10 Home Remedies for An Itchy Scalp That Actually Work (Backed by Science)

Having an itchy scalp is common for most people at some point in their lives. The itch sensation can occur due to multiple reasons, such as dandruff, dry skin, fungal infections and allergic responses. 

Persistent and uncontrollable itchiness can significantly disrupt one’s quality of life, and scratching the scalp can cause skin damage. Ongoing itchiness may indicate that something more is going on, such as an underlying medical condition or a scalp issue. 

To treat itchiness, on the market you’ll find both over-the-counter medicated shampoos, as well as natural remedies to help ease the sensation. 

In this article, we’ll dive into why exactly an itchy scalp occurs, as well as ten home remedies that you can try to deal with it effectively. 

What Causes an Itchy Scalp?

Identifying the root cause becomes essential before beginning treatment for an itchy scalp. 

The following are major causes of an itchy scalp:

1. Seborrheic dermatitis: This common skin condition is also known as ‘scalp eczema’. Commonly, this skin condition is often associated with an overgrowth of yeast known as Malassezia and elevated sebum production, which leads to inflammation and irritation. It is essential to recognise that this condition is not solely caused by a fungal infection, but rather by imbalances and loss of integrity in the skin barrier, resulting in a flaky, itchy, and inflamed scalp.

2. Scalp psoriasis: This condition causes itchy, scaly patches similar to those seen in eczema. It results from an immune reaction that speeds up skin cell production, leading to flaky, itchy, and thick patches of skin. An itchy scalp can occur with both conditions.

3. Fungal infections: A fungal infection can irritate the scalp, causing itchiness and redness. Ringworm of the scalp (also known as tinea capitis), as well as yeast and dermatophyte infections, can all cause inflammation and commonly grow in warm, humid environments.

4. Allergic reactions: An allergy to certain hair products and substances can irritate the scalp, inducing itching, as the body’s immune system overreacts to perceived dangers. 

5. Contact dermatitis is a common allergic condition that occurs due to skin reactions to certain irritants in shampoos, dyes, fragrances, and styling products.

6. Product buildup on the scalp triggers itchiness due to residues left behind from conditioners, gels, dry shampoos, and other substances. Hair products that fail to adhere correctly to poorly washed scalps can trap sebum and dead skin cells, leading to buildup and irritation. 

The correct remedy requires identifying the fundamental cause, which is likely a common condition listed above.

Further reasons for an itchy scalp do exist, but these cases require more extensive treatment and investigations. 

10 Quick Home Remedies for Itchy Scalp

• Apple Cider Vinegar Rinse

Apple cider vinegar has been shown to have antimicrobial and anti-inflammatory properties, which help fight fungal and bacterial causes of an itchy scalp. 

Apply diluted apple cider vinegar with water at a 1:1 to 1:4 ratio to your clean scalp after shampooing, then gently massage it in before allowing it to rest for 5–10 minutes. Complete the process by thoroughly rinsing with cool water, followed by using a lightweight conditioner to restore hydration to your hair. 

• Tea Tree Oil (Diluted)

The application of tea tree oil requires dilution with a carrier oil when treating scalp itchiness. The strong power of tea tree oil requires dilution because it can cause skin irritation in its pure form. However, it is an excellent fighter of fungal infections and helps to reduce inflammation when used correctly. 

The application method involves mixing 2-3 drops of tea tree oil with 1 tablespoon of carrier oil, such as coconut, almond, or jojoba oil. Apply the mixture to your scalp by gently massaging it for 15 to 30 minutes. Rinse, then wash your hair with shampoo and conditioner. 

• Aloe Vera Gel

The anti-inflammatory, moisturising and soothing properties of Aloe Vera gel make it very beneficial for treating an itchy scalp, as well as dandruff and seborrheic dermatitis. 

To use this remedy, apply 100% pure aloe vera gel (containing no added alcohol or fragrance) to your scalp and gently massage it in. Let it sit for 30–60 minutes, then wash it out with a mild shampoo. Apply it 2 to 3 times per week when needed.

• Coconut Oil Massage

People typically recognise coconut oil for its benefits in promoting hair growth. Additionally, the naturally saturated fat content in coconut oil helps provide relief from scalp irritation, flaking, and itching. 

To apply, heat the coconut oil until it becomes fluid and massage it into irritated, dry or itchy areas. Let it sit for 10–30 minutes, then wash your hair thoroughly with a mild shampoo to complete the process.

• Witch Hazel Scalp Toner

 A mixture of Witch hazel with a few drops of essential oils, including tea tree or lavender oils, creates a scalp toner that provides anti-inflammatory benefits to treat both itchy scalp conditions and soothe skin irritation. 

Before washing your hair, apply a small amount of witch hazel scalp toner to your scalp. Use your fingers to massage the solution into your skin while it penetrates. Let it sit for only a few minutes before rinsing thoroughly with a mild shampoo.

• Baking Soda Exfoliant

Baking soda functions as an organic exfoliant, easing scalp irritation and reducing dandruff. The substance removes dead skin cells and excess oil, and has been shown also to help fight fungal infections. It is essential to note that while baking soda is effective, using it at high concentrations or repeatedly can cause harm to the scalp due to its high pH level. 

To use baking soda safely, mix 1-2 tablespoons of baking soda with water, then apply it to the scalp while gently massaging or scrubbing. Rinse thoroughly and wash with a mild shampoo. 

• Neem Oil Treatment

The antifungal and anti-inflammatory properties in neem oil create an effective treatment for itchy scalp conditions. The active ingredient nimbidin in neem oil is beneficial for treating dermatitis and psoriasis of the scalp.

Begin scalp treatment with neem oil by combining it with coconut or jojoba oil, then apply it to the scalp. Allow the mixture to sit for 30-60 minutes before rinsing and washing thoroughly with a mild shampoo. The recommended number of applications is 2 to 3 times per week.

• Warm Olive Oil & Lemon

The combination of warm olive oil with lemon juice provides relief to an itchy scalp while possibly treating dandruff. Applying hot olive oil provides scalp massage benefits that enhance blood circulation and moisturization.

At the same time, the acidity of lemon juice helps normalise the scalp’s pH and potentially reduces symptoms of itching and dandruff.

To use, apply gently heated olive oil to your scalp and massage for a few minutes. A combination of fresh lemon juice and water, in a ratio of 1 tablespoon each, should be mixed with one tablespoon of oil and applied to the scalp. After rinsing with water, follow up with a thorough wash using a mild shampoo. 

• Onion juice 

Onion juice possesses both anti-inflammatory and antibacterial properties, which may reduce scalp itchiness, dandruff, and promote overall scalp health. The treatment is believed to boost blood flow, which may stimulate hair growth.

To maximise the effectiveness of applying onion juice to your scalp, gently massage the area to enhance absorption and stimulate blood circulation.

Apply the mixture to your scalp for 30 minutes to 1 hour, then rinse with a gentle shampoo. The treatment should be applied twice per week for 4 to 6 weeks to achieve optimal effects. The combination of onion juice with honey, coconut oil, olive oil, aloe vera gel, or tea tree oil drops provides additional antifungal benefits, enhancing the effectiveness of the treatment.

• Yoghurt mask

A yoghurt mask works well for itchy scalps as it cleans and moisturises the skin. The basic mask preparation involves mixing plain yoghurt with honey or lemon juice and applying it to the scalp for 20 to 30 minutes before washing it off.

For additional anti-inflammatory benefits, mix ¼ cup plain yoghurt with one tablespoon of honey or lemon juice and massage into the scalp. Let the mixture sit for 20-30 minutes, then rinse and wash thoroughly with a mild shampoo. The treatment combines itch-relief benefits with scalp nourishment.

Scalp-Friendly Habits

Alongside natural remedies, the following list presents essential habits for maintaining a healthy scalp:

1. For optimal results, hair washing should occur only 2 or 3 times per week. Proper washing frequency removes product buildup, oil, and debris without stripping the hair of its essential natural oils. 

2. Choosing the right shampoo and conditioner depends on your hair type and skin. For example, sensitive scalps require products typically free from harsher ingredients, such as sulfates.

3. The use of alcohol-containing products and other harsh ingredients should be avoided as they can cause dryness and irritation to the scalp. 

4. Using heat-styling tools on your hair should be limited, as heat both irritates the scalp and damages the hair. Heat protectant sprays should be applied before using heat-styling tools on the hair. 

5. Protect your scalp from sun damage by wearing a hat, which is especially important during peak sun hours. 

6. Scalp exfoliation requires using either an exfoliator, a scalp scrub or a brush to eliminate scalp accumulation. Once a week is recommended. 

7. Scalp massage stimulates blood circulation, which helps promote hair growth while also improving scalp health. 

8. To prevent the spread of infection, avoid sharing personal items such as brushes and combs. 

9. Brushing your hair frequently helps remove accumulations while reducing hair tangles.

10. Consuming a nutritious diet rich in vitamins and minerals, combined with drinking sufficient water, promotes healthy hair, skin, and overall well-being. 

When to See a Dermatologist 

While home remedies can be beneficial, sometimes they are just not enough. When home treatments fail to help despite regular and thorough application, it is essential to seek further medical advice, especially if you develop any of the following symptoms:

• Severe redness, sores, or hair loss  
• Persistent flaking with bleeding  
• Signs of infection (pus, swelling)  

Conclusion

Natural home remedies offer easy, calming, and practical solutions for treating itchy scalps. The benefits are bountiful and pave the way to healthier, happier hair and skin. It is essential to know when to seek medical attention for problems that persist or worsen despite gentle treatments.

Whether you are just starting your hair and scalp care journey or seeking alternative solutions, careful planning and monitoring are essential to achieving a happy, healthier you.
