When you have dandruff, finding the right scalp care routine can be a challenge. But does swimming outdoors make this better or worse? For some, a trip to the beach or a swim in a lake is a chance to relax, unwind, and enjoy the outdoors. It can be especially challenging if you have just got your scalp and hair balanced with the right products, only to have it thrown out by your sports or outdoor hobbies.
Saltwater and Freshwater can behave very differently on your scalp, so we look at both below.
How Saltwater Affects Your Hair and Scalp
Saltwater, like that found at the beach, has a number of effects on the scalp and hair. While it may seem refreshing, especially on a hot day, there are both pros and cons to consider when it comes to dandruff.
The Benefits of Saltwater for Dandruff:
Natural Exfoliation: Saltwater acts as a natural exfoliant. It can help to gently scrub away dead skin cells from your scalp, which could be helpful for reducing flaky skin associated with dandruff. The abrasive quality of salt can help clear away the scales that form when excess oil and dead skin cells build up, potentially reducing the appearance of flakes.
Antimicrobial Properties: Salt has antimicrobial and antifungal properties, which can be beneficial for people who experience dandruff caused by Malassezia, a yeast-like fungus that thrives on the scalp. By helping to control excess oil and reduce fungal growth, saltwater may contribute to a cleaner, healthier scalp environment.
Improved Circulation: When swimming in the ocean, the action of saltwater against your scalp can increase blood flow to the area, which may promote healthier hair follicles and improved scalp health overall. Increased circulation helps nutrients reach the scalp, aiding hair growth and reducing scalp irritation.
The Drawbacks of Saltwater for Dandruff:
Dryness: One of the biggest downsides of saltwater is that it can be very drying to both the scalp and hair. While saltwater may temporarily remove flakes, it can also strip the scalp of its natural oils. This can lead to dryness, which might worsen dandruff in the long run. If your scalp becomes too dry, it may produce even more oil to compensate, contributing to further flakiness and irritation.
Potential Irritation: For some, the salt content in the ocean water can be irritating, especially if you already have a sensitive or inflamed scalp. Salt can cause stinging and exacerbate irritation if your scalp is already compromised from dandruff or scratching.
How Outdoor Freshwater Affects Your Hair and Scalp
Outdoor freshwater from lakes, rivers, and ponds has a very different effect on your scalp and hair compared to saltwater. While it lacks the salt that might strip your hair and skin of moisture, freshwater still has its own unique characteristics.
The Benefits of Freshwater for Dandruff:
Hydration: Freshwater, especially from clean, natural sources, tends to be much more hydrating than saltwater. If you’re swimming in a freshwater lake or river, it can help nourish your hair and scalp without the drying effects of salt. Hydration is key for a healthy scalp, and it can help prevent the flakiness and irritation that often come with dandruff.
Reduced Irritation: Freshwater generally has a much gentler impact on the skin compared to saltwater. This is particularly beneficial for anyone with a sensitive scalp or seborrheic dermatitis (a common cause of dandruff). The soothing properties of freshwater can help to calm irritation, and the absence of harsh chemicals or salts means that there’s less chance of exacerbating scalp issues.
Purification and Clarifying: In some areas, freshwater may have natural minerals that can help purify and clarify the scalp. Certain minerals in freshwater, such as magnesium or calcium, may contribute to overall scalp health by improving its ability to resist infections or fungi that cause dandruff.
The Drawbacks of Freshwater for Dandruff:
Contaminants: While freshwater from a natural source can be soothing, it can also contain bacteria, algae, and pollutants. Exposure to contaminated water can lead to scalp infections or irritations, which could potentially worsen dandruff if the scalp’s natural barrier is compromised.
Lack of Cleansing Action: Unlike saltwater, freshwater doesn’t offer the same exfoliating or antimicrobial properties. While it can be more hydrating, it won’t actively reduce the fungal or bacterial factors that might contribute to dandruff.
How to Maximize the Benefits of Saltwater and Freshwater for Dandruff
If you want to make the most of these natural water sources without worsening your dandruff, here are a few tips:
Rinse Your Scalp After Swimming: After a swim in saltwater or freshwater, always rinse your hair and scalp thoroughly with clean, fresh water to remove any buildup of salt or contaminants. This will help prevent dryness and irritation.
Follow Up with Moisturizing Products: To balance out any drying effects, follow your swim with a hydrating conditioner or scalp treatment. Look for products with ingredients like aloe vera, jojoba oil, or glycerin to replenish moisture to your scalp.
Use Anti-Dandruff Treatments: If you swim regularly in saltwater, consider using an anti-dandruff shampoo with proven active ingredients.
Avoid Overexposure: Limit the time you spend in saltwater, especially if you have a sensitive scalp. Overexposure can exacerbate dryness and irritation, leading to more dandruff.
