Why does a fingernail grow crooked?

A fingernail can grow crooked due to various factors, including improper nail trimming, injury to the nail bed, or underlying health conditions such as fungal infections or psoriasis. Genetics may also play a role, as some individuals are predisposed to irregular nail growth. Additionally, pressure from tight shoes or frequent trauma to the fingers can contribute to a nail growing out of alignment. Maintaining proper nail care and addressing any underlying issues can help improve nail growth.
