Is Dandruff Genetic? How Your DNA Can Affect Your Skin and Hair

Ever had an itchy scalp and when you scratched it, white specks came falling off? Don’t panic, you aren’t going bald (most likely). A common scalp disease known as dandruff is characterized by the scalp’s exfoliation of dead skin cells in the form of white, gray, or yellowish flakes. Even while it isn’t harmful, the condition can be uncomfortable and cause irritation and discomfort. All ages can be affected by dandruff, and it can range in severity from minor to more severe cases.


Although the actual cause of dandruff is unknown, it is thought to be complex with genetics having a major part. There is evidence that dandruff tends to run in families, suggesting that the ailment may have a hereditary component. You could be more likely to get dandruff yourself if you have a family history of it.

Some people are genetically predisposed to dandruff and other skin conditions. Getting DNA testing for wellness might help you expect skin challenges, should they arise in the future.

Understanding Dandruff

The body’s response to fungus and other microbes on the scalp is also influenced by the immune system. The immune system’s reaction to these microbes can be influenced by genetic factors, which may have an impact on the possibility that dandruff will develop.


While genetics can contribute to the development of dandruff, other factors can exacerbate the problem or cause flare-ups. These elements might consist of hormonal adjustments, stress, certain skin care products, and environmental elements.

Symptoms and causes of dandruff

Dandruff is a common scalp condition with distinct symptoms and various underlying causes. The most common symptoms of dandruff include a flaky scalp in the presence of white or grayish flakes on the scalp and hair. These are dead skin cells coming off or shedding. Itching is also a common symptom and can lead to irritation and discomfort if not treated immediately. Some people also develop redness and swelling in the scalp if dandruff becomes more severe.

Causes of dandruff

A naturally occurring fungus on the scalp known as Malassezia is one of the root causes of dandruff. Malassezia feeds on the oils released by hair follicles, which in certain persons triggers an inflammatory reaction and an excessive exfoliation of dead skin cells (flakes).


While the fungus is typically the culprit, there are other factors that can cause dandruff as well. Seborrheic dermatitis is a more severe and persistent type of skin inflammation that has been linked to dandruff. It can affect places like the scalp, face, and upper chest that have a high density of oil glands. 


According to current theories, seborrheic dermatitis is caused by a Malassezia fungus overgrowth in combination with individual sensitivity and immune system responses. Is seborrheic dermatitis genetic? Quite possibly, just like dandruff and a myriad of other skin conditions.

Genetic Predisposition to Dandruff 

Different skin problems are significantly influenced by genetics. In fact, many skin conditions such as psoriasis, eczema, acne, wrinkles, and even cellulitis can be affected by your unique genetic makeup. 


Can dandruff be genetic? This skin and scalp condition can be influenced by genetics. Its severity, frequency, and even symptoms can be influenced by your DNA. However, there are many other factors that contribute to the formation of dandruff such as your environment, skin sensitivity, and other underlying conditions.


Genetics can play a role in dandruff development, making some individuals more prone to the condition if it runs in their family. Are you prone to dandruff due to genetics? Unlock LifeDNA’s DNA skincare report today. 

Treatments and Prevention

Anti-dandruff shampoos and other products with active chemicals like zinc pyrithione, salicylic acid, ketoconazole, or selenium sulfide are frequently used to treat dandruff. It is best to see a dermatologist for severe or persistent cases so they can make specific recommendations and rule out any underlying skin issues.


It’s important to remember that dandruff is a typical and usually benign condition. However, it is advised to see a dermatologist for a precise diagnosis and a customized treatment plan if symptoms increase, persists, or if there are other alarming signs including severe redness, open sores, or hair loss.
