Why Do People Get Dandruff
Flaking and itchiness are common indicators that a person has dandruff and dry scalp. Too much oil on the scalp causes excess build up. The buildup then becomes dandruff and would soon shed in flakes.

While dandruff can be annoying and embarrassing, it usually doesn’t indicate a more serious health issue. People get dandruff simply because of an unhealthy scalp condition[1]. These are the most common conditions that put you in higher risk of getting dandruff:
- Oily skin – People with oily skin are most likely to have dandruff. Oily skin results to excess sebum production. If left untreated, it can become red, start to turn into white or yellow flakes, and become irritated. Seborrheic dermatitis is a more severe version of dandruff caused by oily scalp.
- Dry skin – A dry scalp lacks moisture and tends to flake and itch. Flakes from dry skin are smaller. The redness or inflammation is unlikely.
- When you don’t shampoo and brush regularly – If you don’t regularly wash your hair, the natural oils and skin cells from your scalp may build up. This increases the risk of dandruff. Brushing the hair reduces the risk of dandruff because it helps in the normal shedding of your skin.
- Yeast-like fungus – Malassezia is a dandruff causing fungi that lives on the scalp of many adults. Unfortunately, in some people, this yeast-like fungus irritates the scalp. It may cause more skin cells to grow and when these cells die and fall off, they appear like flakes in your hair. It is not known why Malassezia irritates some scalps.
- Sensitivity to hair care products – Sometimes sensitivities to certain ingredients in hair care products or hair dyes can cause a red, itchy, scaly scalp.
- Excessive use of hair products – too much use of hair products such as gels, waxes, and hair sprays can increase hair buildup and cause dandruff. These products also cause the scalp’s natural pH to be out of balance.
Most of the time dandruff isn’t complicated and you won’t need to consult a doctor. However, if there are signs of infection and swelling or if dandruff severely persists after a month of home treatment, seek medical help.
How Dandruff Shampoo Works
If your scalp is itchy and flaky, you may get some relief by using shampoos formulated to treat dandruff. Even the act of washing and brushing the hair can help remove old skin flakes. If you want to learn more about different hair tools like brushes and combs, check out the next article.
The approach to treating dandruff depends on the patient’s age and the severity of the condition. Generally, dandruff shampoos[2] work to cleanse and nourish your hair while fighting the causes of dandruff such as dry scalp.
For children or older individuals a gentler cleansing method is often used to get rid of dandruff. Children and elderly have skin that’s more sensitive than usual so they need gentle hair cleansers. For adults, there are shampoos and deep cleansing treatments made with ingredients that can keep dandruff away. These treatments may contain chemicals that effectively get rid of flakes and bacteria-causing dandruff.

Using dandruff shampoos have many benefits. If you find the right one, you may end up with great results. Dandruff shampoo works by washing the hair and scalp to get rid of dirt and excess oil buildup. Dandruff shampoos remove many pollutants from your hair and scalp when used correctly. These types of shampoos also help clean buildup caused by styling products.
As the dandruff shampoo is massaged into the scalp and through the hair, it breaks up and loosens existing flakes. Much of the existing external dandruff is washed away when the shampoo is rinsed out. This decreases the appearance of flakes.
Many dandruff shampoo products also offer nutrient-rich formulas that moisturize the scalp and keep hair healthy. The majority of dandruff shampoos use active ingredients to balance the scalp’s oils. This is what may treat dandruff directly to reduce the reproduction of excess oils or decrease the yeast production.
Best Dandruff Shampoo
The best dandruff shampoo should work to cleanse and nourish your hair while its active ingredients decrease the likeliness of dandruff from occurring again. It should contain ingredients proven to treat dandruff and dry scalp[3].
Ingredients That Help Get Rid of Dandruff
There are many natural and chemical based ingredients that target dandruff specifically. Some dandruff shampoos carry only one of these ingredients while others contain a mixture of one or more. Some ingredients are gentle on hair while others can be drying. These are the ingredients to look for when you want to know which dandruff shampoo actually works:
Tea Tree Oil
Tea tree oil is an essential oil derived from an Australian native plant with the same name. Many dandruff shampoos include this ingredient. It has long been used as an antibiotic and antiseptic ingredient that is known to fight bacteria. Tea tree oil is also known to have anti-fungal properties. It can battle fungi like the Malassezia to treat dandruff. This oil does this without drying your scalp.
Ketoconazole
Ketoconazole is an effective antifungal medicine. Shampoos containing this ingredient treat scalp infections including yeasts. Over-the-counter ketoconazole shampoo[4] controls scalp flaking, scaling, and itching caused by dandruff.
Selenium Sulfide
Selenium sulfide is a medication that treats dandruff. It is found in many anti-dandruff shampoos since it reduces the production of natural oils in the scalp. Reduced production can result to less flakes. Selenium sulfide also lessens itching, flaking, irritation, and redness of the scalp.

Coal Tar
Coal tar is a natural anti-fungal agent. It causes the skin to shed dead cells from its top layer and slow down the growth of skin cells to get rid of flakes. This decreases the scaling and dryness of your scalp. Coal tar can also decrease itchiness and other irritations caused by dandruff.
Salicylic Acids
Salicylic acid helps the scalp remove dead skin cells that may have accumulated on the scalp. They do not slow down the reproduction of skin cells. It loosens and softens scaly skin, making it easier for the shampoo’s cleansing properties to wash it away.
Zinc Pyrithione Or Pyrithione Zinc
Zinc pyrithione is a complex formulation of zinc that inhibits the division of fungal cells and bacterial cell division to help in treating dandruff. It first removes the visible symptoms of dandruff such as flakes or inflammation. Then it fights the underlying cause of dandruff for complete relief and prevents the symptoms from reappearing.
How Dandruff Shampoos are Used
The best way to use dandruff shampoo is to select a shampoo containing one of the ingredients above. You must also follow the instructions when using the shampoo for best results.
When you find dandruff shampoo that works for you[5], using it the proper way is necessary for it to be effective. For the treatment of dandruff, follow the product label’s instructions, or use as directed by your doctor. Make sure you read the instructions that come with the shampoo before using it to check if it’s suitable for you and see how often it should be applied.
Most shampoos have specific instructions for their use but generally, you may follow these steps:
- Some brands require shaking the bottle before use. Check your product package to see if your brand needs to be shaken.
- Wet scalp and hair thoroughly. Some dandruff shampoos require application on dry hair only so take note of that as well.
- Apply a generous amount of dandruff shampoo on your scalp and massage into a lather. Run your fingers through the length of your hair so that the shampoo covers all areas of your hair.
- Leave shampoo on the scalp for three to five minutes before rinsing. Leaving the shampoo on hair give the ingredients time to work.
You may try dandruff shampoos for a month to see if the state of your scalp improves. You might need to try more than one type to find one that works for you. It may take time but when you get to the right one, it is worth it. You may be able to use the shampoo less when your symptoms improve, but your dandruff will probably come back if you stop using it completely. Regular use is still advised.

Castor oil contains Ricinoleic acid that has antimicrobial properties to kill bacteria that cause dandruff. Learn more about these and other essential oils you can use for your hair.

The acidity of apple cider vinegar changes the pH of your scalp, making it harder for the yeast to grow. This is a great anti-inflammatory and anti-bacterial aid. It is not only for treating the unpleasant itchiness and for flaking, but also in making sure that dandruff is less likely to occur again.
