Depending on the level of dirty your hair is. If you have normal to oily hair, especially longer thicker hair than yes. I work at a salon and for those with particularly dirty or just thick long hair we do shampoo twice. If you are unsure shampoo once with a regular amount and see how sudsy your soap gets. If there is little suds you should work it in rinse and then shampoo again, notice the bubles? The cleaner the hair the more suds you will get
You should wash it regularly from now on and shampoo TWICE before applying conditioner. Reason why is when you shampoo once all that does is move dirt around but when you wash it twice it will cleanse your scalp. With conditioner apply gently and not to much focus on your ends not your scalp, avoid any oil treatments for your hair that you may have.
