For this Reason....
I gave the item 4 stars because even though the hair is nice, soft and easy to manage, it is not human hair. Its a mix (burn test) and the integrity of the hair changed with curling iron heat. It does not hold curls, so if you like the straight look only, this if for you. I added the hair to human hair unit and it matched. 1B is closer to a #2 in color. I do not often do reviews, but buyers must beware this is not 100 human hair. The bundles are thin weft so order more than one 3-unit bundle for thickness. It is good hair. The 4-star is for incorrect advertisement. I would return but i used one of the bundles. I am a human hair girl.
Rating: 4 stars
