Is a lashlift haram? I am confused because there is no make up implied but it will make my lashes seem longer.

Here is the definition of a lashlift:
A lash lift is a technique for treating your own lashes – without applying false lashes (extensions) – in such a way that your natural lashes are curled, lifted and optionally tinted.

It is not haram in itself, and the wudhu would be valid as long as they don’t apply a tint on the lashes that blocks water from reaching them.
