Nail Anatomy


Key Concepts

Understanding nail anatomy is foundational — exam questions often test whether you can identify structures by function, not just by name.


| Structure | Location | Primary Function |

|---|---|---|

| Nail Matrix | Base of nail, under skin | Produces nail plate cells; source of all growth |

| Nail Plate | Visible hard surface | Protective covering of the nail bed |

| Nail Bed | Underneath nail plate | Supports the nail plate |

| Eponychium (Cuticle) | Base of nail plate, overlapping lunula | Seals against pathogen entry |

| Hyponychium | Under the free edge | Protective seal between nail plate and fingertip |

| Lunula | Visible half-moon at nail base | Visible portion of the nail matrix |

| Free Edge | Tip of nail plate | Extends beyond the fingertip |


Key Terms

  • • Eponychium – The living skin at the base of the nail plate that overlaps the lunula; commonly referred to as the cuticle
  • • Hyponychium – The thickened skin layer beneath the free edge; protects against bacteria and fungi entering the nail bed
  • • Lunula – The whitish half-moon shape at the nail base; appears lighter because the thicker matrix tissue obscures underlying blood vessels
  • • Nail Matrix – The tissue responsible for nail growth; contains nerves, lymph vessels, and blood vessels
  • • Free Edge – The portion of the nail plate that extends past the fingertip

    • Growth Rates

  • • Fingernails: ~1/8 inch (3 mm) per month
  • • Toenails: ~1/16 inch per month (roughly half the rate of fingernails)

    • > ### ⚠️ Watch Out For

    > - The eponychium and cuticle are often used interchangeably, but technically the cuticle is the dead tissue that adheres to the nail plate, while the eponychium is the living tissue. Know both terms.

    > - The lunula is part of the matrix, not the nail bed — this distinction is commonly tested.

    > - Do not confuse the hyponychium (under the free edge) with the eponychium (at the base). Their locations and protective roles are different.

    Nail Disorders & Diseases


    Understanding the Difference: Disorder vs. Disease

  • • Nail Disorders – Abnormal conditions that may or may not be caused by infection; some allow cosmetology services
  • • Nail Diseases – Conditions caused by infection (bacterial, fungal, viral); cosmetologists must refuse service and refer to a physician

    • Common Nail Disorders


    | Condition | Description | Service Allowed? |

    |---|---|---|

    | Leukonychia | White spots or streaks caused by matrix injury | ✅ Yes — benign, grows out |

    | Beau's Lines | Horizontal ridges/depressions from disrupted matrix activity | ✅ Yes — unless infected |

    | Onychophagy | Nail biting; causes plate deformity and cuticle damage | ✅ Yes — unless infection present |

    | Onycholysis | Separation of nail plate from nail bed at the free edge | ❌ No — contraindication |


    Common Nail Diseases


    | Condition | Description | Service Allowed? |

    |---|---|---|

    | Onychomycosis | Fungal infection; yellowing, thickening, crumbling of nail plate | ❌ No — refer to physician |

    | Paronychia | Bacterial infection of the skin around the nail | ❌ No — refer to physician |


    Key Terms

  • • Leukonychia – White spots or streaks on the nail plate; benign and caused by minor matrix injury; grow out naturally
  • • Onychomycosis – Fungal nail infection; a mandatory refusal of service condition under Florida law
  • • Onycholysis – Separation of the nail plate from the nail bed, starting at the free edge; causes include trauma, chemicals, infection, and medications
  • • Beau's Lines – Horizontal ridges across the nail plate reflecting a temporary halt in matrix activity (illness, injury, severe stress)
  • • Onychophagy – Compulsive nail biting; can deform the nail plate and damage the nail folds

    • > ### ⚠️ Watch Out For

    > - Onycholysis is a contraindication — do not perform services. It is easily confused with simple nail breakage.

    > - Any sign of infection (redness, swelling, pus, or unusual odor) = refuse service and refer to a physician, no exceptions.

    > - Beau's lines and vertical ridges are different: Beau's lines are horizontal and indicate systemic disruption; vertical ridges are common and generally harmless with age.

    > - Leukonychia (white spots) are often mistaken by clients for fungal infections — know the difference for the exam.

    Manicure Procedures


    Filing Technique

  • • Always file from the outer corners toward the center in one direction
  • • Never saw back and forth — this causes the nail to split or fray
  • • Use the appropriate grit file for the service (lower grit = more abrasive; higher grit = finer/finishing)

    • Nail Shapes


    | Shape | Description |

    |---|---|

    | Oval | Most natural; slightly tapered sides following the fingertip contour |

    | Square | Straight across with sharp corners |

    | Round | Slightly rounded corners; good for short nails |

    | Squoval | Square with softened corners |

    | Pointed/Stiletto | Dramatic taper to a point; less durable |


    > Oval is considered the most natural shape and mirrors the contour of the fingertip.


    Soaking

  • • Soak fingertips in a manicure bowl for approximately 3 to 5 minutes
  • • Over-soaking causes the nail plate to swell and soften → leads to poor product adhesion for enhancements

    • Nail Dehydrator

  • • Applied before nail enhancements
  • • Removes surface moisture and oils from the natural nail plate
  • • Promotes better adhesion of primers, gels, and acrylic products

    • Hand Massage Movements


    | Movement | Technique | Purpose |

    |---|---|---|

    | Effleurage | Light, gliding strokes | Relaxes and introduces massage |

    | Petrissage | Kneading and lifting | Stimulates deeper tissues |

    | Friction | Firm circular motion with thumbs | Stimulates circulation, warms tissue, relaxes muscles |


    Key Terms

  • • Nail Dehydrator – Product that removes moisture and oil before enhancements to improve adhesion
  • • Friction Movement – Firm, circular massage technique using the thumbs; stimulates circulation
  • • Effleurage – Soft, flowing strokes used to begin and end massage

    • > ### ⚠️ Watch Out For

    > - The exam may ask about massage movement types — know friction vs. effleurage vs. petrissage and their specific purposes.

    > - Over-soaking is a common mistake — 3–5 minutes is the correct time; more is not better.

    > - Filing in a back-and-forth "sawing" motion is specifically tested as incorrect technique.

    Pedicure Procedures


    Toenail Trimming

  • • Always trim toenails straight across
  • • Do NOT round or taper corners — this causes ingrown toenails
  • • Use a toenail nipper or straight-edge nail clipper (not curved)

    • Foot Bath Temperature

  • • Recommended water temperature: 100–105°F (37–40°C)
  • • Too hot → risk of burns or discomfort
  • • Too cool → ineffective at softening skin and calluses

    • Pedicure Service Order (General)

    1. Remove polish

    2. Foot soak (100–105°F)

    3. Trim and file toenails (straight across)

    4. Cuticle care

    5. Exfoliation/callus treatment

    6. Massage

    7. Polish application


    Key Terms

  • • Ingrown Toenail – Condition where the nail edge grows into the surrounding skin; often caused by improper trimming technique

    • > ### ⚠️ Watch Out For

    > - Toenails straight across — this is one of the most commonly tested pedicure facts. Rounding = ingrown toenails.

    > - If a client has diabetes or circulatory issues, extra caution is required; some services may be contraindicated — know this for the board exam.

    > - Water temperature questions often appear — memorize 100–105°F specifically.

    Sanitation & Safety – Florida Regulations


    Disposable (Single-Use) Items

    The following must be discarded after use on a single client and cannot be reused:

  • • Nail files
  • • Buffers
  • • Toe separators
  • • Wooden pushers (orange sticks)

    • Reusable Metal Implements

    Proper disinfection procedure for reusable metal tools (nippers, pushers, etc.):

    1. Clean – Remove all visible debris (scrub under running water)

    2. Immerse – Fully submerge in an EPA-registered, hospital-level disinfectant

    3. Soak – For the manufacturer's recommended contact time

    4. Rinse, dry, and store in a clean, closed container


    > ⚠️ Disinfection ≠ Sterilization — Florida cosmetology law requires disinfection, not sterilization, for nail implements.


    Mandatory Refusal of Service

    Florida law requires a cosmetologist to refuse service AND refer to a physician when any of the following are present:

  • • Onychomycosis (fungal nail infection)
  • • Paronychia (bacterial infection around the nail)
  • • Open wounds or sores on the hands or feet
  • • Any signs of infection (redness, swelling, pus, pain, or unusual odor)

    • Key Terms

  • • EPA-registered disinfectant – An Environmental Protection Agency–approved chemical used to kill pathogens on non-living surfaces
  • • Hospital-level disinfectant – The minimum required disinfection level for reusable nail implements in Florida
  • • Single-use item – A product or tool designed for one-time use that must be discarded after the client's service
  • • Contraindication – A condition that prohibits the performance of a service

    • > ### ⚠️ Watch Out For

    > - Florida requires EPA-registered, hospital-level disinfectant — know this specific language for the exam.

    > - Cleaning alone is not disinfecting — you must clean FIRST, then disinfect by full immersion.

    > - A nail file used on one client cannot be stored and used on another, even if it appears clean.

    > - The cosmetologist's responsibility is to refer — not diagnose or treat — nail diseases.
