What is the scalp?
The scalp is the skin covering the skull. Rich in hair follicles, sebaceous glands and blood vessels, it plays a part in maintaining the hair’s balance right from the root. The follicles are the structures from which hair grows, whilst the sebaceous glands produce sebum, which helps to protect and lubricate the scalp as well as the hair fibre.
As it is highly exposed, the scalp can sometimes be sensitive. Dryness, overly harsh products, stress, skin imbalances or reactions to certain treatments can disrupt its balance and cause itching. Depending on the case, the discomfort may be occasional or recur regularly, with symptoms that are more or less visible. Here are the main causes:
A dry scalp
When the scalp lacks moisture or lipids, it can become dry, tight and itchy. Cold weather, wind, washing your hair too often, very hot water or using shampoos that are too harsh can weaken the hydrolipidic film and exacerbate this feeling of discomfort.
A reaction to certain hair care products
Shampoos, conditioners, hair colourants, styling products… Some products may contain ingredients that sensitive scalps do not tolerate well. If a reaction occurs, itching, redness or a burning sensation may develop, particularly after using a new product or one that is too harsh.
An imbalance in the scalp
An unbalanced scalp can be associated with excess sebum , dandruff, flaking or patches. Certain conditions, such as seborrhoeic dermatitis or folliculitis, can cause persistent itching and require medical advice if the symptoms persist or worsen.
Certain skin conditions
Psoriasis, eczema or even lichen planus can also affect the scalp. These conditions are often accompanied by redness, flaking, patches or more severe irritation. If you experience severe, recurrent itching or itching associated with visible lesions, it is advisable to consult a healthcare professional.
Stress and fatigue
Stress, tiredness or periods of tension can affect the skin’s balance, including that of the scalp. They can lead to feelings of discomfort, tightness or itching, particularly in people who are already prone to irritation or skin imbalances.
