Tension-Causing Techniques and Required Approved Course of Study
Domain 3 tests tension control and the approved course of study. Tension-causing techniques pull on the follicle and scalp; repeated or excessive tension can cause traction alopecia, folliculitis, breakage, and permanent hairline loss.
High-risk techniques
Tight braids, cornrows, twists, locks, weaves, heavy extensions, tight ponytails, and repeated styling in the same direction. Risk rises with small sections, heavy hair additions, long wear times, and client pain.
Prevention standard
Consult and screen for scalp tenderness, thinning, breakage, and prior styles. Section appropriately, distribute weight, avoid pain, and check tension during service. Educate the client to return if soreness, bumps, or hairline thinning occurs. Document findings and referrals.
Required course of study
New York requires an approved natural hair styling course of 300 hours before examination. The curriculum must cover sanitation, anatomy and scalp/hair science, law and scope, practical styling, client consultation, and tension-causing techniques. Hours from an unapproved school do not qualify.
Worked example
A client wants “as tight as possible” cornrows. Reasoning: the request conflicts with the tension standard. The stylist uses larger sections, reduces extension weight, performs tension checks, and tells the client to report pain. The stylist documents the adjustment. If the scalp already shows thinning, the stylist declines the tight style and refers for evaluation.
Traps
“No pain, no gain”; ignoring early traction alopecia; overloading extensions; and assuming any 300 hours count if the school is not approved.
