Seborrheic dermatitis is a fairly common skin condition that causes red, itchy, and flaky patches, most often affecting the scalp, face, and other oil-prone areas of the body. While it’s not dangerous, it can be frustrating to deal with, especially since flare-ups tend to come and go. Lately, hypochlorous acid (HOCl) has been gaining attention as a natural way to treat seborrheic dermatitis by reducing inflammation, fighting off yeast overgrowth, and soothing irritated skin.

What Causes Seborrheic Dermatitis?
Seborrheic dermatitis happens when your skin’s oil production triggers an overgrowth of yeast (specifically Malassezia). This leads to the irritation, flaking, and inflammation that are hallmarks of the condition. While it’s often seen on the scalp (what we call dandruff!!!), it can also appear in other areas like your eyebrows, nose, and chest.
To manage seborrheic dermatitis, you need a treatment that addresses both the yeast overgrowth + the inflammation that comes with it. That’s where hypochlorous acid comes in, with its powerful antimicrobial and anti-inflammatory properties.
How Hypochlorous Acid Helps Treat Seborrheic Dermatitis
Fights Yeast Overgrowth: The yeast Malassezia is a natural part of your skin’s microbiome, but when it grows out of control, it leads to problems like seborrheic dermatitis. Hypochlorous acid is antimicrobial, helping to reduce yeast levels and restore balance to your skin.
Reduces Inflammation: Seborrheic dermatitis is notorious for causing redness, itching, and flaky skin. Hypochlorous acid’s anti-inflammatory benefits calm the skin, reducing both the visible signs of dermatitis and the discomfort that comes with it.
Soothes Itching and Irritation: One of the most annoying symptoms of seborrheic dermatitis is that persistent itching. Hypochlorous acid helps relieve that itch, making you less likely to scratch, which can cause further damage and even lead to infections.
Safe for Sensitive Skin: One of the best things about hypochlorous acid is that it’s gentle enough for all skin types. It’s non-toxic and can be used daily, making it an ideal choice for those with seborrheic dermatitis who want to avoid harsh chemicals or steroids.
How to Use Hypochlorous Acid for Seborrheic Dermatitis
Using hypochlorous acid is simple. After cleansing, spray it directly onto the affected areas of your skin. If you’re using it on your scalp, part your hair and spray it right onto the skin. Let it air dry, then follow up with a gentle moisturizer or leave-in conditioner if needed. If you are using hair extensions and/or clip-in hair extensions you may also want to cleanse the tip of the extensions with a hypochlorous acid spray due to its antibacterial properties.

Long-Term Management of Seborrheic Dermatitis with Hypochlorous Acid
Although seborrheic dermatitis has a tendency to flare up and then subside, making hypochlorous acid part of your regular skincare routine can help minimize flare-ups and keep your skin balanced. Its antimicrobial properties control yeast levels, and its soothing action helps reduce the itching and irritation that make the condition so frustrating to live with.
