Frequently Asked Questions

Are shampoo bars cruelty-free, vegan, sustainable, or free of palm oil?

Though shampoo bars are typically more environmentally friendly due to their reduced packaging, it can’t be assumed that every bar will meet your standards. It’s important to check each bar’s ingredients and specifications to ensure that your purchase aligns with your ethics.

Do I still need to use a conditioner?

As is true with most things, the answer will be different for everybody. However, there are certainly a few reasons people are less likely to need a conditioner when using a shampoo bar. These products tend to use high-quality ingredients, including natural oils, which means they’re less likely to strip away your hair’s natural moisture the way that chemical shampoos tend to do. If you feel like shampooing without conditioner might work for you, it might be worth giving it a try.
