Making Change at Walmart reported in December that Walmart stores in Virginia added an extra layer of security to hair products typically used by African Americans.

“Hair products used by non-African Americans were placed normally on shelves, while products typically used by African Americans were secured in plastic boxes that cashiers had to unseal,” a representative of the pro-union group said.

Making Change at Walmart aired a television commercial in areas near the affected stores showing packages of women’s hair dye featuring Caucasian models that were easily within reach and without plastic coverings.
