NY Cosmetology study guide
NY Cosmetology · Work through your exam, one topic at a time.
A New York cosmetology license authorizes you to provide service to the hair, head, face, neck, or scalp of a human being - a scope that reaches from shampooing, cutting, and styling to shaving, trimming, and beard work, the application of tonics, oils, and powders, and chemical services that dye, straighten, curl, or otherwise alter hair structure. The credential matters to anyone who wants to work behind the chair in a New York salon and to the owners who must staff with licensed practitioners. The NY Cosmetology study guide has 8 sections and about 2,136 words.
01Hair Care and Treatment: Shampooing, Conditioning, and Scalp Care
Every shampoo starts with a hair-and-scalp analysis: texture (fine, medium, coarse), density, porosity (how readily hair takes in moisture), elasticity (wet hair stretched should return, not snap), and scalp condition (normal, oily, dry, flaking). Porosity and elasticity tell you whether chemical services are safe later; the scalp tells you which shampoo fits now.
299 words, about 1 min02Hair Cutting and Shaping
Four ideas control every haircut: sectioning (clean, even partings), distribution (where hair is held relative to its natural fall), elevation or projection angle, and tension. Elevation is measured from the head: 0 degrees is blunt and one-length, 45 degrees is graduated, 90 degrees is uniform layers, 180 degrees is long layers.

Blow-drying builds volume or smoothness depending on tension and airflow: direct air down the shaft for smooth, against the natural fall for lift. Rollers and pin curls use three parts: base, stem, and curl.

Every chemical service starts with a consultation and hair analysis. Color and relaxers call for a patch test 24-48 hours ahead, and a strand test whenever the formula or timing is uncertain.

Cleanse and analyze the skin for type (normal, dry, oily, combination), condition (dehydration, sensitivity, aging, acne), and Fitzpatrick phototype to judge treatment caution. Contraindications include contagious or inflamed conditions, open lesions, recent waxing or peels, and some medications.

Nail plate, nail bed, matrix (where the plate is produced), lunula (visible matrix), cuticle (dead tissue on the plate), eponychium (living skin at the base), hyponychium (under the free edge), free edge, and sidewalls. Matrix damage shows up as a growth deformity.
