Hello, Queen Of weaves here from http://www.queenofweave.blogspot.com - www.queenofweave.blogspot.com
To be it sounds like the hair is falling out due to over processing.
I recommend moisturizing the hair with oil or olive oil,wet the hair and make sure the hair is completely soaked in olive oil
do some detangling, and pute the curls in rods then pute in a walmart or plastic bag and microwave until its warm. leave it in the mixture and rods over night.
and the next day get shampoo mix with a little oil , and wash out the olive oil in COLD water.
I hope this helps.
Best of luck.
