Sweat And Itchy Scalp: How To Keep Hair Fresh And Flake-Free After Exercise

1. Excess sweat after exercise can cause an itchy or flaky scalp.


2. Salt contained in your sweat can dry out the skin on your scalp and cause itchiness.


3. Excess moisture on your scalp, as well as increased heat, can create the ideal breeding conditions for fungal infections, including dandruff.


4. To limit your chances of a flaky scalp post-exercise, devise a post-workout haircare routine that uses one of Vichy’s anti-dandruff shampoos.


5. You can also limit your chances of a flaky scalp post-exercise by maintaining a healthy diet and performing scalp massages.

If you have been exercising or working out lately, you may have experienced increased irritation and itchiness on your scalp. This can be caused by excess sweat, which in certain environments can lead to an itchy, flaky scalp along with conditions such as dandruff after sweating.

Fortunately, as dermatologist Dr Maxfield explains, dandruff and sports, physical activity can benefit scalp health, provided sweat is managed properly. A good quality hair care routine is recommended to maintain a healthy lifestyle while also minimising the signs of an itchy scalp.

Whenever you exercise, your body produces sweat to cool down, including on your scalp. While sweat is mostly made up of water, about 1% contains a combination of salt and fat. If sweat remains on your scalp after a workout, the salt can clog hair follicles, causing an itchy sensation and potentially damaging hair and drying out the scalp.

It can also create a breeding ground for bacteria and fungi such as Malassezia, which is the main cause of dandruff.

As Dr Maxfield explains, excessive sweating combined with humidity creates an ideal environment for Malassezia overgrowth. Wearing a helmet or hat, frequent use of hair sprays and oils, and certain hairstyles like braids can all contribute to a humid environment that allows Malassezia to thrive. These are the common signs you can identify after a workout:

• A greasy and oily feeling around the scalp


• Frequent irritation and itchiness


• Noticeable inflammation when checking the scalp


• Flaking and scaly skin


• Acne-like bumps and pimples, especially near the follicles

Regular exercise is good for both the body and the hair, but you need to balance it with a reliable post-workout hair care regimen to avoid scalp problems. According to Dr Maxfield, working out boosts blood flow to your scalp, but sweat left on the skin feeds the fungus that causes dandruff. If you experience an itchy scalp when sweating, proper cleansing and a good hair wash routine post-exercise is key.

Maintaining a clean and flake-free scalp after a workout is a simple three-step process. If you are prone to an itchy or flaky scalp, follow this procedure:

Step 1: Wash Your Hair Gently and Thoroughly

Washing your hair with shampoo is the best way to remove excess sweat from your scalp post-workout. However, it is important that you don't just choose any shampoo off the shelf, but instead use one that is formulated for your hair and scalp. Vichy Dercos Anti-dandruff shampoos have been specifically developed for irritable and flake-prone scalps and are especially recommended by Dr Maxfield for use after a workout:

Dercos Anti-Dandruff Shampoos eliminate up to 100% visible flakes from 1st use* and provide up to 6 weeks anti-dandruff protection**

For normal to oily hair, try Vichy Dercos Anti-Dandruff Shampoo for Normal to Oily Hair. This shampoo is formulated to help purify the scalp, reduce sebum, eliminate visible flakes, and refresh post-sweat.

For dry hair, use Vichy Dercos Anti-Dandruff Shampoo for Dry Hair as it soothes and clears visible flakes without stripping moisture. For added nourishment, use Vichy Dercos Anti-Dandruff 2in1 Conditioning shampoo for up to 72H nourishment as well as eliminating visible flakes.

How regularly you should wash your hair depends on how much you sweat, the condition of your scalp, and whether you live in a humid environment. Remember to consult your dermatologist if you are unsure how often you should wash your hair. Even when you're not working out, using a specially formulated shampoo should be part of any regular hair-washing regimen.

Step 2: Dry Your Scalp Properly and Let it Breathe

After thoroughly washing your hair, make sure it's completely dry before moving on with your day. Any excess moisture or shampoo left behind could clog your hair follicles and potentially damage your hair. Instead of rubbing your hair dry, try dabbing it gently with a microfiber towel to protect your scalp. Try to avoid blow-drying your hair while wet, but if you do, make sure to use a protectant to avoid any heat damage. Finally, allow your scalp to breathe and avoid wearing any hats or hair coverings immediately after shampooing.

Step 3: Maintain Scalp Hygiene Between Workouts

Try as much as possible to keep your scalp clean and dry between workout sessions. Wash your hair 2-3 times a week, or every other day if your hair is oily. If you are already suffering from a flaky scalp, use a specially formulated anti-dandruff shampoo up to four times a week. Maintain this routine until the visible signs of dandruff are gone.

Washing your hair every day with regular shampoo can strip away the hair's natural oils. However, there are alternatives. A dry shampoo applied pre-workout can help protect the hair by absorbing excess sweat during a workout.

In addition to hair washing and maintaining a healthy scalp through regular hygiene methods, there are also ways to manage dandruff and a flaky scalp through various lifestyle choices:

• Maintain a healthy diet that incorporates foods rich in Vitamins A and E as well as healthy fats. Minimise your consumption of sugar, caffeine and alcohol as much as possible, especially in summer. Learn about the best foods for a healthy scalp and foods to avoid.


• Consider scalp massaging tools and techniques that can reduce the risk of dandruff and scalp irritation.


• Incorporate selenium disulfide into your hair care routine. Selenium disulfide has been medically proven to reduce the visible signs of dandruff, such as flaking. Discover the benefits of selenium disulfide for dandruff and how it works to soothe an itchy scalp.


• Keep up a regular fitness regime. As Dr Maxfield explains, moderate cardio activity helps increase blood flow to the scalp, supporting better oxygen and nutrient delivery. Learn more about the three sports exercises that Dr Maxfield recommends for cardio and scalp health in our video.

Maintaining a good exercise and workout regimen in addition to a quality hair care routine is key to maintaining a healthy scalp. It is important to maintain good hair hygiene after activities such as sports, and by adopting Vichy’s approach for a healthy scalp.
