The scalp is the skin covering your head that supports and promotes hair growth. This area is rich in blood vessels. Your hair goes through several growth phases, and naturally, old strands shed to make room for new ones. However, your scalp's health can be compromised by various conditions, including illness or simply dryness. This can lead to uncomfortable symptoms like itching, tingling, and burning sensations.
Understanding Itchy Scalp and Dandruff
A dry scalp leads to itching, burning sensations, irritation and pain, redness, and hypersensitivity.
The first thought one has about an itchy scalp, or one that 'scratches' as it's commonly said, is that we have dandruff; a true reasoning, but not always, because scalp dryness can stem from several sources and create a disruption in sebum production. These disruptions come from:
- A shampoo that strongly irritates you: methylisothiazolinone is a preservative in highly sensitizing shampoos;
- A parasite that has taken root;
- A skin condition: eczema, seborrheic dermatitis, or even psoriasis, which lead to skin lesions;
- Hair dyes;
- Prolonged exposure to sun or salt water;
- Tobacco consumption;
- Excessive relaxers and straightening;
- Stress or fatigue.
Dandruff is the sworn enemy of the scalp, as it is very bothersome and annihilates any form of aesthetics. One in three people suffers from dandruff, each in a different way. It can be numerous and persistent. Skin flakes: the medical definition of dandruff; a consequence of an accelerated renewal of scalp cells. They are white and generally fall off on their own. More common on normal, dry, and coily scalps, they can quickly detach and spread onto clothing. It's not just the hair that falls victim, as eyebrows can sometimes harbor them.

As highlighted above, the consequences of an irritated and dry scalp are diverse and varied. Itching becomes frequent with the appearance of redness. Dandruff detaches from the dermis more quickly, and the layer protecting the scalp becomes more fragile and sensitive to any other external factor, leading to micro-inflammations. It's not difficult to realize you have dandruff. If nothing is done, this dandruff can become oily with much more itching.
A dry scalp or neglected or untreated dandruff can lead, especially if it's seborrheic dermatitis, to more pronounced itching, a complete covering of the scalp with crusts, down to the base of the hair; it can even spread to the neck, ears, and in extreme cases, hair loss; premature hair loss, moreover.
