I think everyone else here has pretty much covered it, but if you were buffing your nails with 180 grit, then you likely (and I'm sure completely inadvertently) filed down the layers of your natural nails and thinned them out. The 180 grit is used ONLY to break the seal of the top coat during soak-off - and that should still be done with a light touch. If you need to buff your nails prior to putting on the SOG foundation, you need to use a fine grit file/buffer and lightly remove the shine. I use to use 180 grit to smooth/shape my acrylics - that's just way to coarse to use directly on a natural nail. At this point, lay off the file, baby your nails with plenty of moisturizer, and maybe use something like Structure to help give them some strength. You're just going to have to keep them short and let the damage grow out.
GORGEOUS!!! I never had the talent for one-stroke painting tho I love it.
Make sure it's a fine grit - 240 or above. Some "box" buffers come in a course grit as well.
Thanks so much for your advice! This forum is so great.. Much better than YouTube videos haha! I blame "thenailteacher" for my mistakes! If you watch her video on gelish she says to use the 100/180 grit buffer and she even says "use the coarse side of the block" !!!! Not much of a nail teacher haha but thanks again!!! I will definitely stay away from the buffing and stay patient... As long as I can have my nails nicely painted in happy, and it takes away the pain and sensitivity of the weak nails
