Do products really have the ingredients they claim to have. E.g. ';henna/almond/lemon'; shampoo ??

I have always wondered about this and would love to know whether we can really believe labels. Is there any public institution responsible for checking the labelling of products and whether the labels are fact or fiction?Do products really have the ingredients they claim to have. E.g. ';henna/almond/lemon'; shampoo ??
I believe they have the abstract like the residue of the ingredients they suppose to have like some sodas that say strawberry don't have strawberries.Do products really have the ingredients they claim to have. E.g. ';henna/almond/lemon'; shampoo ??
I'm pretty sure they're fact. I remember hearing that they list the ingredients beginning with the one with the most amount in the product, and each ingredient after that becomes successively smaller in amount.
if it is labeled in the the ingredients list it HAS to be there legally if its not you can sue the crap out of them...first one one the list is the one thats in it the most decreasing as the list goes on the last one will be the least used ingredient... someone above me also said that to...
if it is in the ingredients list, it should be real.





but if it is in the title or description of the product, that is no promise.
