Has anyone used Blondies in Selden for the Keratin Straightening? what was your experience? Whould you recommend it or any other plance?

I'm torn between going to Blondies because it is close to my home. or going to Hair Club IB in Flushing.

Blondies uses the Peter Copola Keratin Treatment and Hair Club IB uses the Hair go Straight product

any information would be greatly appreciated.

TIA
