Itchy Scalp With Cradle Cap-Like Flaking
A 52-year-old man comes in for a shampoo and cut. On examination his scalp shows greasy, yellowish scales adherent to the scalp, especially around the hairline and behind the ears, with mild redness underneath. He reports itching that is worse in winter and after sweating, and he has been scratching. He has no open sores, no pus, and no hair loss. He asks you to 'scrub it all off' with a strong exfoliating shampoo and a hard scalp massage. He also mentions he started a new medicated shampoo from the pharmacy last week but cannot remember the name.
1. What is your working assessment of the scalp condition, and what in the history supports it?
Read the worked answer
The picture - greasy yellowish adherent scales at the hairline and behind the ears, mild underlying erythema, itching worsened by sweat and cold weather, no pustules or hair loss - is most consistent with seborrhoeic dermatitis (or a seborrhoeic scalp condition). Supporting features: distribution in oily areas, greasy rather than dry flaking, chronic/recurrent course, and itching.
It is not a diagnosis to be made definitively in the salon, but it guides safe practice:
- No signs of infection (no pus, no open sores) or scarring alopecia.
- The condition is manageable but often recurrent; salon care supports, not replaces, medical treatment.
- Because he is already using a pharmacy product, avoid layering unknown actives and refer to his pharmacist/GP if it is worsening.
2. How should you modify the shampoo and scalp massage he requested, and why?
Read the worked answer
Do not use a harsh exfoliating scrub or aggressive massage on an inflamed, scaling scalp - friction can worsen erythema, cause micro-abrasions and increase itching.
Modify as follows:
- Use a gentle, fragrance-controlled shampoo appropriate for a greasy, flaky scalp; if he brings his medicated shampoo, follow its instructions and contact time.
- Apply with fingertips, not nails, using light circular movements; keep massage brief and gentle, avoiding the most inflamed areas.
- Control water temperature (lukewarm, not hot) and rinse thoroughly.
- Avoid overlapping strong actives (e.g. do not add a strong exfoliant on top of an unknown medicated shampoo).
- Advise against scratching and explain that 'scrubbing it off' removes scale temporarily but can aggravate the underlying inflammation.
Rationale: the goal is to cleanse and soothe without disrupting the skin barrier or provoking a flare.
3. What aftercare and referral advice would you give, and what would make you stop and refer immediately?
Read the worked answer
Aftercare advice:
- Continue the medicated shampoo as directed by the pharmacy/GP; use a gentle maintenance shampoo between treatments.
- Wash after sweating; avoid very hot water and harsh styling products near the scalp.
- Do not scratch; if itching is severe, see the pharmacist/GP rather than self-treating with multiple products.
- Book a follow-up to monitor; note that the condition often recurs seasonally.
Stop and refer immediately if you see:
- Pustules, weeping, crusting or spreading redness (possible infection).
- Open sores or broken skin from scratching.
- Sudden hair loss, patchy loss or scarring.
- Severe pain, swelling or systemic symptoms.
- No improvement or worsening despite appropriate treatment.
