Selsun Dandruff Shampoo 2.5% is a dandruff shampoo that is a little more powerful than average brand shampoos. If you still have dandruff or suffer from scalp conditions after using other shampoos, Selsun Dandruff Shampoo may provide the solution you need.

The active ingredient in Selsun Dandruff Shampoo is selenium sulphide, which has a proven effect on dandruff.

Selenium sulphide targets dermatophytes, which are a type of fungus. Selenium sulphide also decreases the production of skin cells on the skins surface, and reduces the natural oil (sebum) that covers the skin.

Scaling skin conditions such as seborrhoeicc dermatitis are caused by fungi, which cause inflammation.

By killing the fungus that causes inflammation, selenium sulphide reduces dandruff, and alleviates the itchy and scaly symptoms associated with suborrhoeicc dermatitis.

Common causes of dandruff are the amount of grease on the scalp, and the growing of skin cells on the scalp. This shampoo reduces both of these, and so prevents dandruff.

Selsun Dandruff Shampoo is highly potent, and so should not be used every day. When used just a couple of times weekly, it can have a huge effect on dandruff.

Important information:

Avoid contact with eyes

This shampoo may cause discolouration in gold, silver, or metallic jewellery. It is advised that all jewellery is removed before using this shampoo.

This shampoo should not be used within two days of perming, tinting, or dying hair. Before performing any of these hair treatments, ensure all Selsun shampoo is rinsed out of the hair.

Selsun shampoo should not be used on:

Any opened wounds or broken skin

Children who are less than five years old

Any skin which has become inflamed



Only use this shampoo externally.

Shake the bottle well before using this shampoo.


To use, apply liberally to wet hair. Use enough shampoo to create a lather and apply this to hair. Leave the shampoo lather in the hair for three minutes, and then rinse it off.

Recommended treatment with Selsun shampoo is twice a week for two weeks, and then once a week for the following two weeks. Afterwards, the shampoo only need be used when necessary to control dandruff.



*Prescription medicines are supplied subject to a medical consultation at the discretion of a doctor.

Adults, including the elderly and children 5 years and over:

  • Apply the shampoo generously, twice a week for 2 weeks and then reduce the frequency of application to once a week for the subsequent 2 weeks. 
  • You can then use the shampoo as frequently as required in order to manage the condition.

Not everyone will experience side effects when they take medication, however if you do they can include:

  • Application of the shampoo to the scalp or skin might cause burning sensation or irritation. 
  • Hair discoloration might occur, though this can be minimized or avoided by washing the hair thoroughly after treatment.
  • Blistering can rarely occur, particularly if the shampoo is left in contact with the skin for a longer than recommended.
  • Dryness or oiliness of the scalp and hair including an increased amount of normal hair loss might occur.
  • Though not often, allergic reactions such as urticaria and rash have been reported.

If you are concerned about these effects, or if the product affects you in any other way, stop using it and talk to your doctor or pharmacist.
