Avoid scratching to prevent further skin irritation.
Pityriasis usually clears up on its own within a few weeks.
Fungal infections: when redness persists.
Fungal infections, such as ringworm (tinea capitis), cause itching accompanied by redness, scaling, and sometimes localized hair loss.
What to do?
Consult a dermatologist for an accurate diagnosis.
Follow an oral antifungal treatment and use specific shampoos.
Continue treatment even if symptoms improve to prevent recurrence.
Reactions to chemicals: beware of hair dyes.
Hair coloring can trigger allergic reactions: itching, redness, burning, or even blisters. One common culprit is paraphenylenediamine (PPD), a common ingredient in hair dyes.
How to avoid reactions?
Always do an allergy test before applying.
Opt for natural or ammonia-free dyes if you have a sensitive scalp.
Sunburn: the scalp is not spared.
The sun can burn your scalp, especially if you have fine hair or are balding. Burns cause itching, redness, and sometimes even flaking.
Protect yourself!
