What Causes Dandruff And Hair Loss

Dandruff and hair loss can have various causes, and sometimes they can occur together due to overlapping factors. Here are some common causes for each condition:


  1. Seborrheic dermatitis: This is a common condition characterized by an overgrowth of yeast on the scalp, leading to inflammation, flaking, and dandruff.
  2. Dry skin: Dry scalp can result in flaking and dandruff. It can be caused by cold weather, low humidity, or excessive use of harsh hair products.
  3. Sensitivity to hair care products: Certain hair care products, including shampoos, conditioners, or styling products, can irritate the scalp and lead to dandruff.
  4. Malassezia yeast: An overgrowth of the Malassezia yeast on the scalp can contribute to dandruff. This yeast is naturally present on the scalp, but an overgrowth can cause irritation and flaking.
  5. Poor hygiene: Infrequent shampooing or inadequate cleansing of the scalp can contribute to dandruff.

History behind dandruff

Concerning what is the cause of dandruff, the exact historical origins of dandruff are not well-documented, as the condition has likely existed for centuries. However, references to scalp conditions resembling dandruff can be found in ancient texts and medical literature.

In ancient Egypt, medical papyri dating back to around 1550 BC mention treatments for scalp conditions that may have included dandruff. These texts describe remedies involving plant extracts, oils, and ointments that were applied to the scalp to alleviate itching and flaking.

Throughout history, dandruff and other scalp conditions were often attributed to imbalances in bodily humors or considered signs of poor hygiene. Traditional treatments involved a range of herbal remedies, oils, and poultices applied to the scalp to soothe and moisturize the skin.

It wasn’t until the late 19th and early 20th centuries that scientific research and understanding of dandruff began to emerge. In the 1870s, a French scientist named Louis-Anne-Jean Brocq described the presence of specific yeast called Malassezia in individuals with dandruff. This discovery laid the foundation for later research on the role of Malassezia in dandruff.

Today, dandruff is recognized as a common scalp condition primarily caused by factors such as seborrheic dermatitis, dry scalp, Malassezia yeast overgrowth, and sensitivity to hair care products. Extensive research has been conducted to develop effective anti-dandruff treatments, including specialized shampoos and topical medications targeting the underlying causes and symptoms of dandruff.

While the understanding concerning what is the cause of dandruff and treatment of dandruff have significantly advanced over time, it remains a prevalent and manageable condition that continues to be a subject of scientific interest and ongoing research.

Hair loss:

  1. Androgenetic alopecia: This is a hereditary condition commonly known as male or female pattern baldness. It is characterized by a gradual thinning of hair over time.
  2. Telogen effluvium: Hair loss can occur as a result of a significant physical or emotional stressor, such as illness, surgery, childbirth, or extreme weight loss. This condition typically causes temporary hair shedding.
  3. Alopecia areata: This autoimmune condition causes patchy hair loss and occurs when the immune system mistakenly attacks the hair follicles.
  4. Scalp conditions: Certain scalp conditions, including seborrheic dermatitis, psoriasis, or fungal infections, can contribute to hair loss if left untreated.
  5. Hormonal changes: Hormonal imbalances, such as those occurring during pregnancy, childbirth, menopause, or thyroid disorders, can lead to hair loss.
  6. Nutritional deficiencies: Inadequate intake of essential nutrients, particularly iron, zinc, biotin, and vitamins D and E, can impact hair health and contribute to hair loss.

It’s important to note that these are general causes, and individual cases may vary. If you are experiencing persistent or excessive dandruff or hair loss, it is recommended to consult a dermatologist or a healthcare professional who can evaluate your specific condition, provide a proper diagnosis, and recommend appropriate treatment options.

History behind hair loss

Concerning what is the cause of hair loss, also known as alopecia, has been a concern for humans throughout history. Here is a brief overview of the historical understanding and treatment of hair loss:

Ancient times: Hair loss has been referenced in ancient texts and historical records. In ancient Egypt, there are depictions of men and women wearing wigs to conceal their hair loss. Ancient Greek and Roman texts also mention various remedies and potions to combat hair loss, often using ingredients like onion, honey, and herbs.

Middle Ages: During the Middle Ages, hair loss was often associated with aging or diseases like syphilis. Wig-making became a common practice, and wigs were worn by both men and women to cover baldness.

18th and 19th centuries: Medical understanding of hair loss began to emerge. In the 18th century, the French physician Jean Astruc proposed that hair loss could be caused by a specific type of inflammation. Treatments during this time often involved topical applications of various substances, such as oils, herbal remedies, and tonics.

20th century: Advances in medical knowledge led to the development of more effective treatments for hair loss. In the 1930s, the first hair transplant procedure was performed. In the 1950s, the use of synthetic drugs like minoxidil and corticosteroids gained popularity for treating hair loss.

Recent years: With advancements in medical technology and understanding regarding what is the cause of hair loss, various treatment options for hair loss have become available. These include hair transplant surgery, medications like finasteride, laser therapy, and scalp micro pigmentation.
