Dandruff won’t go away? A doctor warns it could worsen without shampoos containing these essential anti-fungal and exfoliating ingredients.
Doctor Warns Dandruff May Worsen Without the Right Shampoo
A medical expert is sounding the alarm for Canadians dealing with persistent dandruff: your shampoo might be making it worse.
Dr. Simi Adedeji, a practicing physician, recently shared expert advice on scalp health, stating that many over-the-counter shampoos lack the essential ingredients needed to combat the root cause of dandruff. Her guidance arrives amid growing concern over self-managed scalp issues across British Columbia and beyond.
The Cause Behind the Flakes
Dandruff, while often dismissed as a cosmetic nuisance, is actually caused by Malassezia, an oil-loving yeast that thrives on the scalp. According to Dr. Adedeji, when this yeast breaks down natural oils on the scalp, it can lead to inflammation, dryness, and the signature white or grey flakes.
Contrary to common belief, dandruff is not linked to poor hygiene. However, factors like stress and colder climates—common in Canada—can worsen symptoms.
The Doctor’s Prescription for Relief
Dr. Adedeji urges those experiencing chronic dandruff to check the ingredients in their current shampoo. If key anti-fungal or exfoliating agents are missing, symptoms may persist—or even intensify.
Her top recommendations include:
- Ketoconazole: Slows yeast growth and treats fungal scalp infections.
- Selenium Sulfide: Controls yeast levels and reduces skin shedding.
- Coal Tar: Breaks up flakes, with anti-fungal and anti-inflammatory properties.
- Salicylic Acid: Loosens thick scales, helping them wash away easily.
These ingredients are all proven treatments supported by both the NHS and the Cleveland Clinic, with anti-fungal, antimicrobial, and keratolytic properties.
When to See a GP
Dr. Adedeji suggests trying a shampoo with the above ingredients for at least one month. If symptoms persist—such as ongoing itching, redness, or scaling—it’s time to consult a general practitioner.
The NHS advises medical evaluation if you’ve used anti-dandruff treatments without improvement, or if dandruff spreads beyond the scalp.
How to Choose the Right Shampoo
Choosing an effective shampoo means more than picking a familiar brand. Dr. Adedeji encourages reading labels and seeking formulations that explicitly list at least one of the active ingredients mentioned. Some medicated shampoos may be available over the counter, while others may require a prescription in Canada.
With proper treatment, most cases of dandruff can be managed effectively at home. However, timely intervention is key to preventing more severe scalp conditions like seborrheic dermatitis.
