About Dermax Shampoo 

Dermax Therapeutic Shampoo is a treatment for scaly scalp conditions such as dandruff or seborrhoeic dermatitis. Dermax Shampoo uses benzalkonium chloride, which works by loosening skin flakes from the scalp and lifting them from the hair. 

Benzalkonium chloride also acts as an antiseptic, allowing the shampoo to help keep the scalp free of infection. In particular, this ingredient helps combat the yeast that makes scaly scalp conditions worse.

Dermax is designed to be easy to use and simple to add to your existing shower routine.


Some patients may find that Dermax Shampoo isn’t as effective at treating their symptoms. Here at Simple Online Pharmacy, we have a number of alternatives available, including;

Practical Tips

Dandruff and scaly scalp conditions can be difficult to live with. Follow these simple tips to make sure your scalp is protected;

Don’t scratch - dandruff can be itchy, especially when flakes are just starting to separate from the scalp. Scratching these itchy spots can lead to further damage to the scalp. Instead, try tapping the affected area. This activates the same nerve ending as scratching while producing much less damage.

Wash your hair less - in some cases, excess washing of the scalp can strip the protective layer of oils your skin produces. This can lead to skin drying out further, creating more problems. Rather than washing your hair daily, try to space it out to every other day, or even every two or three. If you find your hair looks greasy, try using a dry shampoo. These can help reduce the appearance of oils in hair, without causing as much damage.

How To Use Dermax Shampoo

Wet the hair thoroughly. Apply a small amount of shampoo to your hands roughly the size of a fifty-pence piece for shorter hair, or more as required. Massage to produce a rich lather.

Massage into the scalp with the tips of your fingers. Once applied, remove as much lather as possible with your hands. This step is important, as it will help lift the scale from the scalp.
