Sulphate should especially be avoided by anyone who has colour-treated hair, this may strip your strands of natural oil and fade your color.

Sodium Lauryl Sulfate is usually seen in inexpensive commercial shampoos. Research has found that this chemical has the ability to degenerate protein and cell membrane on the scalp. And the last thing you would want is to break down the hair follicles’ protein building blocks.

Synthetic Fragrances

One common chemical in hair products is synthetic fragrances. This allows shampoos and conditioners to smell like roses, sunshine, and other beautiful aromas. But this chemical is also responsible for triggering asthma and cause allergic reactions to some. It also disrupts the reproductive system which can lead to cancer. Fragrances can also irritate the scalp which leads to hair loss. It is recommended that people who have a sensitive scalp should avoid scented hair products or opt for hypoallergenic shampoos.

Common paraben terms used in product labels are butylparaben, ethylparaben, and methylparaben.


Formaldehyde is known as a human carcinogen. This is usually used in hair products for preservation purposes. Because of its low cost and disinfectant qualities, formaldehyde can also be found in some baby shampoos. Hair products containing this chemical can trigger irritation on the skin, respiratory system, and cause heart palpitations. It is especially dangerous when inhaled because it causes allergic reactions and asthma to some people. Excessive exposure to formaldehyde can cause hair loss.
