The City Council's Trading Standards Service is continuing to warn the public about dangerous 'black henna' (mehndi) products. Henna products are popular all year round. They can be found at summer shows and events in the form of henna tattoos, and are increasingly used around the Eid period by young children and adults to decorate hands, arms, and dye hair.
Henna is naturally a shade of orange/red, and in its natural form is perfectly safe to use, and a good alternative to chemical based hair dyes.
Henna has however been found on sale in premises in other parts of the country and these products have been found to contain additional chemicals. These chemicals are added to the henna to make it a darker shade/black. The additional chemicals are usually Phenol and PPD.
The Cosmetic Products Enforcement Regulations 2013 SI 2013 No. 1478 (external site) do not permit the use of phenol in any cosmetic product. Phenol has been found to have a corrosive effect to the skin, and the side effects can remain for months after it has been used.
PPD is only permitted to be used in permanent hair dyes, and is not safe when used in non-permanent hair dyes such as henna, due to the lack of a suitable coupling agent. When used in non permanent hair dyes PPD has a sensitising effect. This means that users may be fine after the first few applications, but in some cases will gradually become more sensitive over time leading to allergies. PPD in this form has also been linked to mutagenic effects and anaphylaxis. Anaphylaxis is a severe allergic reaction that is rapid in onset and in some cases can be fatal. It typically results in a number of symptoms including an itchy rash, throat swelling, and low blood pressure.
The safety message is clear. Use natural henna in its orange/red form and avoid darker shades of henna. It is also a good idea to carry out a patch test, to check for any reaction before applying any product to the hair or skin.
The City Council's Trading Standards Service has now undertaken a widespread inspection and sampling programme of retailers and wholesalers across Newcastle, which sell henna hair and skin products. Following the analysis of some 13 samples of products as purchased by officers, the Trading Standards Service has now advised all the retailers, where non compliant products were found in their premises to remove those products from sale.
