Once you know what DMDM hydantoin does, you will probably look into the brands of shampoos without DMDM hydantoin in its ingredients. In times where social media has become the sole source of whether or not a particular product is suitable for our health, it is essential to do thorough research on every product before relying on it blindly. Coming to what DMDM hydantoin is, it is a preservative that is added to cosmetic products like lotions, shampoo, blushes, conditioners, and even eye shadow. It increases the product’s shelf life, and the anti-microbial properties make sure there is no fungal growth in it. It also releases a small amount of formaldehyde that may trigger skin allergies, hair loss, and skin irritation. Those who have a history of sensitive skin and eczema should avoid products with preservatives of all kinds. Here is a list of the 11 best shampoos to go for, which are free from DMDM hydantoin.

Shampoos without DMDM Hydantoin are seemingly on the rise, and we suggest you stay informed about this ingredient that one could do away with in a shampoo bottle. Since this component is not a big necessity nor adds up to the betterment of your hair’s health or provide any nourishment, shampoos could certainly be manufactured without its inclusion. Now that you know the what, the why, and the why not about DMDM hydantoin, let’s find out how you can save yourself from falling into buying a shampoo with DMDM hydantoin.

How To Choose Best DMDM Hydantoin-Free Shampoo

  • Read the ingredients list

Look for the full ingredients list of a product.  Look for the keywords “1,3-dimethylol-5,5-dimethyl”. This is the most commonly used formula in shampoos when it comes to DMDM Hydantoin. Instead choose shampoo with ingredients that are mostly sourced from natural extracts or organically sourced. Ingredients like plant oils, organic tea, root extracts, olive, fruit extracts, etc are a good place to start.

  • Not all chemicals are bad

Check for surfactants or the kind of sulfates if used in a product. Some of the commonly substituted chemicals are: sarcosines, betaines, sultaines, disodium, decyl or lauryl glucoside, etc.

DMDM Hydantoin works much like formaldehyde. It is a preservative added to all cosmetic products like eyeshadows, blushes, lotions, and shampoos and is used to increase the life of the product and prevent fungal growth. DMDM hydantoin contains chemical substances that trigger allergies and eye and lung infections in extreme cases. When used in large doses, it is carcinogenic and, at the least, may cause hair fall, dry scalp, and weakened hair follicles. So, it is always wise to choose shampoos that are free of DMDM hydantoin to ensure healthy hair growth. These shampoos are gentle on the scalp and do not cause allergies. Some formulae on our list are also vegan and cruelty-free. However, some products may take time to show desired results. So, read the reviews well to find a shampoo with all the features that you desire.
