"Here comes a perfectly valid argument: To start with, everyone who is both a rare consumer of Pantene shampoo and an occasional purchaser of Herbal Essences shampoo is a frequent consumer of Tom's of Maine soap or a regular user of Mysore soap. Now, every frequent consumer of Tom's of Maine soap is neither a rare consumer of Pantene shampoo nor an occasional purchaser of Herbal Essences shampoo. We may conclude that everyone who is not both a rare consumer of Pantene shampoo and an occasional purchaser of Herbal Essences shampoo is however a regular user of Mysore soap."
Is the argument, given the explicitly stated premises, deductively valid or invalid?
Options:
- valid 
- invalid
