Questions about a human hair braclet of all things

I've heard of jewelry and bracelets made from human hair before, but I have no actual experience with them. I know they were popular during the 18th (maybe 19th) century, but a lot of people have never even heard of them in these modern times. I don't ever intend to make such a thing or wear one, but I'm thinking of using one in my story. The tale itself is set in a dystopian future Earth where most of humanity has been enslaved by a malevolent race of aliens. Anyway one of the characters had a twin sister who was extremely close to her, but who unfortunately passed away a number of years before the events of the story (I'm thinking maybe 5-10 years, but I haven't specified an amount of time). I had this idea that the character in question would wear a braided bracelet made of her sister's hair in order to honor the memory of her sibling.

I know this is a rather odd request, but I have a faint hope that someone might have some practical knowledge regarding the subject or in the very least hair in general. I grew frustrated with google and was unable to find the answer I was looking for. I have two questions the first being: After being separated from the head for a long period of time does hair become brittle or deteriorate? And secondly, Would a bracelet made from human hair require any special care or maintenance?

Thanks in advanced! :D
