Where can I get hair extensions on LI or manhattan?

I live in Manhattan but come out to LI often. Does anyone know of a good place to get extensions in Manhattan or on LI.

I am in Islip and Garden city areas often but would be willing to travel.

Any info is appreciated

My colorist left the bleach on too long (and applied it over hair already bleached) and it burned badly!! I need to add a little thickness to it.

I was thinking of the clip on ones but don't know where to get those either. I think I'd prefer the ones that last a while.

Any help is really appreciated

I can't tell you where to go, but wherever it is...make sure you talk to someone who has firsthand knowledge...they've had them and were happy with them. & I would check the BBB also for the name of the salon.

My cousin had some of her hair fall out from getting extensions at a shop in NJ, and it ruined the hair she had...she had to cut it short after.

Good Luck!
