Scandal has erupted over a claim by a leading scalp health brand that scalp cleansing products may cause scalp cancer.
The product, which claims to be a “natural” scalp cleansing oil, is not a “safe” chemical, says the US Food and Drug Administration (FDA).
The FDA says it will not approve the product, “Cosmo Facial Scalp Cleansing Oil,” which was introduced in the US last month.
Cosmo is owned by Sanofi, a company that also makes the shampoo, conditioner and moisturizer Clarins.
“Cosmo believes that all products, no matter how natural, should be tested before approval for approval,” the company said in a statement on Thursday.
“Cosmos Facial Cleanser is not safe.”
Cosmos’ facial cleansing products are supposed to help relieve the condition of oily, greasy or irritated skin, according to the company’s website.
“With over 20 years of experience in the natural hair care industry, we have seen the power of natural products and the importance of maintaining our clients’ natural beauty.
We take our commitment to our clients very seriously and we will continue to provide the best product for our clients,” the statement said.
In a statement to the BBC, Cosmo said it had not tested the product.
“We are proud to be one of the first to bring the latest natural products to market with a proven track record, and we are committed to maintaining our reputation for quality and integrity,” Cosmo’s chief marketing officer, Daniel Hirsch, said.
Cosmos is one of several companies offering scalp cleansing and scalp care to the Indian market, including Shiseido, which makes products that include Botox and other facial creams.
In March, Cosmos, which is owned and operated by San Francisco-based Shiseida, filed for bankruptcy.
Its stock fell nearly 7 percent on Thursday, to $8.85.
