Why do you still have dandruff after washing your hair? This is a question both men and women from all age groups wonder about when dealing with recurring dandruff. The thing is, there are a lot of reasons why this issue may continuously occur. As we age, the oils in our skin break down. The ones that build up on the scalp can cause excess dryness and flaking. It is a common misconception that dandruff persists only because of a lack of hygiene practices. Washing your hair alone would not get rid of nor prevent it. The bottom line is that there are other factors that cause the persistent appearance of dandruff even after washing your hair regularly. In this article, we will provide you with more insight into those factors.


Your dandruff can be caused by a fungus

If you have dandruff, it’s likely caused by a fungus. This type of bacteria is common and can be treated with an anti-fungal shampoo (like Head & Shoulders). If you’re unsure what the cause is, see your doctor or dermatologist for advice on treating it.

Your dandruff can be caused by sensitivity to certain hair products

If you’re having dandruff, you might have sensitivity to particular hair products. Your scalp may be sensitive to certain ingredients in the shampoo or conditioner you use.
If this happens, try using a different shampoo or conditioner that doesn’t contain those particular ingredients.

Your dandruff may be genetic

Apart from being caused by a fungus, dandruff is most likely also genetic. If you have dandruff, it’s important to figure out what triggers it so that you can avoid those triggers and get rid of the flakes for good.
Have you ever wondered why some people seem to get dandruff more often than others? Or why are some people prone to flaking more than most people? There’s an answer here: genetics play a role!
Your genes determine how much sebum (the oil that protects your skin) you produce on your scalp when hair grows, which then determines whether or not there will be an excessive amount of oil present on your head when shampooing etcetera.

It’s essential to wash your hair regularly to prevent dandruff

• Wash your hair with a mild shampoo.
• Use a conditioner to moisturize your hair and keep it moisturized throughout the day.
• Dandruff shampoos are available in different strengths, so look for one that works for your scalp and dandruff issues. They can help treat both scalp irritation and flaking skin if used regularly (three or four times a week).
• If you want to prevent future dandruff, try an anti-dandruff shampoo—these contain ingredients like sulfur or salicylic acid which kill the fungus that causes dandruff symptoms on the skin surface of our scalps by penetrating deep into the pores where it thrives!


Many factors can contribute to your dandruff condition and you must work with a doctor or dermatologist to properly identify what is causing it. Washing your hair alone may not aid your persistent dandruff. It is recommended that you wash your hair at least twice a week and more often if you have oily or wavy hair, then make sure to use conditioner. Try to rinse it out immediately afterward so that the conditioner doesn’t sit there too long before being washed away with more water.
