9.2 Manicuring & Pedicuring Procedures and Equipment

Quick Answer: Professional manicuring and pedicuring combine technical grooming with rigorous infection control. Nails are shaped from the outside corner to center at a 45-degree angle into one of five basic silhouettes: square, squoval, round, oval, or pointed. A standard manicure follows a strict sequence: sanitization, polish removal, shaping, soaking, chemical cuticle softening, gentle eponychium pushing, trimming only dead hangnails, massage, dehydration, and a 4-coat polish application. Minnesota law strictly bans razor blades, credo blades, and metal graters for callus cutting. After every client, pedicure tubs are drained, scrubbed, rinsed, and run with an EPA-registered hospital-level disinfectant for the full label contact time (Minn. R. 2105.0375, subp. 12). For diabetic clients, practitioners must avoid sharp tools, use lukewarm water, and omit vigorous massage.

The Five Classic Nail Shapes

Proper nail shaping enhances the aesthetic appearance of the client's hands while preserving the structural integrity of the natural nail plate. The ideal shape is selected during consultation based on finger length, hand shape, nail bed width, and the client's occupation and lifestyle:

1. Square

• Contour: Completely straight across the free edge with sharp, crisp 90-degree lateral corners.
• Structural Strengths & Weaknesses: Provides tremendous lateral strength across broad nail beds. However, sharp square corners readily catch on fabrics and are susceptible to chipping and tearing if the nail plate is thin.
• Ideal Candidates: Clients with long, slender fingers and wide nail beds; individuals who prefer a modern, geometric look.

2. Squoval (Square-Oval)

• Contour: Straight across the free edge with gently rounded, softened outer corners.
• Structural Strengths & Weaknesses: The most durable and versatile natural nail shape. It combines the structural strength of a square silhouette with the wearability and snag-free comfort of an oval shape.
• Ideal Candidates: Highly recommended for clients with active lifestyles, typing-intensive occupations, or weak natural nails prone to edge breakage.

3. Round

• Contour: Slightly tapered along the sidewalls and softly curved to mirror the natural spherical contour of the fingertip. The free edge extends slightly beyond the distal pad.
• Structural Strengths & Weaknesses: Exceptionally sturdy, low maintenance, and resistant to chipping. Ideal for maintaining natural nail health.
• Ideal Candidates: Clients with short nail beds, active athletes, healthcare professionals, and male grooming clients.

4. Oval

• Contour: A classic, conservative silhouette where the lateral edges taper gracefully into an elongated, gentle curve extending well beyond the fingertip.
• Structural Strengths & Weaknesses: Creates an elegant aesthetic; however, tapering the sidewalls removes lateral structural support, making long natural oval nails vulnerable to edge fractures if subjected to heavy impact.
• Ideal Candidates: Clients with shorter, wider fingers seeking the visual illusion of slender, elongated hands.

5. Pointed (Stiletto)

• Contour: Tapers dramatically from the sidewalls to a sharp, centered point at the distal tip.
• Structural Strengths & Weaknesses: Structurally very weak on natural nails because the lateral stress walls are completely filed away. If subjected to lateral pressure, natural pointed nails fracture immediately into the nail bed. Best executed using sculpted acrylic or hard gel enhancements.
• Ideal Candidates: Clients seeking high-fashion, dramatic aesthetics with medium-to-long artificial nail extensions.

Professional Plain Manicure: Step-by-Step Workflow

A professional plain manicure follows a standardized ten-step workflow engineered to maximize client comfort, technical precision, and infection prevention:

1. Hygiene & Consultation: Wash and sanitize practitioner hands thoroughly with liquid antimicrobial soap. Assist the client in sanitizing their hands. Examine the client's hands, nails, and periungual tissues under adequate lighting, checking for active contraindications, open sores, or fungal/bacterial infections.
2. Polish Removal: Saturate a lint-free cotton pad with acetone or non-acetone polish remover. Press the pad firmly against the nail plate for 3 to 5 seconds to soften the lacquer. Stroke firmly from the proximal nail fold outward toward the free edge. Avoid rubbing back and forth across the skin to prevent smearing dissolved pigment into the eponychium.
3. Nail Shaping: Select a clean, disinfected abrasive board with a grit of 240 or higher for natural nails. Hold the board at a 45-degree angle beneath the free edge. File smoothly from the outside corner toward the center in one fluid motion. Repeat on the opposite side. NEVER saw back and forth like a carpenter's saw; sawing generates frictional heat, splits the keratin layers, and causes jagged edges and chronic delamination.
4. Fingerbowl Soak: Submerge the client's fingers in a sanitized fingerbowl filled with warm water and a mild antibacterial liquid hand soap. Soak for 3 to 5 minutes to soften dead cuticle cells and rehydrate periungual skin. (Avoid prolonged soaking, which over-hydrates the nail plate, causing premature polish chipping).
5. Cuticle Softening & Pusher Technique: Dry the hand thoroughly with a clean towel. Apply a small drop of chemical cuticle remover (potassium hydroxide or sodium hydroxide formulation) around the base of the nail plate. Hold a sanitized stainless-steel cuticle pusher at a 45-degree angle with the spoon side resting flat against the nail plate. Gently guide the dead cuticle tissue back off the nail plate. Never dig, gouge, or press down with the sharp corner of the pusher, which injures the delicate underlying matrix.
6. Cleaning & Hangnail Grooming: Wrap the beveled end of a clean wooden orangewood stick with a thin wisp of sterile cotton, saturate with antiseptic, and gently clean beneath the free edge of the nail plate, taking care not to rupture the hyponychium. Examine the sidewalls and eponychium for loose, dead hangnails. Using a sanitized, sharp cuticle nipper, carefully nip ONLY the loose, dead hanging skin tag. NEVER cut, trim, or nip the living eponychium or sidewalls!
7. Hand & Forearm Massage: Apply professional massage lotion or oil. Perform classical Swedish massage manipulations for 5 to 10 minutes: initiate with soothing effleurage gliding up the forearm to the elbow, proceed with petrissage kneading on the fleshy muscles of the arm and palm, incorporate circular friction around the wrist, and conclude with relaxing effleurage.
8. Nail Plate Dehydration: Polish will not adhere to an oily surface. Thoroughly cleanse and dehydrate the dorsal surface of each nail plate using a lint-free wipe saturated with 70%+ isopropyl alcohol or a specialized nail dehydrator. Ensure all traces of massage lotion, oil, and moisture are eliminated from the sidewalls and cuticle area.
9. Four-Coat Professional Polish Application:
   • Base Coat (1 coat): Apply one thin, even coat over the entire nail plate. The base coat adheres to the natural keratin, creates a tacky bonding surface, and prevents dark pigments from staining the porous nail plate yellow.
   • Color Polish (2 coats): Apply the first coat thinly down the center of the plate, then stroke each side. Cap the free edge to prevent premature tip wear. Apply a second thin coat to build color depth and full opacity.
   • Top Coat (1 coat): Apply one smooth coat of high-gloss top coat, capping the free edge. Top coats contain specialized plasticizers and nitrocellulose resins that impart brilliant shine, seal the pigment layers, and resist chipping.
10. Drying & Conditioning: Apply quick-dry drops or spray over each nail plate. Position the client under a nail dryer. Finish by lightly massaging a drop of nourishing cuticle oil into the living eponychium and sidewalls to restore cutaneous hydration.

Professional Pedicure Procedures & Technical Execution

A pedicure encompasses cosmetic care, nail shaping, callus smoothing, and relaxation of the feet and lower legs. Feet carry unique microbial flora and anatomical vulnerabilities requiring strict procedural execution:

Foot Soak & Consultation

Assist the client into the pedicure chair. Immerse the feet in a warm foot bath infused with an antiseptic foot soak solution for 5 to 10 minutes. While soaking, review the client consultation card, checking for medical conditions, diabetes, poor circulation, neuropathy, or active fungal infections (tinea pedis/athlete's foot).

Toenail Clipping & Shaping

Lift one foot, dry thoroughly (especially interdigital spaces between toes), and place on a sanitized footrest:

• Clipping Technique: Trim toenails straight across using heavy-duty toenail clippers or nippers. The length of the free edge should remain even with or slightly past the tip of the toe.
• Ingrown Prevention: NEVER round down into the lateral corners or dig deep into the sidewalls! Cutting down into the corners encourages the sharp edge of the growing nail plate to embed into the adjacent soft tissue, precipitating painful onychocryptosis (ingrown toenails) and secondary bacterial infections.
• Smoothing: Smooth the straight free edge with an abrasive foot file (180 to 240 grit), barely rounding the sharp distal corner points to prevent catching on socks.

Callus Reduction vs. Callus Removal: The Credo Blade Prohibition

Calluses are localized, thickened areas of the stratum corneum that develop naturally as a physiological defense mechanism against chronic friction and mechanical pressure on the weight-bearing surfaces of the foot (heels and balls of the feet):

• Authorized Callus Reduction: Cosmetologists are legally authorized to soften and gently reduce calluses. Apply a professional callus softener formulation containing urea, salicylic acid, or potassium hydroxide. Allow to penetrate for 3 to 5 minutes, then gently buff the thickened area with a disinfected metal or glass foot file or a new pumice stone (pumice is single-use in Minnesota). Smooth only until the surface is soft and supple; never remove the entire protective callus layer.
• Prohibited Callus Shaving Tools: Minn. Stat. 155A.355 and Minn. R. 2105.0377 prohibit credo blades and other razor-type callus shavers, rasps and graters; they may not even be present in a salon. Using razor blades to shave or slice calluses cuts into living dermal tissue, causes severe hemorrhaging, introduces deep bacterial pathogens, and constitutes the unauthorized practice of medicine.

Pedicure Tub Cleaning in Minnesota

Improperly cleaned pedicure tubs can spread bacteria such as rapidly growing Mycobacterium species and Pseudomonas, as well as fungi. Minnesota's procedure is in Minn. R. 2105.0375, subp. 12 (detailed in Section 2.5):

1. Immediately after each service: drain the water and remove visible debris.
2. Remove the filter screens, inlet jets, footplates, impeller assemblies and other removable parts and scrub them with a disinfected brush and detergent and water.
3. Scrub the basin with detergent and water, rinse and drain, then replace the parts.
4. Refill with clean water and an EPA-registered, hospital-level disinfectant mixed per the label. For an electrical tub, run the pump for the entire label contact time.
5. Drain, rinse with clean water, and wipe the faucet, handles and controls with a disinfectant wipe, keeping them wet for the contact time.

Liners are single-use. A salon that uses liners must use them in every tub, clean the basin with soap and water after each lined service, and perform the full procedure on every tub at the end of each business day. Tubs must stay clean and disinfected even when broken or out of service.

Foot and Lower Leg Massage

Foot massage uses the same manipulations as hand massage: effleurage strokes over the top and sole of the foot and up the lower leg, joint (relaxer) movements at the ankle, thumb friction across the sole, and gentle compression, finishing with effleurage. Avoid massage over varicose veins, swelling, bruises, open skin or areas of numbness, keep pressure light for elderly and diabetic clients, and stop if the client reports pain.

Special Clinical Precautions for High-Risk & Diabetic Clients

Clients diagnosed with diabetes mellitus or peripheral vascular disease represent a highly vulnerable clinical population requiring comprehensive pedicure service modifications. Cosmetologists must recognize the severe physiological hazards involved:

1. Diabetic Neuropathy

Diabetic nerve damage (peripheral neuropathy) blunts or completely eliminates sensory perception in the feet. A diabetic client cannot accurately perceive excessive water temperature, sharp pain from a tool nick, or chemical stinging from an aggressive acid peel. The practitioner cannot rely on the client's verbal feedback to detect danger.

2. Peripheral Artery Disease & Compromised Healing

Diabetes compromises microvascular blood circulation and suppresses immune response in the extremities. A microscopic skin puncture, tool scratch, or aggressive callus tear that would heal quickly on a healthy individual can develop into an ischemic non-healing diabetic ulcer, gangrene, systemic sepsis, or lead to surgical amputation of toes or the foot.

Required Service Modifications for Diabetic Clients

• Consultation Screening: Review the client's intake card carefully. Inquire gently if they have diabetes, take anticoagulant blood thinners, or experience numbness in their extremities.
• Water Temperature Control: Water must be lukewarm, never hot. Always test water temperature using a thermometer or on the sensitive inner surface of the practitioner's wrist before immersing the client's feet.
• Avoid Sharp Implements: Do not cut cuticles or work near the skin with sharp metal implements on a diabetic client. Gently push the cuticle with a towel or a cotton-wrapped wooden pusher, never nip living tissue, and recommend that toenail and foot problems be handled by a physician or podiatrist.
• No Aggressive Callus Filing: Never use aggressive coarse abrasive rasps or chemical callus peels. Apply gentle moisturizing foot balms and very lightly stroke with a fine-grit buffer to smooth roughness.
• Massage Modifications: Omit all vigorous, deep massage manipulations! Do not perform deep petrissage (kneading) or tapotement (percussion) on the legs or calves, which can dislodge underlying blood clots (deep vein thrombosis) or bruise fragile capillaries. Utilize only light, soothing, superficial effleurage strokes.
