[Respiratory pathology induced by inhalation of hair lacquer]
Abstract:
On the basis of a critical analysis of the literature, the authors review the various respiratory lesions imputed to the inhalation of hair lacquers. Pulmonary thesaurismosis is alleged to result from accumulation in the pulmonary parenchyma of non-biodegradable macro-molecules, such as PVP. Only isolated cases have been published and the true existence of this disease remains to be confirmed, in the absence of convincing epidemiological data as well as the lack of experimental reproducibility. Chronic inhalation of hair lacquers may, however, be responsible for bronchial irritative manifestations and obstruction of the small airways, in particular in hairdressers. Increase in the relative risk of bronchopulmonary carcinoma has not been proven.
Insights
Inhalation of hair lacquers may cause bronchial irritation and small airway obstruction, particularly in hairdressers. The existence of pulmonary thesaurismosis from hairspray components remains unproven due to limited evidence.
Area of Science:
- Occupational Health
- Pulmonary Medicine
- Toxicology
Background:
- Hair lacquers contain non-biodegradable macromolecules like PVP.
- Respiratory lesions have been anecdotally linked to hair lacquer inhalation.
- Pulmonary thesaurismosis is a hypothesized condition from inhaling such substances.
Purpose of the Study:
- To critically analyze the literature on respiratory effects of hair lacquer inhalation.
- To evaluate the evidence for pulmonary thesaurismosis and other respiratory issues.
Main Methods:
- Literature review and critical analysis.
- Examination of case reports and epidemiological data.
- Assessment of experimental reproducibility.
Main Results:
- Pulmonary thesaurismosis from PVP accumulation is not definitively proven due to lack of data.
- Chronic hair lacquer inhalation can cause bronchial irritation and small airway obstruction.
- No proven increase in bronchopulmonary carcinoma risk has been established.
Conclusions:
- The existence of hair lacquer-induced pulmonary thesaurismosis requires further confirmation.
- Occupational exposure in hairdressers poses risks of irritative bronchitis and airway obstruction.
- Current evidence does not support a link between hair lacquers and lung cancer.
