Chemicals in your shampoo or conditioner may not be a problem, according to a new study published in the Journal of Cosmetic Science.
Researchers looked at the levels of five common hair dye chemicals, including ethylhexylglycerin, which is used in conditioners and hair-care products, and methylparaben, which has been linked to eye irritation, among other health problems.
The researchers found that methylparabinol levels were significantly higher in people who use conditioners or shampoo than in people using hair-dye products.
This could be due to the fact that people who wash their hair before using conditioners may use fewer chemicals than people who don’t.
The study is the first to investigate the link between conditioners, shampoo, and hair dye.
Previous studies have linked methylparabanol and the risk of developing eye irritation.
The new study found that ethylpentylglyceryl triisostearate, a chemical that is typically found in conditioner and hair dyes, was also significantly higher among those who used conditioners than among those using hair dye products.
The scientists speculate that people using conditioner in addition to shampoo may also use more ethylparabens than people using shampoo alone.
The authors of the study are not recommending that people stop using conditionering, but they say that people should use conditioner sparingly if they have a dry scalp.
This study doesn’t address whether the levels are harmful, and it’s possible that the increase in methylparabus levels in the study may be a result of people using more conditioners.
The same study also found that people with oily skin were significantly more likely to use conditionering and shampoo compared to those with dry skin.
These findings may help to explain why oily people are more likely than dry skin people to experience eye irritation from conditioners that contain methylparabiol.
These results are similar to studies done on the safety of shampoo.
These studies also found an increased risk of skin irritation from using conditioning and hairdye in combination, even after adjusting for skin sensitivities.
Researchers suggest that these findings may be because people who have dry skin are more susceptible to the skin irritant methylparabisol.
This type of research has been done in the lab, but this is the second study to suggest that conditioners can increase the risk for eye irritation after using shampoo.
In 2016, researchers found an increase in eye irritation following the use of conditioners containing methylparbaben.
There’s no clear link between methylparbisol and eye irritation among people who are not using conditionation.
This is a study about the health effects of hair dye and shampoo, so it is not a direct link between these two products.
