In the Name of Allah, Most Gracious, Most Merciful.
All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.
In this fatwa:
Answering your question, the General Iftaa’ Department in Jordan, states the following:
You aren’t obliged to renew your wudu (ablution) nor to wash your hands according to your case whether cutting nails was done before or after making wudu. The same ruling applies to trimming the hair, since they won’t invalidate wudu. However, if you want to wash your hands for personal hygiene, then it’s up to you.
Almighty Allah knows best.
