NAIL DISEASES AND NAIL DISORDERS (NAIL CARE-G9-W1-L2)

Summary

The lesson introduces nail diseases and disorders, explains how nail changes may reflect injury, infection, or broader health problems, and emphasizes sanitation in nail care.

Main Ideas

• Nails can offer clues about health. Changes in nail color, shape, thickness, or condition may be associated with injury or health issues. For example, bluish nails may indicate inadequate oxygen or problems involving the lungs or heart. The lesson recommends consulting a doctor.
• Onychosis is any disease, disorder, or condition affecting the nails.
• Infection prevention matters in salon work. The lesson defines pus as yellowish fluid from a wound and a sign of infection, fungi as organisms that may cause infections, and sterilization as the destruction of microorganisms. Salon tools and equipment should be properly sterilized.
• Good nail and hand care includes gentle filing, moisturizing, careful trimming, avoiding pressure on affected nails, keeping nails clean and dry, and protecting skin from harsh chemicals. The stated competency is to wash a client’s hands with warm, soapy water and towel-dry them before and after cleaning.

Nail Conditions Discussed

• Bluish nails: May indicate low oxygen or certain lung or heart problems. The lesson recommends seeking medical advice and handling any manicure gently.
• Bruised nail: An injury to the nail plate can trap blood beneath it and cause discoloration.
• Corrugations: Wavy ridges associated in the lesson with uneven nail growth, illness, or injury. Buffing is suggested to reduce their appearance.
• Burrs (hangnails): Loose, split skin near the cuticle, attributed to dry cuticles or environmental effects. The lesson recommends trimming them carefully and moisturizing with cuticle oil.
• Koilonychia (spoon-shaped nails): Concave, thin nails with raised grooves. The lesson associates this condition with iron-deficiency anemia and advises gentle filing and protective nail polish.
• Leukonychia: White spots that generally grow out and are not necessarily a sign of disease. The lesson suggests dietary zinc and limiting nail-polish use.
• Onychorrhexis (brittle nails): Associated in the lesson with injury, improper filing, harsh chemicals, and possibly thyroid disease. It recommends softening nails before trimming and moisturizing them.
• Onychauxis (thickened nails): Excessive nail thickening. The lesson suggests filing and smoothing if there is no infection.
• Onychatrophy (nail atrophy): Loss or reduction of the nail plate, potentially related to trauma or disease. The lesson recommends gentle filing and limiting exposure to water, detergents, and chemicals.
• Onychophagia (nail biting): A habit associated with stress or anxiety. The lesson advises avoiding biting and getting manicures regularly.
• Pterygium: Skin growing inward over the nail plate, potentially leading to scarring and nail loss. The lesson advises against removing it yourself and recommends seeking medical advice.
• Onychocryptosis (ingrown nail): The nail grows into the surrounding skin and may become infected. Proper trimming and comfortable, wide-toed shoes are recommended.
• Onychogryphosis: Increased nail thickness and curvature, which may cause pain or inflammation if the nail presses into the skin. The lesson recommends moisturizing and trimming the nail and avoiding tight shoes.
• Onycholysis: Loosening of the nail, which the lesson links to internal disorders, infection, or medication. It advises keeping nails short, avoiding polish and irritants, and using an emollient.
• Onychomycosis (nail fungus): A fungal infection described as causing whitish, scrapeable spots. Prevention advice includes keeping nails clean and dry, using antifungal products, and avoiding damage to the skin around toenails.
• Paronychia: Inflammation of the skin around a nail, with redness, swelling, and tenderness, attributed to bacteria. The lesson recommends keeping hands and feet clean and dry, wearing lined gloves when handling water or harsh chemicals, and avoiding cutting or pushing back cuticles.
• Nail loss: Complete or partial loss of nails may follow illness, fever, medication, or trauma. The lesson recommends wearing well-fitting shoes and thoroughly drying nails.

Infection and Prevention Concepts

Diseases may be contagious, spreading through direct or indirect contact, or non-communicable, meaning they do not spread from person to person.

The lesson gives tuberculosis, colds, ringworm, scabies, head lice, and viral infections as examples of contagious conditions. It notes that coughing, sneezing, handwashing, shared utensils, and salon equipment can affect transmission.

Examples of non-communicable conditions include genetic diseases, cancer, mental disorders, autoimmune diseases, and heart disease.

The lesson emphasizes pairing knowledge with preventive practices and proper sanitation to protect both clients and beauticians.

Practice Activities

The video includes matching and multiple-choice exercises about nail-condition terms. Questions cover nail fungus, pus, ingrown nails, increased nail curvature, and inflammation around the nail. Learners are also asked to classify several terms as nail diseases or disorders.

Some terms and quiz answers appear garbled or inconsistent in the auto-generated subtitles. For example, the answer to the nail-fungus question is transcribed as “onychomadesis,” although the listed matching term is “onychomycosis.”
