Nail Conditions Overview

Nail Conditions

• Nail conditions arise from trauma, neglect, or underlying health issues, often resulting in symptoms like discoloration and changes in texture.
• Regular nail care and hygiene can prevent many nail conditions, emphasizing the importance of maintenance.
• Agnails (hangnails) occur at nail corners; they heal in 3-5 days with trim and moisturizing to prevent infection.
• Bruised nails show discoloration; treatment involves avoiding pressure as the nail grows out.
• Leukonychia involves small separations from the nail bed, requiring regular nail services to monitor for underlying issues.
• Pterygium is excess skin attached to the nail plate, hindering growth and may need medical intervention with no nail services allowed.
• Beau's lines indicate past trauma and nails can recover post-healing; clients should be educated on possible causes.
• Onychophagy (nail biting) ceases when biting stops, with weekly services promoting healthy regrowth.
• Onychorrhexis requires gentle filing and moisturizing, alongside regular monitoring for changes.

Nail Diseases

• Nail diseases stem from infections or systemic health issues, causing symptoms like discoloration and structural changes.
• Early diagnosis is crucial in preventing complications from diseases, especially infectious ones.
• Onychomycosis (tinea unguium) is a fungal infection leading to thickened nails, often treated with antifungal medications.
• Tinea manus is ringworm of the hand, treated with antifungal creams or oral medications.
• Tinea pedis, ringworm of the feet, causes itching and peeling, treated with antifungal powders or sprays.
• Paronychia indicates inflammation around the nail, characterized by redness and swelling; may require warm soaks and antibiotics.
• Onychoptosis is the shedding of nails that regrow once the underlying condition is treated.

Skin Structure and Functions

• Skin comprises three layers: epidermis (outermost, protective barrier), dermis (thicker, elastic connective tissue), and subcutaneous tissue (supporting layer with fat).
• The dermis consists of papillary (rich in blood vessels and tactile sensory receptors) and reticular layers (houses sweat glands and provides strength).
• Sudoriferous glands regulate temperature; sebaceous glands produce sebum to prevent dryness and maintain pH.
• Subcutaneous tissue cushions the skin, acts as a shock absorber, and contains blood vessels and nerve endings.

Hair Treatments and Chemical Processes

• Chemical relaxers straighten hair by breaking disulfide bonds; sodium hydroxide relaxers are for tightly curled hair with a pH of 11.5-14.
• Mild relaxers suit healthy or color-treated hair, while super relaxers target coarse or resistant hair; avoid on porous or previously treated hair.
• Perming alters hair structure for curls or waves; alkaline perms (pH 8.0-9.5) use heat, while acid perms (pH 6.0-7.2) minimize swelling with firm tension.

Nail Anatomy and Disorders

• Nails (onyx) are skin appendages, with common disorders including blue nails and onychocryptosis (ingrown nails).
• Treatments often involve careful manicuring, advising clients to seek medical attention where necessary.

Massage Techniques and Benefits

• Effleurage consists of light strokes for relaxation, petrissage involves kneading to stimulate muscles, and tapotement uses tapping movements to improve circulation.

Introduction to Trichology

• Hair comprises the hair root (living part) and fiber (dead cells), with follicle shape dictating the hair type (straight, wavy, curly).
• Hair growth phases include the anagen (active growth), catagen (transitional), and telogen (resting and shedding).
• Factors affecting hair growth include genetics, hormonal changes, nutritional deficiencies, and environmental impacts.

Introduction to Onychology

• Nails are keratin-based appendages studied in onychology; nail structure includes the nail plate, bed, cuticle, and lunula (visible nail matrix).

Sterilization and Disinfection in Trichology and Onychology

• Sterilization eliminates all microbes on skin-piercing tools; disinfection targets certain microbes on non-blood-contact tools, ensuring safe practices.
