After being natural for 2.5 years, I decided to have my hair professionally texturized (ORS) twice (December - full hair, and March - touch up). While I love the look, I now have a HUGE area of hair breakage in the middle left side
. My hair is between APL and BSL. The breakage area is 1/2 inch in length.
What could have caused this, how can I prevent this from happening again, and how should I correct it? Please help.
