Dandruff is a common condition characterised by the flaking and scaling of the skin on the scalp, which may also be accompanied by a mild itch. It can be difficult for people to distinguish between dry scalp and dandruff, as they have a very similar appearance, however dandruff flakes are often larger and more greasy than the smaller flakes of dry scalp.
The exact cause of dandruff is unclear but various factors such as stress, hormones, change in season (particularly as we enter the winter months), medication, nutritional deficiencies and unhealthy lifestyle habits are all contributing factors to dandruff.
In the article Dr Seghers shares her treatment advice on the shampoos to use, active ingredients within the treatments and directions to get the very best results. She explains that many people find the treatment shampoos ineffective, however this can be a result of not leaving it on the scalp long enough before rinsing off, therefore not giving the product long enough to work. "The shampoo should be massaged onto the scalp and left to work for at least ten minutes before washing out," she advises.
Dr Seghers also explains about seborrheic dermatitis, which is a more severe form of dandruff. It has the same flaking, accompanied by a more aggressive itch and may also affect the skin on the rest of the body, particularly the face and the chest.
If there is no improvement after a month of treating dandruff with over-the-counter shampoos, if the itch is disturbing sleep (or becomes unbearable) or if your quality of life is being compromised, it may be time to consult with a dermatologist.
