Q: What do I do if I get cracked/ flaky nails?
A: The key is to hydrate and add oils back into the nails. Solar oil is a great product to do this, but a good hand cream or cuticle oil will work as well; best to use after washing and thoroughly drying your hands to avoid them drying out. I wouldn't advise using a nail hardener or strengthener as in the long run this could have the opposite affect and make the cracking/ peeling worse. Always try and wear rubber gloves when washing up, doing gardening and using harsh chemicals.
If your nails don't improve with time there may be other reasons for it i.e. low levels of vitamin C, folic acid or certain proteins or iron deficiency, thyroid or kidney problems so best to seek medical advice.
