How many bundles?

I had 6 bundles ordered and they placed in 130 strands. I ended up removing half of them, because it was simply 1) too heavy for my scalp 2) uncomfortable 3) unnatural looking, because I have fine hair. Now, it is much better and even with about 70 strands my hair looks gorgeous. Girls, please do research yourself before you end up shelling out the $$$$, because most stylists will not tell you the truth. Of course, there are horror stories--what else can happen when you have hundreds of bonds stuck to your fine hair. And do not keep them for longer than 3.5 months (4 at most), because the fine hair cannot take that weight for too long. I am glad that I had mine, but next time I am going to another person!
P.S. Make sure that she does not place bonds too close to your scalp--the bonds should swing more or less freely from the hair, otherwise it is both additional stress for the hair and some pain.
