You sure can, honey. It's just named baby shampoo because it won't cause tears in a baby's eyes if it gets into them. Feel free to use it if you like it!!
Of course you can! It's just said to be for babies but it doesn't say grown ups can't use it! You don't need to be shy using it because in the world people still use things they aren't supposed to but Johnson baby shampoo, you can use it so what's the big deal! Go ahead and fulfill your wish!
