How to Treat Dry Scalp: Tips for Treatment & Prevention

Having a dry scalp can be frustrating, uncomfortable and embarrassing for some. There are a variety of factors that can contribute towards a dry scalp, including cold weather, hot showers, harsh hair products, and poor diet. Our nutritionists share a number of ways you can improve a dry scalp, including dietary changes as well as some home remedies that can help.

What Causes Dry Scalp?

Dandruff

Dandruff is a common condition often mistaken for dry scalp. Both conditions cause flaking and itching, however dandruff is caused by the fungus Malassezia, which feeds on oils on the scalp. For treatment, nutritionists recommend trying antifungals, preferably natural ones like coconut tea tree oil.

Sometimes, the cause of a dry scalp is eczema or psoriasis. These are both caused by abnormal immune function. It is worth getting your scalp checked over by a doctor who can make an appropriate diagnosis.

What Food Should You Avoid for Dry Scalp & Dandruff

Maintaining a healthy scalp starts with your diet. Certain foods can exacerbate dryness and dandruff, so it's important to know what to avoid.

Sugary Foods

Foods high in sugar can trigger inflammation in the body, which may lead to a dry scalp. Try to limit your intake of sugary snacks, desserts, and beverages.

Processed Foods

Processed foods, including fast food, chips, and packaged snacks, often contain unhealthy fats and preservatives that can contribute to scalp dryness and dandruff.

Alcohol

Excessive alcohol consumption can dehydrate your body, including your scalp. This can lead to dryness and flakiness. Moderation is key to maintaining scalp health.

How to Treat Dry Scalp

Professional treatments

Glycolic acid and coal tar are used in professional treatments. Glycolic acid exfoliates, removes dead skin and promotes cell turnover. Coal tar reduces inflammation and itching. There are downsides to using these however, so it is preferable to improve the diet first.

Treatment at Home

Apple cider vinegar

Mix in equal parts water and apply to the scalp. Leave for a few minutes before rinsing. The acidity helps balance the scalp pH, reducing dryness and itching.
