Dry itchy scalp and hair loss can be a frustrating and embarrassing condition to deal with. It can cause constant itching, flaking, and redness on the scalp, as well as hair thinning and hair loss. The underlying causes of dry itchy scalp and hair loss are varied and can include scalp dryness and lack of moisture, scalp irritation and inflammation, scalp psoriasis and eczema, scalp fungal and bacterial infections, scalp seborrheic dermatitis and malassezia, scalp trauma and hair styling damage, genetics and hormonal imbalances. In order to effectively treat and prevent dry itchy scalp and hair loss, it’s essential to identify the underlying cause and take the appropriate steps to address it.
Causes of Dry Itchy Scalp and Hair Loss
One of the most common causes of dry itchy scalp and hair loss is a lack of moisture in the scalp. When the scalp becomes too dry, it can cause itching, flaking, and redness. This can also lead to hair thinning and hair loss as the hair shaft becomes more brittle and prone to breakage. The scalp requires a healthy balance of moisture to function properly, and a dry scalp can be caused by a number of factors such as harsh shampoos, cold and dry weather, low humidity, and using harsh styling products.

Another common cause of dry itchy scalp and hair loss is irritation and inflammation of the scalp. This can be caused by a number of factors such as chemical hair treatments, excessive use of hair styling products, and certain medical conditions. Irritation and inflammation can cause itching, redness, and soreness of the scalp, and can also lead to hair loss if left untreated.
Scalp Psoriasis and Eczema
Scalp psoriasis and eczema are chronic skin conditions that can cause dry itchy scalp and hair loss. These conditions are characterized by red, scaly patches on the scalp, and can cause itching, flaking, and soreness. These conditions can be difficult to treat, and often require a combination of medications and lifestyle changes to manage.
Scalp Fungal and Bacterial Infections
Scalp fungal and bacterial infections can also cause dry itchy scalp and hair loss. These infections are caused by overgrowth of yeast or bacteria on the scalp, and can lead to itching, flaking, and redness. Fungal and bacterial infections of the scalp can also cause hair loss if left untreated.

Scalp Seborrheic Dermatitis and Malassezia
Seborrheic dermatitis is a common condition that causes flaky, itchy skin, and is characterized by red, greasy, and scaly patches on the scalp. It is caused by an overgrowth of the yeast malassezia, which is present on the scalp in small amounts. It leads to excessive shedding of skin cells and formation of dandruff. Seborrheic dermatitis can cause hair loss and is often mistaken for dandruff.
Scalp Trauma and Hair Styling Damage
Physical damage to the scalp and hair can also cause dry itchy scalp and hair loss. Trauma to the scalp can be caused by tight braids, ponytails, or other hairstyles that pull on the hair.

Genetics and Hormonal
Hormonal imbalances and genetics can also play a role in causing dry itchy scalp and hair loss. Some medical conditions such as thyroid disorders, autoimmune diseases, and nutrient deficiencies can disrupt the normal functioning of the hair growth cycle, leading to hair thinning and hair loss. Genetic predisposition can also increase the risk of experiencing hair loss at an earlier age or experiencing hair loss at a greater rate.
