Quick Answer — What is Selsun Suspension?

Selsun Suspension contains selenium sulphide 2.5% — a topical anti-Malassezia suspension licensed for dandruff, seborrhoeic dermatitis, and pityriasis versicolor. Apply to wet scalp, lather, leave on 2–5 minutes, then rinse thoroughly. Effective from the first wash. Do not get in eyes; rinse hands and avoid contact with jewellery. Slight medicinal odour and a small risk of hair discoloration in dyed or grey hair are the trade-offs versus ketoconazole shampoo.

What Selsun Suspension Treats

  • Dandruff (pityriasis capitis) — non-inflammatory white-grey scalp flaking driven by an inflammatory response to Malassezia yeast.
  • Seborrhoeic dermatitis of the scalp — inflammatory greasy yellow scale, often with itch and erythema.
  • Pityriasis (tinea) versicolor of the trunk — yeast-driven hypo- or hyperpigmented patches on the chest, back, and shoulders. Selenium sulphide is particularly effective for this indication and is often preferred over ketoconazole shampoo as a body wash.
  • Adjunct in scalp psoriasis — softens scale and reduces secondary Malassezia colonisation, alongside dedicated antipsoriatic treatment.

How Selsun Suspension Works

Selenium sulphide acts on the scalp through three concurrent mechanisms:

  1. Direct anti-yeast activity. Reduces colonisation by Malassezia furfur / globosa and impairs yeast cell wall function.
  2. Slows corneocyte turnover. Cytostatic effect on the epidermis — the hyperproliferating scalp produces fewer flakes per unit time.
  3. Sebostatic action. Reduces sebum production at the follicle, which removes part of the lipid substrate that Malassezia depends on.

Tinea versicolor short courseOnceOvernight (8–10 hours)Single application; repeat in 7 days

Shake the bottle well before each use — selenium sulphide is a suspension and the active settles. Wet the scalp thoroughly, dispense a teaspoon-sized amount onto the palm, and massage into the scalp for 30 seconds to build a lather. Leave the lather in contact for the full 2–5 minute window — short contact is the most common reason for failure. Rinse with running water until clear. Wash hands afterwards.

Avoid contact with eyes, broken skin, jewellery, and dyed hair freshly bleached. Selenium sulphide can sting irritated skin and tarnish silver, gold-plate, and certain dyed hair shades (particularly grey, blonde, and recently lightened or bleached hair — temporary discoloration to a yellow-green tint). Remove jewellery before washing. If accidental eye contact occurs, irrigate with running water for 15 minutes and seek medical attention if irritation persists.

Side Effects of Selsun Suspension

Common (1–10%): mild scalp irritation, dryness, and transient hair texture change (rougher feel after rinsing — a conditioner offsets this); slight medicinal odour during application.

Uncommon (<1%): hair discoloration in dyed, grey, or blonde hair (yellow-green tint, generally transient and washes out within a few normal shampoos); excess oiliness or dryness; folliculitis; allergic contact dermatitis (red, itchy weeping scalp — discontinue).

Zeldzaam: nail discoloration if used on the body and the suspension is left under fingernails; hair shaft damage with long-overcontact times.

Systemic side effects from topical use are vanishingly rare. Selenium absorption through intact scalp skin during a 2–5 minute exposure is negligible.

Both work. Pick selenium sulphide if you also have or worry about pityriasis versicolor on the body, or want a different mechanism for refractory dandruff. Pick ketoconazole 2% shampoo if you have significant scalp inflammation and itch (better suited to that profile) or if you have light dyed hair. Many users with severe seborrhoeic dermatitis alternate the two between wash days.

Geneesmiddelinteracties

No clinically relevant systemic drug interactions. Topical exposure is too low to interact with oral medications. Avoid same-day use with coal tar shampoo (alternate on different days). Do not combine with topical hydrocortisone in the same wash unless your dermatologist has set out an alternation schedule.

Pregnancy, Breastfeeding, and Children

Zwangerschap en borstvoeding. No reported teratogenic concern. Topical exposure in a rinse-off product is negligible and the suspension has been used for decades by pregnant women. Avoid applying to broken skin or to the nipple if breastfeeding.

Children. Used from age 5 upwards under paediatric supervision; not generally recommended in infants. Cradle cap in babies should be discussed with a paediatrician.

Opslag

Store Selsun Suspension below 25°C in the original bottle, tightly capped. Shake before each use. Keep out of reach of children and pets. Discard after the printed expiry date.

Veelgestelde vragen

Will Selsun Suspension lighten my hair colour?

Yes, occasionally — particularly on grey, blonde, or freshly dyed hair, where it can produce a transient yellow-green tint. Normal shampoos wash this out within a few washes. If you have a recent expensive colour, wait 7 days before the first medicated wash and consider ketoconazole 2% shampoo as a colour-friendlier alternative.

How fast does Selsun Suspension work?

Many patients see less itch after the first wash. Visible reduction in flaking takes 1–2 weeks. For pityriasis versicolor on the body, repigmentation of the affected patches can take several months — the active infection is gone within 1–2 weeks but the colour change persists until normal melanin production resumes.

Why does it smell?

Selenium compounds have a faint sulphur odour. The smell is from the active itself, not a perfume. It is most noticeable during application and largely gone after rinsing. Hair styling products mask any residual smell once dry.

Can I use Selsun Suspension for tinea versicolor on the body?

Yes — this is one of its best indications. Apply to wet skin (chest, back, shoulders), lather, leave for 5–10 minutes, then rinse. Daily for 7 days, then repeat at 1 month if needed. For widespread or stubborn cases, oral antifungal therapy (fluconazole single-dose or itraconazole short course) may be needed.

Can I leave Selsun Suspension on overnight?

Generally no — overnight contact substantially increases the risk of scalp irritation, hair shaft damage, and discoloration. The exception is the single-application overnight protocol some dermatologists use for stubborn pityriasis versicolor on the body. For the scalp, never leave on longer than 5 minutes.

Why does it tarnish my jewellery?

Sulphide compounds react with silver, gold-plate, and some other metals to form sulphide tarnish. Remove all jewellery (rings, earrings, chains) before washing. Tarnish on real silver can be reversed with a polishing cloth.

Is Selsun Suspension safe in pregnancy?

Compatible. Topical absorption from a rinse-off scalp product is negligible and the suspension has been widely used in pregnancy without reported harm. Avoid applying to broken skin and follow normal directions.

Can I combine Selsun Suspension with ketoconazole shampoo?

Yes — alternating the two between wash days is a standard regimen for severe or refractory dandruff and seborrhoeic dermatitis. They have different mechanisms so the combination is additive, not redundant. Do not mix them in the same wash.

What if my dandruff is not improving?

Check the basics — full 2–5 minute contact, 2–3× weekly induction. After 4–6 weeks of correct use without improvement, consider scalp psoriasis, contact dermatitis, or tinea capitis as differentials and consult a dermatologist. Oral antifungal therapy (Nizral or itraconazole) is sometimes needed for refractory disease.

Is selenium sulphide poisonous if accidentally swallowed?

Small accidental amounts during a wash are unlikely to cause serious harm but can cause GI upset (nausea, vomiting). Significant ingestion needs urgent medical attention — call your local poison centre or attend A&E. Keep the bottle out of reach of children.

Medisch disclaimer. This page is for general educational purposes only and is not a substitute for personalised advice from a qualified clinician. Persistent itchy red scalp, scaling that does not respond to medicated shampoo within 4–6 weeks, hair loss, or extension of the rash to the face or trunk should be assessed by a dermatologist. Other conditions can mimic dandruff: scalp psoriasis, contact dermatitis, tinea capitis, lichen planus, and discoid lupus. New-onset severe dandruff in immunocompromised patients (HIV, chemotherapy, transplant) deserves prompt assessment.
