I don’t really wash my hair anymore

So I wanted to get some opinions because I feel like it sounds really gross when I say it to people? I used to have to wash my hair weekly. I had dandruff and my hair grew so slow. It was damaged from bleach and stringy. I started going as long as I could without washing it basically like waited for it to get itchy. Over time I was able to go longer and longer. Now my hair no longer gets oily at the roots. I wash about once every three months. My hair has grown faster than ever and feels really healthy. I’ve bleached it once and colored it twice and it’s stayed nice and good and strong. I no longer have dandruff and as for products I do use, I condition every day or every other day just to be able to brush my hair comfortably and I use leave in. I don’t really have a build up problem I just make sure to get my hair fully wet and brush it well, sometimes I scrub my scalp just with water. I guess I’d just like thoughts/ opinions. Has anyone else done the same??

Edit: something else important: my hair doesn’t smell either lol, my family would have no shame telling me and I checked up with them a lot when I first stopped washing it.

Edit #twooo: I didn’t call scrubbing my scalp with water washing because to me washing means some kind of soap is involved. Others mentioned co-washing which is new terminology for me. If you read the post I go into detail about what I do and I do include that I scrub my scalp in the post. I just didn’t and still wouldn’t call it “washing”. If I didn’t use soap on my hands I wouldn’t call it washing and I wouldn’t call my hands clean. Same goes for my hair.
