our beloved Prophet Muhammad sal Allaahu alayhi wasalam's hair was perfect, and beautiful. you have the right to keep it and cherish it etc. you can even keep it in a safe place insha Allaah but it shouldn't affect your worship insha Allaah.
Hadith - Muslim, Narrated Anas ibn Malik (r.a)
I saw when the Messenger of Allah sal Allaahu alayhi wasalam got his hair cut by the barber, his Companions came round him and they eagerly wanted that no hair should fall but in the hand of a person.
so the same way the sahabah treated the hair with alot of respect and they wanting to keep the hair, it is a good thing to do insha Allaah. the main point is that it shouldn't affect a persons worship insha Allaah.
wa Allaah u a'lam. (and Allaah subhanahu wa ta'aala knows best.)
wa Salaam o 'alykum warahmatulahi wabarakatuh.
