Performing nail care services requires meticulous preparation of both the skin and nails to ensure client safety, comfort, and optimal results. In Kenya’s cosmetology sector, professionals working in salons, spas, and wellness centers must adhere to high standards of hygiene and technique to prevent infections and provide quality service. Proper preparation also enhances the effectiveness of subsequent treatments such as polishing, shaping, and cuticle care. This chapter focuses on the essential steps and considerations involved in preparing the skin and nails before any nail care procedure.

2.1 Skin and nails preparation

Skin and nails preparation is the foundational step in any nail care service, crucial for achieving professional and hygienic results. It improves the appearance and health of the client's hands and feet and lowers the risk of infection and allergic reaction. Proper preparation involves sanitising, shaping the free edge, smoothing the nail surface, and assessing and protecting the condition of the skin and nails.

Sanitize

Sanitising removes dirt, oils and microorganisms from the client's skin and nails, from the technician's hands and from the tools, so that nail products bond properly and infection is not passed from one client to another. It is the first hands-on step of every manicure or pedicure. Example: before a manicure, the technician washes the client's hands, wipes each nail with 70% isopropyl alcohol on a lint-free pad, and only then opens the clean tool pouch.

Materials used for sanitising:

Procedure for sanitising the client and workstation:

1. Wash your own hands with soap and water, dry them with a clean towel and put on disposable gloves. This protects the client and you from cross-contamination.
2. Wipe the work surface with disinfectant and lay a clean towel. Set out only tools that have been cleaned and disinfected, and open single-use items in front of the client.
3. Remove any old polish with a suitable remover on a lint-free pad. Polish and oils left on the nail stop products from adhering.
4. Wash the client's hands or feet with mild soap and warm water, paying attention to the nail folds and under the free edge, where debris collects.
5. Rinse thoroughly with clean water so that no soap residue irritates the skin or weakens polish adhesion.
6. Pat the skin and nails dry with a clean disposable towel. Moisture left on the skin encourages microbial growth.
7. Apply 70% isopropyl alcohol or nail sanitiser with a lint-free pad over each nail plate, under the free edge and on the surrounding skin, then allow it to air-dry.
8. Check the skin for cuts or broken areas before continuing. Do not carry on over broken skin, and cover or avoid the area as appropriate.

Sanitising tools between clients:

• Clean first: Remove visible debris from metal tools with soap, water and a brush, because disinfectant cannot work through dirt.
• Disinfect metal tools: Use a suitable disinfectant at the manufacturer's dilution and for the stated contact time, then dry and store the tools in a clean, closed container.
• Discard porous items: Wooden sticks, emery boards and paper buffers cannot be disinfected. Give them to the client or throw them away after one use.
• Keep clean and used tools apart: Use separate, labelled containers so a used tool is never picked up for the next client by mistake.
• Change towels and liners: Use a fresh towel or liner for every client.

Filing

Filing shapes the free edge of the nail and sets its length before any other treatment. A well-filed nail looks even, resists snagging and splitting, and gives the nail a base for polish or later enhancements. Example: a client who keeps catching her nails on clothing asks for shorter nails, and the technician files them to a soft squoval shape with a fine-grit file.

Common shapes:

• Square: The free edge is straight across with sharp corners. It suits strong nails but the corners can snag.
• Squoval: A square nail with softened corners. It is strong and practical for everyday wear.
• Round: The free edge follows the curve of the fingertip. It suits short nails and clients with active hands.
• Oval: A longer, tapered curve that makes the finger look slimmer. It needs enough nail length to look balanced.
• Almond or pointed: A tapered shape ending in a softened point. It needs strong nails and is more easily broken.

Files used in nail preparation:

A lower grit number means a coarser file and a higher number means a finer file. Use a medium to fine grit on natural nails and a coarser grit only where heavy shortening is needed.

Procedure for filing:

1. Sanitise the hands and use a clean or new file. A shared, dirty file can pass infection between clients.
2. Check that the nails are dry. Wet nails are soft and peel or tear when filed.
3. Agree the length and shape with the client, and look at the client's nail strength and finger shape before you begin.
4. Hold the client's finger steady and place the file at a slight angle under the free edge.
5. File from the side towards the centre of the nail in one direction. Do not saw back and forth, because this causes splitting and layering.
6. Shape one side, then the other, and keep checking that both sides match.
7. Soften sharp corners and smooth the underside of the free edge by lightly running the file along it.
8. Brush away the filings with a clean brush or lint-free pad and check the shape from the client's point of view.

Points to remember:

• Toenails: File toenails straight across with only the corners lightly smoothed, which lowers the risk of ingrown nails.
• Pressure: Use light, even strokes. Heavy pressure produces heat and weakens the nail.
• Hygiene: Never file over broken skin or an infected nail.

Buffing

Buffing smooths ridges on the nail plate and removes dullness, leaving an even surface that takes polish well and reflects light. It is done after filing and with light pressure, because the natural nail plate is thin. Example: a client with mild vertical ridges has her nails buffed with a fine block, which makes the surface look even before base coat is applied.

Buffing tools:

Procedure for buffing:

1. Make sure the hands are sanitised and the nails are clean and dry.
2. Check each nail for thinness, damage or infection. Do not buff a nail that is thin, split or inflamed.
3. Start with the coarsest side of the block only if ridges need smoothing, otherwise begin with a medium side.
4. Buff with light pressure in one direction from the cuticle area to the free edge. Keep the block moving.
5. Spend only a few seconds on each nail, since friction creates heat that can cause discomfort and thinning.
6. Move to the finer sides of the block to refine the surface and bring up shine.
7. Wipe away the dust with a clean brush or lint-free pad.
8. Ask the client about any warmth or discomfort and tell her not to over-buff at home.

Cautions:

• Over-buffing: Too much buffing thins the nail plate and can make it weak and sensitive.
• Frequency: Buff only occasionally, with enough time between sessions for the nail to recover.
• Hygiene: Use a single-use buffer or a block that has been properly cleaned and is only used on one client.

Softening the skin and nails

Softening the skin and nails prepares them for cuticle care and reduces discomfort during shaping. In dry conditions the skin around the nails can harden and the nails become brittle, so this step matters most for dry or rough hands. Example: a client with dry, hard cuticles has her hands soaked in warm, mildly soapy water before cuticle work begins.

• Soaking in warm water: Submerge the hands or feet in warm water with mild soap or a moisturising agent to soften the cuticles and surrounding skin.
• Cuticle softener: Apply a cuticle softener, often containing glycerin or an oil such as jojoba, to loosen dead skin around the nail plate.
• Moisturising creams and oils: After soaking, massage an emollient cream or oil into the skin to improve hydration and elasticity.
• Timing: Soak for about 5 to 10 minutes, shorter for skin that softens quickly, to avoid over-softened tissue that tears easily.
• Temperature control: Keep the water comfortably warm, around 37°C to 40°C, so that it is effective without burning or chilling the client.

Assessing nail and skin health before service

A thorough assessment shows whether the service is safe and which products and techniques suit the client. A technician who spots a problem early can adjust the service or refer the client. Example: a client has a red, swollen nail fold, so the technician explains that she cannot work on it and advises seeing a medical professional.

• Visual inspection: Look for discolouration, swelling, redness or deformities that may suggest a fungal infection such as onychomycosis or a bacterial infection such as paronychia.
• Skin integrity: Check for cuts, abrasions, eczema or psoriasis, which nail care can aggravate.
• Nail texture and shape: Note brittleness, ridges or unusual thickness, which may point to damage or a health condition.
• Client medical history: Ask about diabetes, allergies and recent treatments that could affect nail health or rule out certain products.
• Client comfort and sensitivity: Ask about pain, itching or discomfort so that you can adapt the procedure.

Protecting the skin and nails prior to treatment

Protection shields the skin and nail plate from damage during the service and helps the finished result last. It is done after sanitising and before products are applied. Example: before applying coloured polish, the technician applies a base coat to prevent staining and to give a smooth surface.

• Cuticle barrier creams: Shield the delicate skin around the nail from harsh chemicals in nail products.
• Base coats: Protect the nail plate from staining and give polish a smooth surface to grip.
• Use of gloves: Disposable gloves keep the technician's hands hygienic and protect both parties from infection.
• Avoiding over-trimming: Removing too much cuticle exposes the skin to infection, so trim carefully with disinfected tools.
• Client education: Advise clients to wear gloves for washing-up and cleaning, since harsh detergents damage skin and nails.
