No. Today parabens, being good preservatives against bacteria, fungi and yeasts, have a bad press because there have been some cases of contact allergy in healthy skin, as stated by the AEDV (Spanish Academy of Dermatology and Venerology).
Today parabens are not only present in cosmetics, but also in food, medicines..., so there are many moments to which we are exposed and sometimes they can alter the balance of the skin, sensitizing it.
This has led companies like ours to innovate, which is always necessary when you want to make progress in health, and to value other preservatives in their formulas. Most of the companies following the trend in natural cosmetics today opt for the use of preservatives allowed by ECOCERT natural cosmetics regulations, chemical or synthetic preservatives that have not presented toxicity studies.
What about these other preservatives? They are more unstable, can react with components of the formula, and their efficacy is highly dependent on pH, indicating the need for good formulation practices. So always trust quality brands for your hair care.
