Happy hour is designed to be super deep cleansing, almost a clarifying shampoo. Would be safe for extensions but you'd wanna get some good conditioner on there too. (I'm assuming you have real hair for extensions :) if not thought wouldn't be good for them.

If your extensions are human hair extensions, yes.
