well as my wife worked in giant factory in pi . the stuff they use was a giant secret and they burn all the ruined units so no one copys them. i have had real trouble with hair over the years drying. 90% dont have this problem some do. u can try nearly natraul from debbie as i think the stuff doesk. shampoo the NN then cond and rinse. i like the shampoo for helping a dead unit called purelogy nanoworworks in purple bottles about $20 a bottle,steep but makes hair real soft. sometimes to soft on a newer unit imo.
