5.5 Shampooing, Conditioning & Scalp Treatment Services

Key Takeaways

  • Indiana's barber curriculum allots 70 hours to shampoo and massage and 35 hours to scalp treatment, with progress-book minimums of 200 shampoo/massage performances and 50 scalp treatments (820 IAC 8-2-8, 8-2-9).
  • The shampoo service is a scalp manipulation service: effleurage to distribute, then friction with the cushions of the fingertips in a systematic pattern, never the fingernails.
  • Water temperature is tested on the barber's own wrist or inner forearm before it touches the client, and the shampoo bowl must be cleaned and sanitized immediately after use (820 IAC 3-1-7).
  • Conditioners work at three depths: surface rinse-out conditioners, protein or substantive conditioners that penetrate the cortex to rebuild strength, and moisturizing or deep treatments applied with heat.
  • Scalp treatments are selected by scalp condition — normal, dry, oily, or dandruff — and no scalp treatment or massage is performed over abrasions, open lesions, or a suspected infectious condition.

Shampooing, Conditioning & Scalp Treatment Services

Quick Summary: Shampooing is the most-performed service in the shop and it carries 200 required performances in Indiana's student progress book — more than any service except hair styling. The written examination tests it under Content Area II.C, Hair and scalp care services: shampooing and conditioning procedure and products, and scalp treatment and scalp massage procedure and products.


Why the Shampoo Comes First

A shampoo is not a rinse. It is the service that:

  • Removes sebum, perspiration salts, styling product, environmental dust, and loose skin scale so the hair can be cut, styled, or chemically treated predictably;
  • Opens the consultation — the barber's hands are on the scalp, so this is when hair density, elasticity, tension points, and scalp condition are actually felt;
  • Raises scalp circulation through massage manipulation, which is the therapeutic half of the service;
  • Prepares the cuticle so that conditioner, color, or a texture service performs evenly.

[!CAUTION] Shampoo does not precede every chemical service. Do not shampoo before a hydroxide relaxer or before most virgin permanent color applications: the natural sebum layer protects the scalp from the caustic or oxidizing agent, and scalp abrasion from vigorous shampooing dramatically increases chemical burn risk. Shampoo after a relaxer, using the neutralizing shampoo, and shampoo before a thio permanent wave.


The Shampoo Service, Step by Step

  1. Drape. Turn the collar under, place a clean towel lengthwise across the shoulders, and secure the shampoo cape over it so the cape never contacts the neck skin (820 IAC 3-1-11).
  2. Examine the scalp and hair before wetting. Look for lesions, abrasions, scale, pustules, folliculitis, and lice. Anything open, crusted, weeping, or suspected contagious ends the service and becomes a referral.
  3. Comb and detangle from the ends upward with a wide-tooth comb to prevent breakage when wet.
  4. Test the water temperature on your own inner wrist or forearm, then adjust — warm, never hot. Continue to feel the water against the back of your hand at the scalp as you rinse.
  5. Wet thoroughly, shielding the face, ears, and neckline with your free hand.
  6. Apply shampoo to your palm first, emulsify, then distribute — never pour a stripe of concentrate onto one spot.
  7. Manipulate. Begin with effleurage, a light gliding stroke, to distribute product. Move to friction: firm circular movement using the cushions of the fingertips, never the nails. Work a repeatable pattern — hairline to crown, then both sides, then the nape — so no zone is missed.
  8. Rinse completely. Residue is the most common cause of dull hair, itch, and flaking. Lift at the nape and rinse until the hair squeaks slightly, then rinse once more.
  9. Repeat the lather only if needed — heavily soiled or product-loaded hair only.
  10. Apply conditioner, comb through, respect the manufacturer's timing, and rinse.
  11. Towel blot, do not rub. Rubbing roughens the cuticle and creates frizz and breakage.
  12. Clean and sanitize the bowl immediately after use (820 IAC 3-1-7(c)), and place the used towel and cape in the covered hamper (820 IAC 3-1-10(b)).

Shampoo selection

TypeChemistry / purposeIndicated for
Plain / balancedpH-balanced cleansing surfactantsNormal hair and scalp
ClarifyingHigher-detergency surfactant plus chelating agentProduct buildup, mineral deposits from hard water, before a corrective color
Moisturizing / conditioningCleanser plus humectants and emollientsDry, coarse, or chemically treated hair
Medicated / anti-dandruffZinc pyrithione, selenium sulfide, ketoconazole, coal tar, or salicylic acidDandruff and seborrheic scale — dispensed and used per label, never as a diagnosis
NeutralizingAcid-balanced, often with a color indicatorImmediately after a hydroxide relaxer, to drive pH down and stop lanthionization
Dry / powderAbsorbent starch or clayClients who cannot be wet-shampooed

Water hardness matters: hard water carries calcium and magnesium salts that reduce lather and leave film, and it is corrected with a chelating or clarifying shampoo. Soft water lathers readily.


Conditioners: Three Depths of Action

ClassWhere it worksFunctionTypical use
Rinse-out / instant conditionerCuticle surfaceDetangles, smooths the cuticle scale, adds slip and shineEvery shampoo service
Protein / substantive conditionerPenetrates the cortexHydrolyzed protein temporarily rebuilds and reinforces damaged keratin, raising tensile strengthOver-processed, porous, or chemically damaged hair
Moisturizing / deep (treatment) conditionerCortex, with heatHumectants and emollients restore moisture balance; applied under a warm towel, cap, or hood for the labeled timeDry, brittle, or coarse hair; corrective work

Two more the exam names:

  • Leave-in conditioner / detangler — light, not rinsed, for daily manageability.
  • Acid-balanced (acidifying) rinse or finishing rinse — closes and hardens the cuticle after an alkaline service and restores surface pH.

[!NOTE] Protein and moisture are a balance, not a contest. Hair that is limp, mushy, and over-stretchy when wet is moisture-overloaded and needs protein. Hair that is stiff, rough, and snaps with no stretch is protein-overloaded and needs moisture. Test elasticity before choosing.


Scalp Treatments and Scalp Massage

A scalp treatment combines product with systematic manipulation to improve scalp health, and Indiana requires 50 of them in the student progress book.

Scalp conditionSignsTreatment approach
NormalClean, flexible, no scale or excess oilMaintenance: mild shampoo plus general massage to stimulate circulation
DryTight scalp, fine scale, dull hair, little shineMoisturizing or emollient scalp preparation, gentle steam or a warm towel, avoid strong or drying shampoos and high alcohol tonics
OilyGreasy at the roots within a day, visible shine, product slidesCleansing manipulation to loosen sebum, normalizing or astringent tonic, avoid heavy occlusive oils
Dandruff (pityriasis)Loose white or greasy yellowish scale, itchMedicated shampoo and topical per label, gentle manipulation; persistent or inflamed cases go to a physician
Corrective / thinningDiffuse thinning, breakage at tension pointsStimulating manipulation and scalp tonic to support circulation; nothing is claimed to regrow hair

Massage technique

  • Effleurage — light, continuous gliding; the opening and closing movement of every scalp service.
  • Petrissage — kneading and lifting the scalp tissue between the fingers.
  • Friction — deep circular movement with the fingertip cushions; the workhorse of scalp stimulation.
  • Vibration — rapid shaking transmitted through the fingertips; used sparingly and briefly.
  • Keep one hand in contact with the client throughout, and work in a fixed pattern so coverage is complete and symmetric.

Contraindications — the service does not happen

  • Abrasions, cuts, open or weeping lesions, or crusts anywhere on the scalp
  • Suspected fungal or bacterial infection: Tinea capitis, folliculitis, furuncle, carbuncle, impetigo-like crusting
  • Head lice (pediculosis capitis) — refuse, refer, and disinfect everything that contacted the client
  • Severe inflammation, sunburn, or scalp psoriasis in an acute flare
  • Immediately following a chemical service, when the scalp is already sensitized
  • Any condition currently under a physician's care, absent the client's clearance
