Harmful ingredients

Propylene Glycol

Propylene Glycol is commonly added to hair conditioners and moisturising lotions to give a smooth and nourishing feeling to your hair.


For industrial use, it is used as an antifreeze and pressure control liquid in drinking water systems. If used for a long time, it can be harmful to the skin. It replaces and drives away natural compounds that are beneficial to skin health while providing moisture.

If you are exposed to it for a long time, it will damage the liver and kidneys. Even low concentrations can irritate the skin and cause dermatitis.

Sodium Lauryl / Laurent Sulfate (SLS)

Sodium Lauryl/ Laurent Sulfate (SLS) is commonly used in shampoo, facial cleansers, and shower gel to remove dirt and create foam. It is also used in industrial products to clean floors, as an engine degreaser, and in car wash soaps.

SLS is a corrosive substance, it can penetrate into the eyes, brain, heart, liver and other tissues and organs and stay for a long time. If it enters hair follicles, it may cause hair loss. Infections of the eyes can cause cataracts. Bath products containing this ingredient can cause rashes as the skin’s protective layer is eroded.

Using a corrosive method to achieve the cleaning effects will break down the lipids on the epidermis and damage the skin’s natural function of controlling and regulating humidity.

Diazolidinyl Urea

Diazolidinyl Urea is used as a preservative in some hair products. It contains “amide” which can make hair dry. It also releases “formaldehyde”, experiments have proved that it can cause lung cancer and damage DNA.

Urea is added to dilute hair conditioner.

Polyquaternium is often added to hair products to create a protective film that prevents hair conditioner from solidifying. However, polyquaternium contains “quaternary ammonium compounds”, which can cause hair to become dry and irritate the scalp.


Urea is added to dilute hair conditioner.

However, urea contains “amide” which can make the hair dry. Additionally, its hair care effect can only be worked on the surface of the hair.


Hair conditioner containing “dimethicone” makes hair silky and smooth.

However, it can block water and nutrients from reaching the hair’s protective outer cuticle. This can eventually make the hair dry and brittle, and it may even weigh the hair down and make it appear flat.
