I thought this would be a good idea because the nail polish threads are all about posting colours, identifying colours and brands (or close matches) and posting photos of new nail polishes from people's favourite brands. Whenever anyone asks for help with something else to do with nails or nail polish, no one replies and only more pictures are posted. This is why I wanted to make this thread: a place specifically for advice on nails and nail polish that is not to do with colours. So this excludes questions such as, 'Which brand carries a nail polish colour like this?' since those are covered by the nail polish threads. If anyone is looking for advice, wants to help others or feels they have found a great tool/treatment/something else that's worth sharing with everyone, please feel free to post it here.
