There have been several posts on various nail treatments in this forum, and I have tried them all at one time or another. So I am throwing in my observations and experiences with these. I build guitars, so my nails are constantly getting abused by contact with planes, chisels, clamps, etc. Without reinforcement, I would be frequently breaking nails, and I like to play guitars as much as I like to build them. Hope this useful for those that are considering some form of nail reinforcement.
Acrylic powder: I had this stuff applied by a nail tech every couple weeks for a year or so, then started doing my own. The liquid that dissolves the powder smells bad, but the results are OK. The sound is acceptable as long as you have actual nail in contact with the string, but if the acrylic extends beyond the nail I find the tonal qualities to be marginal. The major downside is that when the material starts to lift off the nail bed, and that will happen given enough time, it takes nail material with it. When this happens more than once, the nail bed becomes totally messed up and thin. Overall, I rate this as my least favorite approach.
UV cured gel: After using acrylic for a year and a half, I bough a UV lamp and the gel in hopes that the material would reinforce without destroying the nail bed. This stuff works pretty well. It is much easier to apply than acrylic. However, it too will lift off eventually and remove some nail with it. Not nearly as damaging as acrylic, but not great. As with acrylic, the sound is OK as long as actual nail contacts the strings.
Silk Wrap: After using UV gel for 2 years, I tried silk wraps. I do it myself. This is nothing more than thin, tight-weave fabric that you cut to shape and peel off a paper backing. Once applied to the nail, you apply a drop or two of CA glue (super glue) that soaks through the material and secures it to the nail. I use at least two layers, covering the top 1/2 of the nail. Let the glue set between layers. A light sanding and then a couple coats of clear polish and you are in business. (Miracle Nail Hardener from Sally's is the best that I have found as it does not chip off). I have never had a wrap lift off in over two years. When the wrap grows out to near the end of the nail, you can remove the wrap by rubbing with a paper towel dampened with acetone, The nail bed will be as good as when you applied it - no damage. Shape and polish the ends with a board and 2000+ grit sandpaper.
Overall, I highly recommend silk wraps. They look completely natural, are thin but incredibly strong, sound good, and won't destroy your nail bed.
