Curls: To Trim or Not To Trim?

To trim or not to trim is the BIG question. And if so how, when, and what is the best method. Some people are faithful believers in trimming their ends, but is that the key to maintain long and healthy curls? Of course at some point a trim is needed, but perhaps the best technique is a preventative technique. If we curly heads can do a better job of taking care of and protecting the ends of our curls maybe a trim is not needed as often. Things to try: Sleeping with hair tied in a satin bonnet, sleep on satin pillow cases, keep hair moisturized (with special attention to the ends,) seal the ends of the hair with shea butter, oils etc, and you can never go wrong with a protective hairstyle (wearing hair in a style to protect the ends from rubbing against clothing and other things.) Also, what about the search and destroy method? This allows you to maintain more length, because each strand of hair is being searched for damaged ends to cut off. This also can be very time consuming. Some even like to clip the ends of their hair while wearing two- strand twist. I currently do my best to protect and take care of my ends, while getting a trim maybe twice a year. This allows me to retain much of my length and each time I can see a difference in growth. What do you like to do and how do you like to do it?
