This book gives great, detailed steps to taking care of your nails. I personally didn't learn much, but I have been doing my own nails for years and before that had regular appointments with professionals. I would have liked to see more tips to prevent smudges and such.
Definitely very informative. I feel pretty well-versed in nail health and care and I learned some interesting things, plus tips/tricks. Worth skimming,if you know a lot about nail health & care and reading thoroughly, if you have nail issues or are new to nail health & care.
