I only used 1.5 packs of hair as I did not make a lot of braids. I used the braiding method at the root because that is easier for me.
I curled the ends by wrapping strands of marley hair around a bunch of twists using the corkscrew method, dipped the ends in hot water and cut of the excess.
I now only keep extensions for a month as water will not be touching those babies. I will be using the same regimen that I am using. Check here for the regimen if you missed that post.
