Sweaty scalp? Here’s what causes it and 7 ways to get rid of it

Sweating is the body’s natural cooling mechanism that helps regulate temperature and expel toxins. This process is vital to maintain internal balance and prevent overheating. However, various factors, such as anxiety, stress, hormonal changes, or medical conditions, can trigger sweat glands excessively, leading to excessive scalp sweating. It can be very uncomfortable and may contribute to scalp odour, dandruff, and hair damage. Furthermore, constant moisture can create an environment conducive to fungal or bacterial infections. Read on to know the root cause and get rid of excessive scalp sweating.

What is excessive scalp sweating?

Excessive scalp sweating, medically known as cranial hyperhidrosis, involves sweating from the scalp beyond what’s necessary to regulate body temperature. It can affect people of all ages. While sweating is a natural bodily function required to regulate body temperature, excessive sweating, especially on the scalp, can lead to discomfort and hair care concerns. Let’s understand what causes it:

What are the causes of excessive scalp sweating?

Here are 5 common reasons you should be aware of:

1. Overactive sweat glands

Overactive sweat glands play a significant role. The scalp, like other parts of the body, contains numerous sweat glands that regulate body temperature. When these glands become hyperactive, they produce more sweat than necessary, leading to excessive sweating.

2. Genetics

“Genetics also plays a crucial role in this problem. If someone has a family history of hyperhidrosis, they are more likely to experience it themselves,” says Dermatologist and social media influencer, Dr Nivedita Dadu.

5. Physical activity

“Engaging in strenuous physical activities or exercises can lead to increased sweating, including on the scalp,” explains Dr Dadu.

6. Hot and humid climate

High temperatures and humidity levels, especially during the summer season, can trigger excessive sweating throughout the body, including the scalp.

7. Tight hats

Wearing tight hats or helmets for extended periods can trap heat and moisture, leading to increased sweating on the scalp.

8. Hair care products

Certain hair care products, especially those containing heavy oils or chemicals, can contribute to scalp sweating and discomfort.

9. Underlying medical conditions

In some cases, medical conditions such as hormonal imbalances, thyroid disorders, or neurological issues may contribute to excessive sweating.

How to manage excessive scalp sweating?

1. Wear cool clothing

“Choose loose and breathable clothes to allow your body to cool down naturally. Avoid tight caps or hats that can trap heat and suffocate the scalp, leading to increased sweating,” advises the doctor.

2. Stay hydrated

Drink plenty of water throughout the day to stay hydrated. Proper hydration helps regulate body temperature and replenishes lost fluids due to excessive sweating.

3. Manage stress

Stress can be problematic and may cause several health problems, including sweating. To manage your stress levels, practise activities such as yoga, meditation, or deep breathing exercises.

4. Choose hair care products wisely

Use lightweight and non-greasy hair care products that are suitable for your scalp type. Avoid heavy oils or products that can clog pores and contribute to sweating.

5. Avoid spicy foods

“If you are prone to excessive sweating, you should avoid consuming spicy foods,” says the expert.

Home remedies for excessive scalp sweating

1. Apple cider vinegar (ACV)

“ACV helps restore the pH balance of the scalp and can regulate sweat secretion. Mix a few tablespoons of ACV with warm water, massage it into your scalp, leave it on for 30 minutes, and then rinse it off thoroughly, explains Dr Dadu.

2. Wheatgrass juice

Incorporate wheatgrass juice into your diet, as it acts as a natural detoxifier and can help neutralise toxins in the bloodstream. This can contribute to reducing excessive sweating and body odors.

3. Lemon and coconut water

Create a scalp mask by mixing lemon juice with coconut water. Massage this mixture onto your scalp, leave it on for 15-20 minutes, and then rinse with cold water. Lemon’s alkaline properties can improve scalp quality and reduce excessive sweating.
