Maintenance is key. I dont do mani/pedis but i do moisturise my hands daily and have a regular trim. You would think it does the opposite cutting them, but it means they arent going frail or having a chip turn into a bigger nail getting broken because i left it.

Essie almond cuticle oil was a game changer for me! And a lush, thick hand lotion. L’occitane hand lotion if you want to splurge, or the pink bottle Vaseline Intensive hand lotion if you want a really good supermarket option

Oh I hope there’s lots a replies to this one. My nails are getting to a certain length, not long, and they split and break. So frustrating

I agree with the poster below. Try some of the skin and nails vitamins. There are various brands available.
Failing that you might just have to stick with the falsies.
I do think that sometimes its just genetics. I have always had long and strong nails and get that from my mother.

B vitamins! A strong protective nail coat and some quality cuticle oil
