Love Joico products. They've been around since forever and a half and are a favorite among pro stylists. The different conditioners are terrific and the Joico Joigel Firm gel is a staple for me because it works well without drying my hair out. K-pak helped restore curl to my hair after some damage from developer. Not sure it's a good idea to use K-pak as a regular conditioner because there's such a concentrated amount of protein in it. Better to use one of their other conditioners, all of which also contain a fair shot of protein (keratin).
