"For poor quality sunscreen, not only is it ineffective, but it can also cause sunburn, dermatitis, long-term use can cause heavy metal contamination, affect hormones, for pregnant women it can affect the fetus...", said Doctor Hung.

Sharing the same opinion, a dermatologist at Xuyen A General Hospital (HCMC) said that using poor quality shampoo will cause chronic inflammation of the scalp, leading to weak hair, breakage, and more damage. If the shampoo contains many harmful ingredients, a large amount of detergent can penetrate the skin, causing irritation and increasing the risk of cancer.

In particular, with the ingredients formaldehyde and parabens, although many products are advertised as free of formaldehyde and parabens, they can still appear in many shampoos on the market.

Formaldehyde is a chemical compound used as a preservative in some consumer products, including shampoos, to help prevent the growth of bacteria, mold, and yeast, extending shelf life.

Formaldehyde can cause irritation, allergic dermatitis and respiratory diseases. Many studies show that people who are regularly exposed to this substance are at risk of leukemia and cancers such as sinus and nasopharyngeal cancer.

Parabens are chemical preservatives that have long been used in beauty products such as shampoos, lotions, etc. Studies have shown that parabens can be quickly absorbed through the skin and penetrate into the body's tissues. This causes allergic contact dermatitis and other problems such as redness, irritation, itching, peeling skin, and dry and damaged hair.
