I got my hair sew in weave last month, and have been using ever straight Brazilian keratin shampoo as advised by the attendant at the salon, however, I have noticed that lately, my hair is getting frizzy at the end, and they take a good deal of time to get de tangle! I wanted to know whether it is because of the shampoo that I am using, or is it a problem with the hair weaves that I got done last month! I would like to know if I should switch my shampoo, which is by the way a non-sulfate shampoo as told to me my the attendant there, or I should get Sensational hair Remi next week! I would be really thankful to you guys for an appropriate advice!
