Performing hair addition services requires meticulous preparation of the client’s natural hair to ensure the added hair integrates seamlessly and lasts as intended. In Kenya’s cosmetology sector, particularly in urban salons and beauty clinics, proper hair preparation is crucial for client satisfaction, maintaining scalp health, and achieving professional results. This chapter explores the essential steps and considerations involved in preparing a client’s hair before applying hair additions. Understanding these procedures supports cosmetologists in delivering quality services that enhance client confidence and uphold industry standards.

2.1 Client’s Hair Preparation

Client's hair preparation is the work done on the natural hair before a hair addition service: undoing any old style, shampooing, conditioning and blow drying the hair so it is clean, soft, detangled and dry. Good preparation removes build-up and shed hair, makes the hair easier to section, reduces breakage under the tension of braids or weaves and stops dampness and odours under the new style. The findings of the hair and scalp analysis decide the products used at each step (see Hair and scalp analysis). Example: a client arrives wearing old box braids, so the stylist takes them down, washes and deep conditions her hair, then blow-dries it on medium heat before sectioning it for a sew-in weave.

Undoing

Undoing is the careful removal of the client's previous hair addition style, such as braids, cornrows, weaves or crochet, before the new service. It must be done gently, because natural hair that has been held in a style sheds and tangles, and pulling or cutting carelessly causes breakage. Shed hair is combed out and the scalp is checked once the style is removed. Example: before a new crochet style, the stylist cuts each old braid just below the end of the client's natural hair, unravels it and softens tangles with a little conditioner and her fingers.

1. Protect the client: drape the client and place a towel around the shoulders.
2. Find the natural hair length: check where the client's own hair ends inside each braid or weave.
3. Cut carefully: cut the extension hair below the end of the natural hair, never into the client's own hair.
4. Unravel the hair: unravel braids or unpick weave thread from the end towards the root, working slowly.
5. Soften tangles: apply a little conditioner, oil or detangling spray to loosen knots and shed hair.
6. Remove shed hair: finger-detangle, then comb gently with a wide-tooth comb from the ends upwards.
7. Check the scalp: look for build-up, flaking, sores or thinning before continuing.

Shampooing

Shampooing is washing the natural hair and scalp with shampoo and water to remove dirt, oil, sweat, dead skin and product build-up. Hair that has been in a style for weeks often has heavy build-up, which can make new braids slip, cause itching and leave odours under the style. A clarifying shampoo removes build-up, while a moisturising shampoo suits dry hair. Example: a client whose old braids were in for several weeks has her hair shampooed twice, first with a clarifying shampoo and then with a moisturising one.

1. Seat and protect the client: seat the client at the washing basin with a towel and draper in place.
2. Test the water: check the water temperature on your wrist and ask the client if it is comfortable.
3. Wet the hair: wet the hair thoroughly from root to ends.
4. Apply shampoo: apply shampoo to the scalp, working in small sections for thick hair.
5. Massage the scalp: massage with the pads of the fingers, not the nails, to lift dirt and build-up.
6. Rinse: rinse thoroughly with lukewarm water until no foam remains, repeating if the hair is heavily soiled.
7. Blot: squeeze excess water from the hair and wrap it in a clean towel.

Conditioning

Conditioning is applying a conditioner after shampooing to soften, moisturise and detangle the hair and smooth the cuticle. Conditioned hair is easier to comb and section, and it bends without breaking under the tension of braiding and weaving. Deep conditioning under a steamer or warm towel helps very dry or chemically treated hair. Example: a client with dry, coarse natural hair has a deep conditioner applied and sits under a steamer before the stylist detangles and dries it.

1. Remove excess water: blot the hair so the conditioner is not diluted.
2. Choose the conditioner: select a rinse-out, deep or leave-in conditioner to suit the hair.
3. Apply in sections: apply from mid-lengths to ends, then lightly to the roots, section by section.
4. Detangle: comb gently through with a wide-tooth comb from the ends upwards.
5. Process: leave for the time the product directs, under a steamer or warm towel for a deep conditioner.
6. Rinse: rinse with lukewarm water, unless it is a leave-in product.
7. Blot dry: wrap the hair in a towel and blot out excess water.

Blow drying

Blow drying is drying and stretching the hair with a hand-held blow dryer before hair additions are fitted. Fully dry hair is essential, because hair braided or sewn while damp can develop odours and mould under the style, and stretched hair is easier to section neatly. Medium heat and a heat protection product are used to avoid heat damage. Example: before cornrowing for a weave, the stylist blow-dries the client's hair in sections on medium heat with a comb attachment, stretching it so the partings are straight.

1. Apply heat protection: apply a light heat protection product to towel-dried hair.
2. Section the hair: divide the hair into four or more sections with clips.
3. Set the dryer: choose a medium heat setting and fit a nozzle or comb attachment.
4. Dry section by section: dry each section from root to ends, stretching the hair with the comb or brush.
5. Keep the dryer moving: keep the dryer moving and away from the scalp to avoid burns.
6. Check for dampness: feel the roots and the nape to make sure the hair is completely dry.
7. Finish with cool air: use the cool setting to set the stretch and reduce frizz.

Detangling and sectioning

• Gentle detangling: Use a wide-tooth comb and fingers, working from the ends towards the roots to avoid breakage.
• Moisture while detangling: Use a light detangling spray or leave-in conditioner to reduce friction.
• Sectioning: Divide the hair into manageable sections with clips so the stylist can work systematically.
• Natural partings: Note the natural partings and growth direction so the added hair lies naturally.
• Hairline and nape: Section the hairline and nape separately and handle them gently, as they are fragile and most visible.

Protecting the natural hair during preparation

• Avoid excessive tension: Do not pull the hair tightly while detangling and sectioning, to prevent traction alopecia.
• Limit heat: Use medium heat and heat protection when blow drying.
• Avoid heavy oils: Avoid heavy oils before braiding, as they make the hair slippery and braids may slip.
• Limit chemicals: Avoid relaxing or colouring just before a hair addition service.
• Clean tools: Use combs, brushes and clips that have been cleaned and disinfected.
