I can no longer get Veralac which was the only thing that kept my nails strong so I resorted to a less natural method. I always keep my nails quite short-- to just beyond my fingertips, but they got so bad I could not tolerate even that. I began covering just the tips-- the part that extends beyond the tips witg brush on superglue. I buy KISS brand nail glue that comes with a brush. The trick is brushing on a thin layer and making sure not to touch my nails until I am sure it is dry. It is good to put it on while doing something like watching TV, so I am distracted and don't start touching my nails. It is just barely visible. There is just a slight shine to the very tips of my fingernails. I figure since I put the glue just on the very tips where the nail is not touching the flesh, the chance of allergies is small, and also, since just the tips get glue, and since I never use remover-- just gradually file off the part with glue on it, chances of major damage to my nails is slight. I actually have good and strong nails this way. Since the layer of glue is thin, I don't get the unpleasant clicking noise I sometimes get with fake or acrylic nails, if they are too thick. I have to reapply every week or two. At first I kept messing up and getting too thick a layer on, covering too mych of my nail, or touching my nails too soon to check if they were dry and getting an ugly although still usable surface. I have gotten much better with time.
