I had the same problem with my lashes being flat as hell. I finally figured years ago that no regular mascara actually works on me right no matter what brand it is. I switched to waterproof mascara which solved all my problems. I first place my curler on the base of the lashes and press but not too hard and work my way out pressing the curler on the whole length of the lash, if that makes any sense. I do this several times so it looks natural. I then start with any waterproof mascara at the base and wiggle it a little and work the brush to the tip. I wait for the mascara to dry and then put a brush comb through it to separate the lashes and then reapply mascara. I keep doing this until I'm satisfied with the thickness.
