All You Need to Know About Buying Sulfate-Free Conditioner Bars
Frequently Asked Questions (FAQs)
Typically made without sulfates and other harsh detergents that are common in liquid formulas, shampoo bars are also lauded for being gentler on the hair and many are very hydrating, too.
"Those with shorter, straighter hair can apply the product directly onto their head and scalp." Then, once you finish washing, rinse your hair clean per usual. Depending on the shampoo bar brand, you may no longer need to use as much conditioner after washing.
What happens when you switch to a shampoo bar? Most shampoo bars have clean formulas that don't contain sulfates or other cleansing agents typically found in traditional shampoos. If you're switching to a shampoo bar — or any sulfate free, “clean” formula — you may find that there's a bit of an adjustment period.
Unlike regular liquid or cream conditioners, conditioner bars are totally solid and aren't housed in plastic bottles. Instead, they're often packaged in sustainable, compostable, or biodegradable materials, making them a much more eco-friendly option than conventional conditioners.
