Hairdressing chemicals allergy
Asthma and dermatitis from dyes, bleaches and persulfates.
About hairdressing chemicals allergy
Hairdressing exposes workers to a range of chemicals that can affect both the skin and the airways. Persulfate salts in bleaches and lighteners are a leading cause of occupational asthma and skin reactions, while hair dyes containing substances such as paraphenylenediamine (PPD) are well-known skin sensitisers. Frequent wet work, shampoos and other products also strip and irritate the skin. Hairdressers, barbers and salon assistants, especially early in their careers, are among the most commonly affected workers.
Sensitisation develops over repeated exposure, after which reactions can appear within minutes to hours. Skin problems typically show as dry, red, itchy, cracked or blistered hands, a form of contact dermatitis, while airway involvement from persulfate dust can cause sneezing, a runny nose, cough, chest tightness and wheeze. Symptoms often ease on days off and during holidays and flare again on returning to the salon, which is a useful pointer to a work-related cause.
Diagnosis is usually arranged through occupational health, with patch testing for skin allergy and specific-IgE or lung-function testing where asthma is suspected. Management centres on reducing exposure: wearing suitable gloves, minimising wet work, careful handling of powdered bleach to limit dust, good ventilation, prompt skin care and health surveillance. Confirmed occupational asthma or dermatitis may be reportable under RIDDOR. Because continued exposure can worsen and prolong these conditions, early recognition and protective measures matter, particularly for trainees.

Allergy safety: what everyone should know
Mild-to-moderate reaction signs
- Itching, hives or a raised rash
- Swelling of lips, face or eyes
- Tingling mouth, sneezing, runny nose
- Stomach pain, nausea or vomiting
Anaphylaxis — call 999 (UK) or 112 (EU) immediately
- Difficult or noisy breathing, wheeze, persistent cough
- Swelling of the tongue or tightness in the throat
- Dizziness, collapse, pale and floppy (young children)
- Use an adrenaline auto-injector (e.g. EpiPen) at once if prescribed, then call an ambulance even if symptoms improve
Allergy or intolerance? A true allergy involves the immune system and can escalate quickly; an intolerance (e.g. lactose intolerance) is unpleasant but not life-threatening. The symptoms overlap, so self-diagnosis is unreliable.
Getting tested: home-testing kits based on IgG are not diagnostically valid. If you suspect an allergy, ask a GP for referral to an allergy clinic for skin-prick or specific-IgE testing and a supervised food challenge where appropriate.
