Whether it's tap water, soft water, or hard water, our shampoo bars have proven effective in cleansing your hair. There are some adjustments you may need to make when dealing with hard water. Hard water contains mineral and metal deposits from pipes and processing plants, which can be detrimental to your hair and overall health. But fear not! Our shampoo bars can still work wonders in hard water. In hard water areas, you may need to use slightly more product and lather longer for thorough cleansing. Your skin and scalp absorb what you wash and rinse with! Cleaner, softer water ensures a healthier, easier washing experience with any products.
