What type of microorganisms does this shampoo target?
It acts primarily on fungi linked to dandruff, such as Malassezia species, through selenium sulfide; it is not formulated or indicated as an antiviral or as a general bactericidal disinfectant of the scalp.

How long does the anti-dandruff protection last?
Recurrence protection has been described for up to 6 weeks after the initial protocol. In approximate time terms, this equates to about 1,000–1,100 hours of monitoring after completion of the shock treatment.

Is it suitable for sensitive or atopic skin?
The available information indicates tolerance in sensitive and atopic skin; however, individual response may vary and in cases of very reactive skin, assessment by a healthcare professional is recommended.

How often should it be used during a crisis?
In acute crises, the usual regimen described is to apply it three times a week for four weeks. After the situation stabilizes, maintenance use is recommended once a week.

Can it be used with hair coloring or treatments?
Specific data on interactions with all cosmetic or chemical treatments are not available; the selenium sulfide formulation may alter the appearance of certain dyes if not rinsed thoroughly. For technical procedures, assess compatibility with professional services.

Does it include recharging and how does it affect the environment?
The pack includes a 390ml refill, which allows for a reduction in the frequency of primary packaging purchases and decreases the use of plastic per volume of product.

Is it safe during pregnancy and breastfeeding?
There is no comprehensive public clinical data for all situations; as a precaution, it is advisable that administration during pregnancy or breastfeeding be assessed by the responsible healthcare professional.
