I did some research recently on how to grow your hair as quickly and as strongly as possible. I watched a couple of videos and the one that came up often was brushing your upside down for 2+mins daily or even washing your hair upside down with cold water then quickly changing it to warm water while showering. It helps growing your hair because it increase your blood flow to your head. I’ve always washed my hair upside down with cold then warm water, this is because I have very thick hair and is difficult to rinse all the products I used and also because as a child my mother always taught me that rinsing your hair with warm then cold water( or the other way round) helps grow your hair. Any way, I have been brushing my hair upside down almost on a daily basis now and has helped my hair growth. If you suffer from any neck or back problems
(if you don’t you can still do this) I would advise you to lye on your bed and put your hair on the edge of the bed and just let your hair fall over the edge and lye there for like 2+mins.(image below is what I mean)
