I dont know what to put for this, because I have always taken care of my hair. Meaning I deep condition once a week under a hood dryer, did this before coming to this forum, washed my hair once a week, and on that day of cleaning I would blow dry, press and flat iron. My hair still grew with that once a week kind of heat and only washing once a week. I put weaves here and there, and would wash once every two weeks with the weave. I also do an Aphogee treatment every 6 wks. I didnt do wet buns, wash every day or every three days, put the oils in my hair, and stick to crazy regimens, just the norm, and my hair continues to grow.
I switched up my regimen because I see my hair can have potential to grow faster and more healthy after the last time I damaged it.
So I think that even if I washed my hair once every two weeks it would still grow. I think I would be effortless, but it prob wouldnt grow as fast if I dont take extra care, idk
