Take a shower and shampoo as normal. I recommend staying in the shower for the application, as the water will likely not just stay on your hair. Coat the strands from root to tip in sections—going slowly. This is why I recommend a squeeze bottle with a cap—because you'll have more control. Let it sit for five to 10 minutes. If you don't want to stand in the shower for that length of time, you can put on a shower cap to make sure the rinse doesn't get elsewhere. We also encourage you to give yourself a scalp massage during this process, which can help improve circulation to the area and has been shown to aid with hair growth. Once done, rinse again in the shower, and top it with a conditioner if your strands run on the drier end.
