I am thinking about getting a sew in to grow my hair. I am all natural 4b hair (did my last BC two weeks ago) that is neck length straightened. I never had a weave only braids 12 years ago where the edges of my hair thinned. Because of my braid experience I have been reluctant to do anything different to my hair but hot comb it every two weeks. I talked to a hair stylist and read a little about it online. I hear so any people say that they were able to grow their hair long and retain it. I would appreciate any advice and for those who wear or have worn a sew in that has helped grow your hair please chime in.
