Candis asked this question because she has natural hair but her braider suggested a relaxer will ensure a flatter sew in so I hope this video helps you!
1st Answer: Do you watch my videos?!
I have done all of my sew in tutorials with natural hair and my install is very flat!
2nd Answer: Your braider suggested this for his/or her personal reasons because my natural hair does not affect a flawless install.
*Tip* Lightly mist your hair before manipulating it to make it a little more malleable than it is when dry and to also stop much shrinkage from happening in the process.
3rd Reason: Find another stylist if they cannot do your hair in its natural state!
Thanks For Watching!
