I put mayo in my hair once a month. It makes it extra silky and strong and it it helps not make my hair too thick, AKA makes it lay more nicely. What about you? Have you tried it? All I do is put a towel around me then put just enough mayo to cover roots to end, but not a super thick slather of it, just enough to saturate it. I enjoy my routine, I can't guarantee nothing but it is a fun thing to do when you've got nothing better to do, LOL.
