What are sulphates and parabens and why it is good to avoid shampoos with these ingredients?

They’re chemicals found in beauty products. Parabens are chemicals that have been used since the 1950s to prevent bacteria and act as a preservative in deodorants, lotions, lipsticks, shampoos, scrubs, and more. Sulfates are effective cleansing and foaming agents that can be found in toothpaste, shampoo, and body washes, among other products. In 1930, Procter & Gamble created the first shampoo that used a sulfate base, forever changing the world of hair care. Royal Drene Shampoo was so important to the hair care industry that a bottle of it still sits in the Smithsonian Museum

Sulfates and Parabens can cause skin irritations in some people, which, can contribute to hair loss, they have also been linked to causing dry, dull, brittle hair because it can tear apart the cuticle that covers the hair shaft, they are also known to cause frizziness and can potentially damage color-treated hair – literally acting in the reverse of the reason they are used in the first place
