Navy blue? I did a casual search and it could be a Faberge Shampoo. They did a very dark blue one promoted by the 70s blonde poster girl Farrah Fawcett.
Then a bit later I can see more regular blue ones from Faberge with no association with Fawcet, a bit later than the 70s but I think Faberge did continue with similar types of shampoo.
