DMDMH IN HAIR CARE: SHUB LAW

Many hair care products claim to “smooth hair.” But a chemical included, DMDMh, may be contributing to your hair loss and scalp issues. Shub Law’s attorneys have been involved in consumer product litigation for decades, and have lead the charge in DMDMh litigation for almost a year. If you think you’ve used a product with DMDMh in it, read on – it’s time to fight back!

Could your "hair smoothing" product actually contribute to hair loss? Shub Law is investigating products with a DMDMh culprit of hair loss - and we want to help you!

WHAT IS DMDMH?

DMDMh (dimethlodimethyl hydantoin) is a preservative used in cosmetic products, and it is typically used to lengthen the life of personal care products. But, DMDMh is a also “formaldehyde donor”. So this means that, over time, it will slowly release formaldehyde – a known human carcinogen1 – into the skin2.

Scientists have studied DMDMh and human reactivity since the 1970s, and one study in 1987 confirmed a link between certain amounts of DMDMh and skin conditions, such as dermatitis.3 The FDA even recognizes DMDMh as a top allergen in consumer products.4 Yet, despite overwhelming evidence of its danger, many manufacturers continue to use this preservative in their product.

WHAT PRODUCTS CONTAIN DMDMH?

The attorneys at Shub Law are actively litigating cases against Unilever for their “TRESemme” Keratin Smooth products and their “Suave Professionals” products; Straight Arrow Products for their Mane ‘N Tail products; and against Johnson & Johnson for their OGX line of products. However, Shub Law continues to investigate many more products, including Selsun Blue and Aussie hair care products, and still other hair smoothing products that may contain DMDMh and place consumers at risk.
