As far as answers go — I think it might work less well only for people with reeeally thin hair that can be easily be weighed down otherwise it’s really just healthier for your hair especially if it’s longer. If your hair is thick or dry it’s a godsend. Boars bristle brush is key — I’ve been told (not sure if this is true) that it’s really the only type of brush capable of moving oil from the roots through the ends of your hair so you’ll want to get into the habit of brushing with one of those every day. Really once the oil is away from the immediate scalp area your hair doesn’t look greasy. I “co-wash” with davines conditioner and hot water really helps to move the oil down the shaft. There is a thing called scritching but I find it annoying and I’m lazy so usually hot water is enough to move what needs to be moved. Conditioners still have a small amount of detergent in them but really I mostly do it for the smell/moisture and it makes my hair a little easier to manage. My hair type is very thick/dry/heavily processed. The first few weeks was kind of miserable and I thought I had a hair type that it just wouldn’t work for but once I got through that I’ve never looked back. I’m not a fucking weirdo about it though and every once and awhile it’s nice to wash with shampoo if the mood strikes but I save a lot of money by not needing to buy it anymore.
