Dry Scalp - Causes, Symptoms, and Treatment

Introduction:

Dryness of the skin usually happens when there is a lack of moisture. If the dryness happens in the scalp (the outer layer covering the head) then it is called dry scalp. Dry scalp is a common scalp condition that can cause discomfort and social embarrassment. The main cause of dry scalp is the lack of moisture. The natural moisture is not balanced and causes an itchy and flaky scalp. Home remedies are mostly tried by everyone and in minor cases the condition might improve.

What Is a Scalp and What Are Its Layers?

The scalp is composed of soft tissue layers that cover the skull. It is an anatomic region bordered anteriorly by the human face and laterally and posteriorly by the neck. It extends from the superior nuchal lines and occipital turbulences to the supraorbital foramen.

The scalp has five layers. The first three layers are closely bound together.

• The skin contains numerous hair follicles and sebaceous glands.

• Dense connective tissue connects the skin to epicranial aponeurosis. It is well vascularized and has a good nerve supply.

• Epicranial Aponeurosis is a thin, tendon-like structure that connects the scalp muscles.

• Loose Areolar Connective Tissue is a thin connective tissue layer that separates the periosteum of the skull from the epicranial aponeurosis.

• The periosteum is the front layer of the skull bones.

What Can Be the Reasons for Dry Scalp?

• Repeated Washing: This can cause the removal of natural oils in the scalp. This causes the scalp to be dry and brittle. The hair wash is done according to the texture of the hair.

• Usage of Harsh Hair Products: The scalp becomes red and starts itching on harsh chemicals. The flakes, after washing, could be contact dermatitis.

• Weather Changes: Cold weather dries out the skin all over the body, including the scalp. Blasting the heat can also cause drying.

• Dandruff: Dandruff can seem like the result of a dry scalp, but it can happen for many reasons, including a yeast-like fungus that feeds on the oils in the scalp. Dandruff is a symptom of a skin condition known as seborrheic dermatitis; it is eczema. This causes redness on the scalp, itching, and flaking on areas of skin, especially where there are lots of sebaceous glands.

• Eczema: Eczema is a skin condition that leaves the scalp dry, red, itchy, and cracked.

• Allergies: It often runs in families, so if one or both of the parents have eczema, the chances are high for the kids to have it. Soap, detergent, stress, and changes in the weather can cause dry eczema patches to form on the scalp. One may also have dryness on the hands, elbows, face, and the backs of the knees.

• Scalp Psoriasis: In psoriasis, the immune system makes the skin cells multiply faster than usual. These cells build up on the skin's surface and create dry, itchy patches.

• Atopic Dermatitis: Atopic dermatitis is a common form of eczema. In children, atopic dermatitis can cause dry, itchy rashes anywhere on the body. The individuals have dehydrated and easily irritated scalp.

• Contact Dermatitis: Contact dermatitis, another form of eczema, happens when the skin has an allergic reaction to something it comes into contact with. Hair care products, hair dye, and hair accessories can all lead to contact dermatitis on the scalp. Contact dermatitis can cause itching and burning.

How To Manage and Treat This Condition?

• Drink plenty of water.

• Get enough sleep.

• Avoid caffeine and alcohol. This can dry out the skin.

• Avoid specific heat sources, such as central heating and log fires.

• Do not use harsh hair products and shampoos.

Sometimes the management can also need corticosteroids. A person with a dry scalp will experience itching and flaking of the skin. Many dry scalp cases resolve independently with a good lifestyle and healthy diet. A dry scalp can be a symptom of an underlying skin condition or disease.

Some of the preventive measures are listed below:

• Regular Washing with Gentle Shampoos: Use a gentle, moisturizing shampoo free of harsh chemicals, sulfates, and alcohol. Avoid washing the hair too frequently, as this can strip natural oils.

• Stress Management: Manage stress through activities like exercise, meditation, or yoga, as stress can contribute to scalp issues.

• Proper Rinsing: Thoroughly rinse out all shampoo and conditioner to prevent residue buildup, which can contribute to dryness.

• Home Remedies:

  • Natural Oils: Apply natural oils, such as coconut oil or olive oil, to the scalp for extra moisture. Leave on for at least 30 minutes before washing out.

  • Aloe Vera: Apply fresh aloe vera gel before rinsing the scalp.
