If you don’t even know where to begin, we broke down the full guide of what to consider when you are making your wash schedule. Seriously, there is no question or concern we left unanswered. The scalp is so important because if your scalp is showing signs of inflammation, it can lead to hair loss. “If buildup or irritation is really extreme, it can even pull the hair down because there’s so much inflammation around the hair follicle,” says board-certified dermatologist Adarsh Vijay Mudgil, M.D. “I love that these new shampoos are healthier for your hair, but the problem that many stylists are seeing now is that they are so gentle that people aren’t properly cleaning their scalps,” says Reslan. “If you want to stick with your low-lather shampoo, you absolutely should, but you might need to add in another wash day or do a weekly clarifying shampoo.” “For many people like this, washing the hair every day is nonnegotiable: They just have to do it,” says Reslan. She recommends switching to a really gentle, moisturizing shampoo in this case. This likely means bringing your own shampoo to the gym or studio—don’t trust the generic shampoos they have in locker rooms, as they likely contain sulfates and cheap drying ingredients. Some days, you may even consider just rinsing your hair with water.
