How many packs to use for the tree braids?

I am always asked how many packs of hair should be used for tree braids.

There are 2 answers to this question:

If you are going to use synthetic hair then I suggest that you use 3 packs of hair as the packs tend to tangle more, and there is less hair in the pack as compared with the human hair. Because synthetic hair is so much cheaper then human hair buying an additional pack will still be cheaper the getting human hair.

If you are going to get human hair by the ounce then you will need to buy 8 ounces which is usually 2 bundles. If you are going to your local beauty supply store and they sale it by the pack then you are going to want to get 2 packs and make sure they are at least 18inches long.

Please keep pointing your questions and I will do a better job of answering them for you all!
