Hi, I had exactly the same problem and I can kick myself for putting on acrylic nails.
What i found really good is a product Biosculpture (you could get it done at any Nails Inc called 3 week manicure).
It's all natural and they dont do any harm to your nails, its a gel but all natural. I had that put on after i had my acrylic nails removed for it to grow out... and have to say I'm VERY pleased with the results! my nails are now stronger and splitting less!
Best thing I could have done for my nails!
