Irritated Scalp

Definition: The scalp, a site of irritation, tingling, itching, tightness, and red patches, experiences temporary discomfort as long as exposure to the triggering factor persists. This phenomenon is linked to a compromised natural protective barrier, disrupted by one or more factors, leading to micro-inflammations on the scalp.
Internal and external causes: Sudden climate changes; high levels of pollution; genetic factors; hard water; repeated hair dyeing and highlighting; prolonged exposure to the sun; physical or emotional stress; hormonal changes; tobacco use; dandruff; frequent wearing of a motorcycle helmet, hat, cap, etc.; use of unsuitable shampoo/hair product; intense heat from hairstyling tools (straighteners, hair dryers, etc.); allergies or intolerances; skin conditions (eczema, psoriasis, seborrheic dermatitis); parasitic infestation (lice, etc.).
How to reduce or eliminate: Use gentle skincare products that contain active ingredients with soothing and anti-inflammatory properties (such as bisabolol, allantoin, cotton extract, etc.) on a daily basis; provide additional hydration to the scalp by applying a hair mask, for example; avoid scratching the scalp; apply cold.
Preventative steps to take: Space out hair colorings and highlights as much as possible; favor rinsing shampoos with cool water; limit the use of hats, caps, and tight or tied hairstyles; take the time to rinse out your hair treatment; reduce the frequency of using straightening irons and hair dryers as much as possible; avoid hair products containing drying and irritating substances (sulfates, fragrances, etc.); choose hair products with gentle cleansing agents (surfactants) that respect the skin's balance; limit shampooing to allow the scalp time to regenerate (1 to 3 times per week); dry your hair gently by blotting, not by shaking/rubbing; protect your scalp from sun exposure.
