Hi again, and thanks for your reply with clarification.
Yes, having your very thick hair thinned out is good, a couple of times a year (or whatever your stylist recommends), because it decreases the weight of the hair which can contribute to stress on the hair, weakening it and having hair fall out more often.
Split ends are not healthy and whenever you get a haircut or have your hair trimmed, it's good, because the split ends are being cut off.
If you use a 'restorative' shampoo and conditioner like Pantene Pro V, for example, it will help prevent split ends. Also keep in mind that if you blow dry your hair, the heat is also damaging, so don't use the highest setting and also spray on a product that helps protect your hair against damage from the heat, before you blow it dry.
