Hi , I do mainly the pre bonded hair extensions and these are very strong ,
these last for up to three months ,
then after three months they need taking out and re fitted again, this can be done over and over, but is all down to good quality hair.
I like the pre bonded because they already have the bond melted into the tops of them,
and because of this there there is far less chance of them shedding.
As long as you go to a trained and preferably experienced extensionist ,
or one that you have seen their work or been recommended ,
Make sure you see their certificates and check the hair is good quality hair and totally reusable.
It is very important to have any maintenance done in between ,
and follow all aftercare advice sheets given ,
you should be able to purchase a special brush, shampoo and conditioner off
your extensionist ,
Ps , any before and after pics ? :hug: good luck x
