Key Takeaways

  • Select shampoo based on the client's specific hair and scalp condition - one size does NOT fit all
  • Always use the cushions of your fingertips during scalp massage, NEVER fingernails
  • Ideal shampooing water temperature is 100-105°F (38-41°C); final rinse with cool water seals the cuticle
  • Apply conditioner primarily to mid-lengths and ends, avoiding the scalp unless treating scalp conditions
  • Protein treatments strengthen weak, damaged hair while moisturizing treatments add hydration to dry hair

Shampooing and Conditioning

Shampooing and conditioning are fundamental services that form the foundation of all hair care. Understanding product selection, proper techniques, and scalp treatments is essential for the NIC cosmetology exam and professional practice.

The Purpose of Shampooing

Shampoo serves multiple functions:

  • Primary: Cleanse the scalp and hair of dirt, oil, debris, and product buildup
  • Secondary: Prepare hair for other services (color, perms, styling)
  • Therapeutic: Treat specific scalp conditions when using medicated formulas

Anatomy of Shampoo

All shampoos contain similar basic components:

SurfactantsCleansing agentsSodium lauryl sulfate, sodium laureth sulfate, cocamidopropyl betaine
Conditioning agentsAdd softnessFatty alcohols, quaternary ammonium compounds
PreservativesPrevent spoilageParabens, phenoxyethanol

Oily hair, oily scalpClarifying (mild)Removes excess sebum
Color-treated hairColor-protecting, sulfate-freePrevents color fading
Fine, limp hairVolumizingAdds body without weighing down
Damaged, brittle hairStrengtheningRepairs and fortifies
Product buildupClarifyingRemoves residue
DandruffMedicatedTreats fungal cause

Proper Shampooing Technique

Step 1: Preparation

  • Drape client properly (waterproof drape under towel)
  • Remove tangles with wide-tooth comb
  • Adjust shampoo bowl for client comfort
  • Test water temperature on inner wrist (100-105°F / 38-41°C)

Step 2: Wetting

  • Protect face and ears from water spray
  • Saturate hair thoroughly with warm water
  • Use moderate, consistent water pressure
  • Ensure complete saturation from scalp to ends

Step 3: Application

  • Dispense appropriate amount of shampoo (quarter to half-dollar size)
  • Emulsify in palms before applying
  • Apply to scalp first, then work through lengths
  • Use firm but gentle pressure

Step 4: Manipulation

  • Use the cushions of your fingertips, NEVER fingernails
  • Work in circular motions on scalp
  • Manipulate for 2-3 minutes minimum
  • Cover entire scalp systematically

Step 5: Rinsing

  • Rinse thoroughly until water runs clear
  • Remove ALL shampoo residue
  • Repeat if necessary (second shampoo often lathers better)
  • Gently squeeze excess water before conditioning

Conditioning Treatments

Conditioners restore moisture, improve manageability, and protect hair from damage.

Conditioner TypeProcessing TimeBest ForHow It Works
Instant/Rinse-Out1-5 minutesNormal hair; daily useCoats cuticle; adds slip
Leave-InNone (not rinsed)Dry, tangled, damaged hairContinuous protection
Deep Conditioning/Mask10-30 minutesVery dry, damaged hairPenetrates cortex
Protein Treatment5-20 minutesWeak, brittle, over-processed hairStrengthens cortex
Moisturizing Treatment10-20 minutesDry, dehydrated hairAdds hydration
Hot Oil Treatment5-10 minutes with heatVery dry hair and scalpIntense moisture; seals cuticle

Proper Conditioning Technique

  1. Gently squeeze excess water from hair
  2. Dispense appropriate amount based on hair length/density
  3. Apply primarily to mid-lengths and ends (avoid scalp unless scalp treatment)
  4. Distribute evenly with fingers or wide-tooth comb
  5. Process according to manufacturer's directions
  6. Rinse thoroughly with cool water (seals cuticle)

Scalp Treatments

Treatment TypePurposeWhen to Use
Dry Scalp TreatmentAdd moisture; relieve itchingDry, flaky, tight scalp
Oily Scalp TreatmentBalance sebum productionExcessively oily scalp
Exfoliating TreatmentRemove dead skin cells, buildupFlaky scalp; before chemical services
Stimulating TreatmentIncrease blood circulationSluggish scalp; thinning hair
Antiseptic/MedicatedTreat dandruff, fungal conditionsDandruff; seborrheic dermatitis

Water Temperature Guidelines

TemperatureFahrenheitCelsiusUse For
Cool60-75°F15-24°CFinal rinse (seals cuticle); color-treated hair
Warm100-105°F38-41°CStandard shampooing and conditioning
HotAbove 105°FAbove 41°CGenerally NOT recommended (can burn scalp, strip color)

Water Pressure Guidelines

  • Light pressure: Sensitive scalp, elderly clients, after chemical services
  • Moderate pressure: Standard services, most clients
  • Firm pressure: Deep cleansing, scalp stimulation (if client is comfortable)

Always ask the client about their temperature and pressure preferences!
