I’ve washed my hair with body wash and it works fine.
I don’t usually have body wash in the shower but sometimes I’ll take it from the hotel when I’m on vacation, and I’ll use that if it has a nice scent. Other than that, if someone gives me some I’ll use it and enjoy it but it’s not something I typically purchase.
There was a time when I had some body wash and I was using it for about a month, washing my hair with it. When I went to the hairdresser, he commented that my hair was soft and in good condition. I told him I’ve been using body wash on it. He indicated that it’s not a bad thing to use body wash in place of shampoo. I guess if it has stuff to make your skin soft, that works just as well to condition your hair.
