I was retightened yesterday 1/7/08 by Angela, after 8wks. It took about 3hrs. It seems to be average. I asked about sls shampoo and was amazed to hear that she hadn't recieved her starter kits (shampoo etc) for her clients after months. Someone needs to get their act together. Fortunately, I don't rely on the sls shampoo. I use dreadhead hq shampoo. It's very effective. I also made a water based spritz (I hope to sell this alongside my coconut spritz), in which I mixed a little paul mitchell awapuhi moisture mist. Finally, my dry, thirsty locs have been quenched. My locs feel soft and moisturised.
