Hi, If your mom has indeed such nice long hair, propose her to shampoo her hair and help her brush and dry it for her. You should even propose her to cut the (split) ends. But maximum 10 cm. You will certainly find out how much pleasure and satisfaction it will give to you, so that you realize that if she lose her hair you will lose all your pleasure, fun and satisfaction. You can even propose her to go a bit shorter so you will have the opportunity to cut it every month 5 to max. 10 cm. BUT never ever go shorter then hip lenght.
