Exactly what is Your Budget?
Here's where some individuals come a cropper. You stroll into a hair supply store and see that advertisement of human hair for $9.99 for 20, 20 inches and you lose your mind. It's the deal of the century and you want in on it, right. But hang on for a 2nd - is this genuine hair or a "blend"? That's best they're now blending human with synthetic hair and calling it a blend mix or Mastermix, so take care when selecting your hair.
The extreme reverse is the hair bundles behind the counter. Oh these should be really special because they are keeping them safe, best. Well just because the price states $$89.99, $129, or even $149.99 (yes, some hair does cost that much - and for one bundle), doesn't imply that you are getting the very best value.
How Long Will It Last
For how long a weave will last depend upon you and the kind of hair you purchase. If you're searching for a cute design for a special celebration or something to last a few weeks, artificial or blended hair might not be a bad concept. If you're looking for something long term to possibly offer your hair a break or you do not like altering styles frequently; human hair is the only way to go.
Now the question of how long will it last primarily depends on how you care for your hair. Of course synthetic hair will not last as long as human hair, however if you don't preserve human hair it will not last either, and it doesn't matter how much you've invested in it.
