What Causes A Dry, Itchy Scalp?

A dry scalp is more common than you might realise and certainly nothing to be ashamed of. We understand that the scratching, flaking skin, and discomfort of a dry scalp can become tiring, so we’re here to help. Keep reading as we explain the causes of itchy scalp and talk you through a range of dry scalp treatments and our best natural hair shampoo and conditioner for a healthier, happier scalp. 

What causes a dry scalp? 

A dry scalp can be caused by a number of factors, including medical conditions, hair products, and environmental changes.  

While an itchy scalp may not indicate anything severe, knowing the cause can help determine how to treat and prevent it. Here are a few potential causes of dry scalp: 

1. Dandruff 

Dandruff is the most common cause of an itchy scalp. It triggers itching, flaking, scaling, and red skin. 

2. Contact dermatitis 

If your dry scalp is itchy but you don’t have dandruff, contact dermatitis could be the cause.  

Contact dermatitis is an allergic reaction to certain hair products, such as shampoo, conditioner, and hair dye. Common ingredients, including Parabens and PDD (often used in hair dye), can cause irritation to the scalp, resulting in unwanted redness and itchiness.  

3. Over-washing 

Washing your hair too often can strip your scalp of the natural oils it needs to stay hydrated, causing a very dry scalp 

If you’re washing your hair more than 3 times a week and are experiencing unwanted itchiness, it’s probably time to rethink your washing schedule. 

4. Weather changes 

When temperatures drop in the colder months, so does the humidity in the air. This naturally dries out the skin all over, including your scalp. When you turn the heating on to try and warm up, it has the same drying effect. 

5. Medical conditions 

A dry scalp could indicate an underlying condition, such as: 

  • Anxiety disorder 
  • Shingles 
  • Head lice 
  • Allergies 
  • Psoriasis 
  • Alopecia 

We recommend speaking to your GP about these. 

How to treat dry scalp 

The best dry scalp treatments include making some changes to your haircare routine and lifestyle to properly treat the irritation. 

Step 1: Change your products 

Choosing gentle, natural hair products will help to soothe the scalp and calm irritation. Our Hydrating Shampoo is the best dry scalp shampoo as it uses moisturising Shea Butter and Coconut Extract to help nourish and condition the scalp. 

Pair this dry scalp shampoo with our Hydrating Conditioner for the best results. Free from sulphates, silicones and harsh chemicals, this natural conditioner is rich in Olive and Sesame Oils to nourish the scalp. 

Finally, introducing a leave-in treatment to your routine is a great way to replenish scalp moisture. Our Hydrating Treatment Hair Oil harnesses a hydrating concentration of Argan, Olive, and Jojoba Oils to restore lost hydration. 

After a few weeks of regular use, your scalp should feel less dry and much happier. 

Step 2: Wash gently  

Now that you’ve got the right products for your dry scalp, you need to use them efficiently. Frequent washing with hot water will only dry out your scalp, so it’s important to use lukewarm water to maintain the perfect moisture level. 

Gently massage in your dry scalp shampoo to form a lather. Then, wash it out thoroughly, as any leftover product will only cause irritation. Follow with conditioner for increased moisture. 

Try to wash your hair 2-3 times a week to avoid stripping the scalp of its natural oils. 

Step 3: Stay healthy and hydrated 

A simple dry scalp treatment is to eat well and drink more water. When your body is dehydrated, so is your skin. Drinking 6-8 glasses of water a day helps to replenish hydration levels and reduce dry, flaky skin. 

Incorporating key nutrients into your diet such as Zinc, Omega-3 fatty acids, and Vitamin A can also  help to support the maintenance and function of skin cells, blood circulation, and tissue growth and repair. Eating more eggs, fruit, vegetables, and oily fish is a great way to include these nutrients into your diet. 

If you are trying a product or ingredient for the first time, we always recommend a patch test first.
