A sensitive scalp caused by a broken protective barrier
Just like the skin, the scalp is covered by a protective layer. Think of the layer as a brick wall and imagine that the bricks symbolize the horn cells. The cement between the bricks consists of lipids, i.e. oily substances. External influences can lead to the removal of part of the lipids, or in our example, the cement. The barrier (our brick wall) will then become leaky. Too much moisture escapes and the ways are cleared so that harmful substances can enter. This irritates the scalp and it reacts with itching, burning, redness, or tightness.
Scalp issues due to hair care mistakes
Do you wash your hair every day and then proceed to use styling products containing alcohol, such as styling gel or mousse? Over time, this will dry out the scalp. If you must wash your hair daily, make sure to use a very mild shampoo. Leave out the styling products containing alcohol for a while and instead style your hair using a leave-in conditioner, styling spray, or wax.
Climate change can aggravate the problem
Dry heated air in winter and air conditioners in summer can certainly lead to a sensitive scalp and can irritate the skin overall. If you find yourself in environments with air conditioning or heaters and notice your scalp worsening, then moisturizing shampoo, conditioners, and leave-in hair treatments are a true blessing for hair and the scalp. In the process, you will replenish the scalp’s moisture reserves without adding lipids in large amounts. Lipids (fat) can weigh hair down, especially fine hair.
Avoiding extreme heat to protect the scalp
It’s said that showering under very hot water can lead to problems with the scalp, which is why experts always recommend at least washing your hair with cold or lukewarm water. Sun damage (caused by not wearing a hat during summer, for example) and over-using hair dryers, curling irons, and straighteners – especially without using heat protectant spray – are also common causes for scalp irritation.
Your dermatologist may come to the rescue
Persistent itching may be the symptom of a fungal disease affecting the scalp. Redness and large dandruff flakes make a fungal disease even more likely. An oily scalp is particularly prone to fungal overgrowth because the fungus likes the environment. If your scalp is oily and itchy, then you should consult with a dermatologist as to why you are suffering from a sensitive scalp.
