Hi Bellan
youve probably had your new style by now but I have just found your post, years of H/D have proven to me that the more weight or length hair has the straighter it will be, ie gravity, likewise, remove the weight, layers or chipping in thinning etc, is to add volume ie width bulk,few exceptions are really fine/thin hair which can look sparse if too much is removed, how did it turn out, curious to know how they handled the shape, enjoy your new found curls, it happens often just needs practice
