“We need to start thinking of the scalp the same way we think of the skin on our faces,” says Paul Cucinello, hairstylist and CEO of Cucinello Beauty. “Touching your hair and scalp with unwashed hands is a no-no.” Though the risk of spreading COVID-19 through your hair is relatively low, Hadley King, MD, a board-certified dermatologist in New York City, says you can still spread other bacteria from your hands to your scalp, causing irritation and wreaking havoc on your ‘do. In fact, all that hair flipping may be the cause of your scalp problems. “The overproduction of bacteria and fungi on the scalp can create a disturbance in the scalp’s microbiome, causing redness, dandruff, irritation, and sometimes, more serious scalp conditions such as seborrheic dermatitis, folliculitis, eczema, and psoriasis,” says Cucinello.
Antibacterial hair care
As everyone is thinking about germs and bacteria these days, the beauty industry has stepped up with a greater focus on scalp care as skincare. You’ve probably seen scalp scrubs and brushes popping up all over, as well as products being touted as antibacterial. While it’s a new buzzword, the concept of antibacterial hair care isn’t new. A step above clarifying, it’s simply about using proven “sanitizing” ingredients to help mitigate the overproduction of certain bacteria and fungi on the scalp and strands that can cause issues like dandruff, redness, and irritation. And just to clarify (since we know you’re thinking it), antibacterial products—unless stated otherwise—kill bacteria, not viruses like COVID-19.
When should I use antibacterial hair products?
“While the idea of killing all of the bacteria that can develop on the scalp might sound tempting, it is a very slippery slope,” says Cucinello. “Balance is the key here.” As the saying goes, if it’s not broken, don’t fix it. If your scalp is healthy and you don’t notice any dryness or irritation, you probably don’t need to use antibacterial products. In fact, you can throw off the balance of the scalp’s microbiome by trying to overuse these products. Instead, Cucinello recommends following a healthy scalp care routine. You might be tempted to go days without washing or brushing your hair as work from home continues, but Cucinello says it’s important to practice a regular routine of exfoliating and cleansing the scalp to banish buildup. Scrubs and scalp brushes can help, but regularly washing and massaging your scalp in the shower usually does the trick. And remember, don’t touch your hair or scalp, especially with dirty hands. “We’ve all become lazy with our hair care routine but convenience is sometimes the enemy,” says Cucinello. Case in point: dry shampoo. It might be the first thing you reach for when your hair gets greasy, but coating your oily strands with product rather than washing them can do more harm than good. Cucinello says dry shampoo is fine every once in a while, but it can mess with your scalp’s pH if you reach for it more than your shampoo.
What ingredients should I look for and avoid?
Cucinello recommends avoiding products with coal tar, harsh detergents, and sulfates, all of which can dry out and irritate the scalp. If you are experiencing mild irritation or dry flaking, you can look for ingredients with natural antibacterial properties like tea tree oil, manuka honey, and coconut oil. Ketoconazole, zinc pyrithione, and selenium disulfide all have antifungal properties as well. And salicylic acid, which you may know from treating acne, is a beta-hydroxy acid that can be used to promote healthy cellular turnover on the scalp. If you are having more serious scalp issues like folliculitis—inflammation of the hair follicle—or psoriasis, it’s best to see a dermatologist for treatment. Now that you have the lowdown on antibacterial haircare, these are the best antibacterial products for your hair and scalp:
