MY PERSONAL REVIEW:
This is much better than the synthetic ones as it looks very natural and blends in perfectly into your hair. Looks awesome possum on camera too! The drawback about most synthetic bangs is that it cannot be dyed/ironed and it is veyr shiny when photo is taken and hence shows up as synthetic/fake. This does not happen with human hair bangs as it appears to look like your own hair, very natural. The price is higher due to quality and the fact that it is made of human hair. it is recommended for those who intend to wear this bangs on a regular basis. Also we do not have the seamless human hair bangs yet so wearing this on requires one to wear a hairband to conceal it. I like to wear the kanekalon (synthetic) hair braid hair bands to conceal it with a natural touch. any simple hair band will do the trick.

My Personal Review:
Honestly this stuff looks like a piece of crap at first sight or even at second sight when you look at it alone.  But i gave it a try anyway and was surprised that it actually looks great when it's worn on one's hair. This bun piece is made scrunchie style and it is pretty easy to use - just loop it over your hair bun/ponytail/half-do. if it is too loose just place 2 bobby pins criss crossed to secure it in place. If your hair's length is below your shoulders these would be easier to use as you'd have enough hair to gather up a simple bun which would fit the the hair piece when it is looped over. For those with less dense hair, it can still be used but I'd advise you to use bobby pins to pin the bun piece in place to your hair so it doesn't fall out.
This stuff may get messed up easily as with all kanekalon products, so id advise one to take good care of it and try not to get it messed up yeah. I've seen similar product like this in accesorry stores however, those were pretty plasticky and a tad too shiny and therefore looked fake. This one is made of kanekalon and it looks pretty close to real human hair.I do not recommend this for those with hair length above the shoulders, unless you'd like to use it for half-dos. Half-dos with hair down will only look nice if the ends of one's hair is curled yeah.

Warning: do not heat/iron this item yeah as it is made of kanekalon which is not heat resistant.
