African hair, keratin straightening and hair extension

[Dimag]

Hi 
I am a black woman with of course African frizzy hair. I am a total fan of Brazilian keratin treatment to straighten my hair. In Paris before arriving to Singapore, i did this brazilian straightenig in my hair salon and i would like continue here. 
Moreover, i have hair cold fusion hair extensions ( this method uses no heat, no glue and no heat tool to bond extensions )to have more volume and  length  . My extensions are 100% human Remy hair extensions.

So somebody does it know if there is in Singapore a good hairdresser to perform the same keratin treatment and to apply black hair extensions according to cold fusion technique and to remove my previous cold hair extensions
Thank for you reply, that is very urgent
