i find that keeping my hair "relativley even" helps so much. i dont think hair necessarily has to be blunt all over but that most of the hairs in a given layer of the hair are around the same length.
i also think regular trims/dusts are the truth. even just the smallest bit makes a difference.its not only about keeping the split ends away, when the hair is more even it acts better overall.(there is probably some more convoluted explanation to this but essentially this is what happens
) going a year without a trim was one of the worse ideas ever. my upside down v shape is more apparent than ever.(mine is naturally occurring though since i have no hair in my nape)
i think the best hair cut for fine hair would be the bottom half blunt and the top half layered. so that way you can get volume and thickness.i cant wait to cut my hair this way!
