While in Antigua for Christmas, my cousin offered to retwist my hair for me. Who turns down a free retwist? Not me. I didn't actually plan on doing my hair, so I am brought was shampoo and coconut oil. She brought over black gel and beeswax to work with.
She mixed the two which resulted in a brown color. The final result was a pretty sticky mixture. The actual retwist was good, but but I wasn't a fan of the look of the mix in my hair. Take my work for it since I didn't take any pictures.
This retwist lasted just over three weeks. When I finally washed my hair, it took about four lathers to feel clean. That could be a combo of the amount of product and the fact that I hadn't made any shampoo in a while so the ratio in the bottle might have been a bit off.
Would I used beeswax again? Probably not, mainly due to the sticky feeling which took about a week to subside. Would I recommend it to some else? Why not? You need to try things out to figure out what works for you. Especially if it's for the free.
