There are several connections between an itchy scalp and hair loss, including the use of harsh shampoos, ringworm, heat, tension, and psoriasis. These problems can also be the result of stress, too much salt in the diet, a lack of iron in the diet, or chemotherapy. A woman who has recently given birth may also experience hair loss and itchy scalp. Yeast infections of the scalp, aggravated by excessive amounts of sugar and dairy in the diet, can also lead to this condition.
An itchy scalp and hair that fall out can be caused by shampoo that is too harsh. These types of cleansers often cause scalp infections by damaging the follicles. One of the most common types of infections is known as folliculitis. With this condition, small pimples usually start to appear around the hair follicles and, if the condition is severe, they turn into boils. Antibiotics are needed to treat this problem; If treatment is not used, the result is usually scarring and permanent hair loss.
Too much heat can cause itchy scalp and hair loss, as can too much tension. Problems with hair tension are often seen in people of African descent who braid their hair tightly. This type of tension and pulling can cause irritation to the scalp and often destroy the hair roots. Identifying the problem early, taking steps to reduce pulling, and soothing the scalp will often prevent permanent damage.
Psoriasis is a very common condition in which red lesions appear on a person's scalp as a result of skin cells being replaced too quickly. This problem is not contagious and is often treated with special shampoos that contain zinc pyrithione. Herbal supplements, such as avocado or birch oil, can also help reduce itching, cure psoriasis, and prevent hair loss.
Ringworm appears as red spots on itchy skin. It is a fungal infection and, when localized to the head, it can cause itching and hair loss. This problem is highly contagious, but can usually be fixed with over-the-counter medications. However, if the yeast infection is severe, a prescription may be necessary.
Problems in a person's diet can also lead to itchy scalp and hair loss. This can be caused if a person does not eat enough protein or enough foods with iron. Although the subject is debated by many, some people believe that too much salt can suffocate and kill hair follicles. An excessive amount of sugar or dairy can feed yeast on the scalp, and this can cause dermatitis and dry skin that also leads to these symptoms.
Genetics, cancer treatments, stress, and childbirth are common reasons for these symptoms. Some can lead to permanent or long-term hair loss, while others are only temporary problems. Many times, the cause of the itchiness is the cause of hair loss, so identifying the exact problem often plays a key role in growing hair back.
