Practical Manicuring Skills and Technique
This domain tests the hands-on sequence and product control that a practical examiner watches: correct anatomy, safe filing, cuticle care, polish application, acrylic and gel application, and pedicure technique. Questions often ask what caused a service failure or which step comes next.
Nail anatomy you must know
The matrix produces the nail plate; the lunula is the visible portion of the matrix. The cuticle is dead tissue on the plate, while the eponychium is the living fold at the base. The hyponychium seals the plate to the fingertip under the free edge, and the nail bed lies beneath the plate. Fingernails grow roughly 3 mm per month; toenails grow more slowly.
Filing and shaping
Match the shape to the client: square, squoval, round, oval, almond, stiletto, or coffin. Use 180-grit or finer on natural nails, file in one direction from side to center, and hold the file at about 45 degrees under the free edge. Sawing back and forth and filing deep into the corners thin the plate and cause splitting.
Manicure sequence
Consult and check for contraindications; wash hands; remove old polish; shape; soak; push cuticle with a wooden or plastic pusher; nip only a hangnail, never living tissue; massage; dehydrate the plate; apply base coat, two thin color coats, and top coat; dry.
Artificial nails
Prep is the determinant of retention: remove shine, dehydrate, prime only if the system requires it, and keep product off skin. For acrylic, use a medium-wet bead, thin at the cuticle, with the apex at the stress zone. For gel, apply thin coats and cure fully. Product touching skin causes lifting and can sensitize the client.
Pedicure
Use warm water and soak about 5–10 minutes with a disposable liner. Exfoliate, use a callus file on damp skin, and never use a blade. Massage, then polish. Diabetic clients need physician clearance and no sharp tools.
Electric files
Choose the bit for the task, keep it moving, use light pressure, and never use a coarse bit on the natural plate or near the cuticle.
Worked example
A client's acrylic lifts at the cuticle after one week. Lifting there usually means product touched the skin or the plate was not dehydrated. The fix is to remove the enhancement, re-prep the natural nail, and reapply with the bead placed slightly away from the cuticle. Adding more primer or filing the lifted edge does not solve the cause.
Traps that cost marks
- Overfiling the natural plate until it is thin and sensitive.
- Cutting the cuticle instead of pushing it.
- A bead that is too wet (bubbles, shrinkage) or too dry (brittle, lifting).
- Applying product to skin and triggering allergic reaction.
- Using a coarse electric bit on the natural nail.
