Keep the free-from wording narrow
Faith’s current maker page says the selected shampoo is free from SLS and SLES,while its ingredient list includes Ammonium Lauryl Sulfate. Those names should not be collapsed into a single identical ingredient. The source claim is not rewritten as contains no sulfate surfactants,because that would go beyond the actual wording and list.
Compare the selected Simple list
The selected Simple list contains Sodium Laureth Sulfate. That is a concrete ingredient difference between the two cosmetic references. It does not by itself establish that one is universally gentler,safer or better for a particular scalp. This site has not tested either formula’s cleansing,irritation or hair effects.
A shopping-brief example
If a buyer’s requirement is specifically to avoid a named ingredient,record the exact name and compare the current selected labels. If the requirement is a broader category avoidance,do not assume a marketing abbreviation answers it. Obtain an appropriate maker clarification rather than treating an incomplete keyword match as personal approval.
Do not infer from the medicine
The Nizoral leaflet lists sodium lauryl ether sulphate among its other ingredients and has a specific excipient warning. That source belongs to the medicine record,not a universal verdict on every cosmetic containing a similarly named ingredient. The numerical excipient line in the extracted leaflet is unresolved here;no concentration is calculated or repaired.
Keep the conclusion useful
The next purchase decision can be a focused question about the actual formula rather than a blanket good-or-bad ingredient score. Check the current original pack and relevant professional guidance where personal suitability is involved. No scalp diagnosis,ingredient-danger ranking or universal sensitive-skin guarantee is generated by the tools.
A concrete decision record
Compare the actual strings:Simple lists Sodium Laureth Sulfate;Faith lists Ammonium Lauryl Sulfate. A shopper seeking the exact maker SLS/SLES-free claim can see why the Faith wording does not answer a broader no-sulfates request. The useful next question is the ingredient requirement itself,rather than a simplified clean-formula score.
