thanks, I know the price it will cost me. I will try one soon and see for myself. its easy to check if hair cuticle as been striped just sqeeze couple hair between finger and slide back and fort.
When sliding your finger on the hair shaft in the direction of the scalp you should feel a resistence, small but alway there, tryed on many hair. and the old hair system did not have any resistance in both direction. so it was acid bathed. but its not from the internet.

I when I order my piece and get it I will provide great quality pictures for you all to see the quality of it, I got a small photo studio
