10.3 Shampoo Procedure & Scalp Massage

Why Procedure Questions Matter

The practical side of the PSI exam assumes you can perform a shampoo service in a safe, ordered, client-protective way, and the written exam mirrors that with sequence and safety questions. Common traps include draping errors, using nails instead of fingertip pads, water that is too hot, and massage performed over a contraindicated scalp. Learn the procedure as a numbered sequence and the safety rules as absolutes.

Pre-Service Steps

1. Consultation: ask about the client's hair history, scalp concerns, recent chemical services, and what outcome they want today. Record anything relevant.
2. Analysis: examine the hair (texture, porosity, elasticity, condition) and the scalp (dry, oily, flaking, or any disorder). Analysis drives product choice and determines whether massage is safe. Any suspected scalp disease means you do not proceed with the service — refer the client to a physician.
3. Draping: protect the client before any water or product touches them. For a shampoo or wet service, use wet draping: a neck strip or towel under a cape, with a towel tucked to catch water. For chemical services, use chemical draping: a waterproof cape (often a second towel as well) so chemicals cannot soak through to skin or clothing. The exam distinction: chemical services get the waterproof cape; the cape is fastened so it does not touch the client's skin directly at the neck.
4. Brushing: brush the hair before wetting, working from the ends upward, to remove tangles and surface debris and to stimulate the scalp. Brushing first means fewer tangles tighten into knots once the hair is wet.

Water Temperature and Cleansing Technique

Test the water on your own wrist or hand before it touches the client, and adjust until the client confirms it is comfortably warm — never hot. Keep the spray directed so water does not run into the client's ears, eyes, or face, and keep one hand positioned to shield the hairline when rinsing the front.

Apply the amount directed on the product label and work systematically with the pads of the fingertips. Rinse completely. Analyze the result and repeat only if soil or residue remains and another application is appropriate for the hair, scalp, and product; exactly two applications are not a universal requirement.

Technique rules that appear constantly on exams:

• Use the pads (cushions) of the fingertips, never the fingernails. Nails scratch the scalp and can create openings for infection.
• Work in systematic sections — front hairline, crown, sides, nape — so no area is missed and the whole scalp receives even attention.
• Rinse thoroughly until the water runs clear and the hair squeaks slightly; leftover shampoo dulls the hair, irritates the scalp, and interferes with conditioners and chemical services.

Scalp Massage Manipulations

Scalp massage during the shampoo relaxes the client and stimulates blood circulation to the scalp, which promotes relaxation and temporarily increases local circulation. The five classic manipulations:

Keep movements rhythmic, maintain contact with the scalp rather than sliding hair against hair (which tangles), and keep pressure moderate and consistent. Massage during the shampoo is normally performed with the lather itself or with a scalp massage cream providing slip.

Massage Contraindications

Do NOT perform scalp massage when analysis reveals any of the following:

• Scalp disorders or infections — pustules, open sores, suspected ringworm, lice, or any contagious condition (stop the service entirely and refer out).
• Abrasions, recent injury, or recent scalp surgery in the area.
• High blood pressure or certain heart/circulatory conditions — vigorous stimulating massage is avoided or performed only with physician approval, since it increases circulation.
• When in doubt, skip the massage and keep the service gentle; the exam answer for any questionable scalp is to avoid manipulation and refer to a physician.

Safety Throughout the Service

Protect the client's clothing with correct draping and a towel at the nape; protect the eyes from shampoo and rinse water with a shielding hand or a damp towel when working the front hairline; check water temperature before and during the rinse; and angle the head and spray so water never enters the ears. Squeeze excess water from the hair before applying conditioner so the product is not diluted.

Post-Shampoo Handling

After the final rinse, gently squeeze — never wring or roughly rub — the water from the hair, then wrap or blot with a clean towel. Rough towel rubbing roughens the raised wet cuticle and causes breakage and frizz. Detangle with a wide-tooth comb, starting at the ends and working upward in small sections toward the scalp; starting at the roots drags knots together and snaps wet hair, which is at its weakest when saturated. Finish with the chosen conditioner or treatment per the previous section, then proceed to the styling service.

Complete Procedural Sequence

1. Consult with the client and review their history.
2. Analyze the hair and scalp; decide on products and whether massage is safe.
3. Drape appropriately for the service (wet or chemical draping).
4. Brush the hair from ends to roots.
5. Seat the client comfortably at the bowl; test water temperature.
6. Wet the hair thoroughly, protecting eyes, ears, and clothing.
7. Apply shampoo; first lather to remove surface soil; rinse.
8. Apply shampoo again; second lather to cleanse, working systematically with fingertip pads.
9. Perform scalp massage manipulations as indicated and safe.
10. Rinse thoroughly until the water runs clear.
11. Gently squeeze out excess water; apply conditioner or treatment per directions.
12. Rinse as required, blot with a towel, and detangle with a wide-tooth comb from the ends upward.
