Can Dye From Clothes Cause a Rash?
What is contact dermatitis?
Those prone to contact dermatitis should consider wearing unbleached, nondyed garments that are labeled as such. They could also wear clothes labeled as dyed with nontoxic dyes.
According to the Health and Safety Assessment of the Washington State Department, clothing dermatitis can result from dyes in clothes rubbing off easily on the skin. The department explains that commercial dyes are easily transferred to people in this way.
Remedies
According to the Safety and Health Assessment of the Washington State Department, blues and violet synthetic dyes often create skin irritation for those with this sensitivity.
Instead, select garments that are not dyed with artificial dyes or those that are not dyed at all.
Preventive measures
It will be a process of trial and error to discover which types of clothing will not irritate an individual with clothing dermatitis.
