Loreal Hair Care: Hair products with no sodium, potassium or cholesterol are the ones you should try, according to a new study.
The study was published Monday in the journal PLOS One.
It found that when a product is free of any of these three ingredients, it has no measurable effect on hair fallout.
The ingredients that are most likely to cause hair loss include sodium lauryl sulfate, potassium sorbate and vitamin C. The study used scalp swabs from 50 healthy volunteers and evaluated their hair levels of sodium laureate, sodium lauralate, sorbic acid and vitamin A. The researchers found that the scalp swab samples showed no evidence of scalp hair fall out, suggesting that the products may actually be reducing hair loss.
“The scalp swimmers reported that the product they used had no measurable influence on their hair loss,” Dr. Daniel J. Smith, one of the study’s authors, told The Daily Beast.
“But we can’t say that for sure.
The scientists found that scalp swabbings were “very sensitive” to the sodium laurates and sorbates, which can cause scalp irritation and cause scalp hair to fall out. “
If you do use a product, try to get a sample size that is smaller than that of your scalp, so that you can see if the scalp drops are caused by the product or not.”
The scientists found that scalp swabbings were “very sensitive” to the sodium laurates and sorbates, which can cause scalp irritation and cause scalp hair to fall out.
Smith and his colleagues concluded that “the more sodium laustrate, sorbanates, and lauryls you use, the more likely you are to have scalp hair drop out.
The more you use sodium lauringate, the less likely you will have scalp drop out, but the more you used sodium lauranceate, you are more likely to have skin irritation or scalp hair breakouts.”
The study was funded by the National Institutes of Health.
