These products and lifestyle changes may help improve the situation
Have you ever had an annoying itch on your scalp that just won't quit? It pops up during the most inopportune moments, is completely unwelcome, and sticks around way longer than it should. That constant itch can turn even the easiest tasks into a bit of a struggle — and it can throw you off your game and steal all of your focus.
In all honesty, it's not just about the itch — it’s finding the source that brings the annoyance to new-found heights. Is it that new TikTok trendy shampoo you recently bought? Is stress getting under your skin (literally)? Or is this dry scalp, dermatitis, or something more serious?
Figuring out why your scalp is itching is key to getting some relief. Below, we help you identify the common culprits behind that irksome scalp itch. We also explain why scalp lotions may be the solution you have been looking for. Let's dive in and tackle this head-on—no pun intended.
Q: I've tried everything, but my scalp is still so itchy. What's causing my scalp to itch?
A: An itchy scalp can occur for several reasons, says Deanne Mraz Robinson MD, FAAD, a fellowship-trained, board-certified dermatologist and president and co-founder of Modern Dermatology. Two of the most common causes are Dandruff and seborrheic dermatitis. While these conditions might seem similar, they have distinct characteristics. "Dandruff is the result of dry skin on the scalp, which can feel itchy and cause flaking. Seborrheic dermatitis can present similarly; however, it also includes visible inflammation, pruritus (itchy skin), and erythema (a type of skin rash).”
For those grappling with more than just dandruff, Dr. Robinson points to a more complex condition — psoriasis, which occurs when our body's defence mechanisms can go into overdrive, leading to discomfort. “Scalp psoriasis presents when a person’s immune system has signalled the skin to produce skin cells too quickly, resulting in plaques of skin cells that can be itchy and painful."
Specific products can also cause an itchy scalp — even if you're not using them on the regular, Dr. Robinson says. “Scalp eczema (contact dermatitis) is linked to specific topical irritants that touch the scalp’s skin." Common irritants include fragrance, alcohol, and chemicals in hair dye. So, while you may be obsessed with that new amazingly floral-scented hair product or your recent dye job, your scalp may not be as enthused.
How Scalp Lotion May Help
According to Dr. Robinson, if you are going to use a scalp lotion to help alleviate some itch, pay close attention to the ingredients. Humectants such as squalane are important for hydration, aloe and botanicals for soothing, and ceramides and peptides to support scalp skin and overall hair health.
Meanwhile, avoid fragrances as they’re one of the biggest sources of scalp irritation. For those who are sensitive to fragrance or experience scalp sensitivity in general, Dr. Robinson recommends opting for a lightweight serum with scalp-friendly ingredients such as her personal favourite, SEEN’s Restore Scalp Serum.
Also, depending on the source of your itch, how often you use a scalp lotion may change, Dr. Robinson says. For example, if you tend to experience an itchy scalp in the winter when the temperature drops, you may need to use a scalp lotion more often than you would in the summertime when your skin naturally produces more sebum (oil) and can nourish itself.
How Lifestyle and Environment Impact Your Scalp
To no surprise, your lifestyle choices and the environment play a role in your scalp health, especially as it pertains to itchiness, says Dr. Robinson “If you are struggling with seborrheic dermatitis, you might try eliminating yeast and mould from your diet as they may contribute to the already too prominent presence of Malassezia (a type of fungi) on the scalp. This would include eliminating bread, cheese, wine, beer, and other foods made by yeast or fungi.”
Additionally, she notes that managing stress and adjusting your shower temperature (from any extreme) can help reduce scalp inflammation. You also should address issues like dandruff, psoriasis, and eczema.
A healthcare provider can help you understand the unique causes of these conditions and find the right treatment regimen. Also, choosing scalp lotions wisely and adjusting your diet and lifestyle are key steps towards relief. With these tips, you can effectively soothe your scalp and enjoy greater comfort and scalp health.
