We invented the 2in1 to make great hair for men less complicated. Why take time out of your day to use both shampoo and conditioner when you don’t have to? With Pert, you can get ready faster and your hair will feel clean, smell fresh and look healthy in just one step. Pert offers six different options to meet your specific hair type or need. So How Does Pert Work? Pert uses a patented 2in1 formula. During the lather phase, the shampoo collects dirt and oil while the conditioner works on your hair to form a protective seal to provide strength, shine and protection against damage. Suggested Use: Instructions: For Best Results, Use At Least Twice A Week Or As Directed By A Doctor. Gently Massage Into Wet Hair, Lather and Rinse. Repeat If Desired.
