purpose of each product applied.

Explain the difference between depilatory, waxing, and threading and state one contraindication for each.

Identify nail disorders (onychorrhexis, onycholysis, paronychia, fungal infection) and state which require referral to a physician rather than service.

Demonstrate proper handwashing and explain the standard precautions that apply to every client.

Summarize Kentucky licensing requirements, scope of practice, and salon sanitation rules, including required postings and record keeping.

Apply a professional ethics scenario (client confidentiality, scope of practice, refusal of service) and justify the correct response.

Complete two full-length timed practice exams and review every missed question back to its source concept.

Re-drill weak areas flagged in weeks 1-7, focusing on the two domains with the lowest practice scores.

Recite the key safety and law points from memory without notes.

Build a final one-page review sheet of formulas, pH values, developer volumes, and Kentucky rules.
