Does the Alterna 10 hair care line come with a seal to let you know if it has been opened?

I recently purchased the Alterna 10 shampoo and conditioner over Amazon and have been a little reluctant to try them out because I'm unsure if it has been tampered with or not. Does anyone use Alterna 10 and is there a security seal on them or not? Thank you! I would hate to throw my money down the drain because of this :(
