Do repair shampoos really work? The answer in a Swiss analysis.
Don't store avocado like this: it's dangerousA Swiss study warns about so-called "repairing" shampoos that little or nothing protect the hair, but are full of silicones and plastics
They are called "repairers" because they have the miraculous purpose of remedying damaged hair. As we know, dyes, wild folds and various backcombing do not help the hair and this is how there is a tide of variations of washes on the market that promise the impossible: to restore vitality to destroyed hair. But is not so. Do repair shampoos really work?
According to a survey conducted by a Swiss magazine, in fact, many products that are on the market are not actually able to guarantee to "protect" the hair and, in addition, almost all contain unwanted substances.
This is the mensile K-tip, which he tested 12 very common shampoo brands carrying out a specific analysis: how much hair, despite shampooing, breaks while combing?
Analyzes
For the analyzes, 12 shampoos were subjected to four separate laboratory tests at the SGS Institut Fresenius in Taunusstein, in which several points were taken into consideration:
Fragrances: 26 fragrances with increased allergic potential must be declared at 100 mg / kg on shampoo bottles. In the evaluations, K-tipp subtracted 0,1 point from 100 mg / kg for weakly allergenic fragrances, one point for strongly allergenic fragrances
Effectiveness: to evaluate the effectiveness, the experts applied each shampoo to five heads, leaving it on for two minutes. Then they rinsed and combed with a machine that simulated 20 brushings
Polycyclic aromatic compounds: considered hazardous substances for health, the shampoos that contained them had a 0,5 point penalty
Dioxane: suspected of causing cancer, no traces of dioxane were found in any product in the analyzes.
The results
The repair shampoos tested differed enormously from each other in their protective effect.
Depending on the product, they range from 0,4% of broken hair ("Salonplex Repaired Revolution" di Syoss) al 9,1% ("Cien Pro Vitamin Shampoo Repair & Care" by Lidl). In the comparison, moreover, 4,3% of the hair broke with strands of hair washed only with water and the products in which the hair fell out more than washing with water received an insufficient evaluation and are: repair shampoos guhl, Herbal Essences, Kérastase e Lidl.
Overall, only 7 products passed the test: their use would not have caused breakage during brushing. Among these appear some brands such as Fructis, L'Oreal and Nivea, while two Pantene and Kerastase have been rejected.
The presence of silicones
As expected, 9 of the 12 products analyzed contain plastic silicones, which cover the hair like a protective shield and make it easier to comb, but in the long run they weaken the hair even more.
The brands of shampoo that do not contain silicones are:
- Rausch
- Kérastase
- Pantene Pro-V
But they still contain critical fragrances.
In light of this, the fact remains that we must only rely on products with an impeccable INCI and, why not, rely on good old natural remedies also for the care of our hair.
