Shampoo Ingredient Analysis
The ingredients in Herbal Essences Repair Argan Oil Shampoo are shown above.
There are some ingredients in this formulation which are clinically shown to improve hair quality.
Argania spinosa (argan) kernel oil can protect hair against oxidative damageaccording to a clinical trial published in the Journal of Cosmetic Dermatology.
Aloe vera stimulates creation of collagen and elastin in skinaccording to a 2008 medical reviewwhich suggests it may enhance scalp health.
Ecklonia radiata extract may promote hair growthbecause a different species (Ecklonia cava) within the same genus of kelp was shown to do so in a 2013 clinical trial.
While there are some effective ingredients in this formulationthere are also some ingredients that we consider to be questionable from a health perspective.
Fragrance may be a serious risk to human health according to at least one medical reviewas we discussed in our Maui Shampoo reviews article.
Methylisothiazolinone is a synthetic preservative that induces cell death and inflammation in human cellsas documented in a clinical trial published in the Environmental Toxicology journal.
It's worth noting that the above-linked clinical trial was a test tube studywhich is a weaker standard of evidence than a trial with human participants. We still consider this data to be concerning.
Methylchloroisothiazolinone is another synthetic preservativeand the authors of a 2019 medical review on this compound concluded that "Dermatologists should be aware of this situationand counsel patients to avoid products containing [Methylchloroisothiazolinone]."
Overallwe consider Herbal Essences Repair Argan Oil Shampoo likely to strengthen and protect hairbut we don't currently recommend this product due to the three inactive ingredients listed above.

Conditioner Ingredient Analysis
The ingredients in Herbal Essences Repair Argan Oil Conditioner are shown above.
Argania spinosa (argan) kernel oilaloe vera and Ecklonia radiata extract are included in this formulationand we explained in the previous Ingredient Analysis section why we consider these ingredients likely to support hair health and appearance.
Fragrance is also included in this formulationbut the two synthetic preservatives we highlighted in the shampoo are not.
Phenoxyethanol is a synthetic preservative shown to be toxic to human cells in a 2020 clinical trial.
We consider this formulation to be healthier than the shampoo formulationbut we don't currently recommend it due to the inclusion of fragrance and phenoxyethanol.
Why Was Herbal Essences Sued?
In 2021Herbal Essences was sued in a class-action lawsuit because of a recall.
According to About Lawsuitssome Herbal Essences products were recalled because they contained benzenewhich has the potential to cause cancer.
The plaintiff alleged that the Herbal Essences products were marketed in a false and misleading waybecause benzene was not mentioned.
At the time of publishing this articleit's unclear what the status of this class-action lawsuit is.
Since the products containing benzene were recalledwe have no reason to believe this is an ongoing consumer safety issue.
