Short answer: Start an itchy-scalp reset by stopping new fragrance, essential-oil, dye and exfoliating products; wash with lukewarm water and a mild shampoo; avoid scratching and tight styles. This can reduce routine irritation, but itch has many causes—including contact dermatitis, dandruff, psoriasis, lice and infection. Symptoms that persist, spread or accompany sores or hair loss need professional assessment.
Common triggers and conditions
New shampoo, fragrance, essential oils, hair dye, adhesives, preservatives or styling sprays can irritate or cause allergic contact dermatitis. Hot water, sweat, tight headwear and dry shampoo residue add mechanical or chemical stress. A reaction may extend to ears, eyelids or neck where product runs. (PubMed-indexed research (PMID 35318978))
Seborrhoeic dermatitis is another common itchy, flaky cause. Psoriasis can form thicker plaques; lice cause contagious itch; fungal infection can break hairs. A low-irritation routine is a reasonable first step but cannot distinguish these conditions reliably.
A seven-day low-irritation plan
Pause scalp scrubs, essential oils, dry shampoo and new styling products. Wash when oily with a small amount of mild shampoo, massage using fingertip pads and rinse thoroughly. Use conditioner on lengths, keeping it off the scalp unless directions allow. (DermNet clinical resource)
Keep nails short and use a cool compress instead of scratching. Wash hats and pillowcases and clean brushes. If one suspected product preceded the flare, do not “test” it repeatedly on irritated skin; save the label for a clinician if the reaction persists.
Product-selection filters
- Simple cleansing objective with clear directions.
- No known personal allergen in the current INCI.
- Low fragrance exposure when scent is a suspected trigger.
- No abrasive particles during an active itchy flare.
When gentle care is not enough
Seek care for intense nighttime itch, visible lice or nits, pus, crusts, swollen lymph nodes, spreading redness, hair loss or scarring. Recurrent dermatitis may need diagnostic patch testing, while dandruff may need a targeted active rather than a generic sensitive shampoo. (American Academy of Dermatology guidance)
The current Silouel shampoo page describes the product as delicately fragranced. That may be acceptable for many users but is relevant if fragrance is a suspected trigger. It is a cosmetic cleanser and is not documented as treating seborrhoeic dermatitis or allergy.

Frequently asked questions
Does a sensitive-scalp shampoo have to be fragrance-free?
Not necessarily, but fragrance is a common trigger. People with suspected fragrance allergy should prefer clearly verified fragrance-free formulas.
Should I stop washing an itchy scalp?
No. Residue and oil can worsen some causes. Wash gently at a frequency that keeps the scalp clean without hot water or scrubbing.
Can peppermint oil calm itch?
Cooling may distract from itch but can also irritate. It does not diagnose or treat the underlying cause.
When is patch testing useful?
Clinician-administered patch testing can identify contact allergens when dermatitis recurs. Home spot tests cannot replace it.
