title: Part 2 of a 4-part series Hair Products: Trends and Alternatives: Data from the American Contact Alternatives Group.
abstract: OBJECTIVE
  To provide updated data on usage of ingredients that are common potential contact allergens in several categories of hair products. To identify useful alternative products with few or no common contact allergens.
  
  
  METHODS
  In November 2009, the full ingredient lists of 5,416 skin, hair, and cosmetic products marketed by the CVS pharmacy chain was copied from CVS.com into Microsoft Word format for analysis. Computer searches were made in Microsoft Word using search/replace and sorting functions to accurately identify the presence of specific allergens in each website product.
  
  
  METHODS
  Percentages of American Contact Dermatitis Society core series allergens (and other common preservatives and sunblocks) were calculated.
  
  
  RESULTS
  The usage of American Contact Dermatitis Society core series allergens (and other preservatives and sunblocks) in hair products is reported.
  
  
  CONCLUSIONS
  Data on allergens and alternatives for hair products is not widely published. This article reviews some of the common potential allergens in hair products, including shampoos, conditioners, and styling products. Suitable available alternative products for patients with contact allergy are listed.
