White lines on nails

[Worriedmama]

I just noticed some of my nails have the little white spots/ lines on them. Most online sources say mail trauma is to blame. I have pretty long nails and tend to hit my hands a lot and sometimes my mail will bend back (which hurts like a b). Anyone else have these spots on their nails?

Yes, I get them periodically, as do most people I know. Trauma is definitely a leading cause. No biggie.

i dont get them so much now but i used to all the time. my mum used to tell me it was the keratin moving up into the top of the nail but thinking about it that doesnt make much sense. more likely what you were saying abt knocking ur nails lol, but nothin to worry abt its very common
