What to consider when buying shampoo bars
Always think about your hair type. The best shampoo bar known for its scent or affordability means nothing if the formula is not right for your specific hair type. Most shampoo bars have fewer ingredients, so it’s easy to spot anything that might be especially great or especially bad for curly, thick, thin or color-treated hair.
After you decide to make the switch, give your hair some time to adjust. Switching formulas and testing new products takes time. Only hit the refund button or search for another brand after allowing your locks to adjust and adapt to the change.

FAQ
Are shampoo bars good for your hair?
Shampoo bars often replace preservatives, chemicals, sulfates and dyes with natural ingredients, which could be good for your hair since those ingredients are so harsh. And going the shampoo bar route is just one of the natural beauty product swaps you should try.
Are shampoo bars good for curly hair?
Again, it’s all about the ingredients. Shampoo bars specifically formulated for curly hair will do the trick. Seeing as most shampoo bars already lack harsh sulfates and drying alcohols, many could be compatible with curly hair types.
How often should you wash your hair with a shampoo bar?
You can use a shampoo bar to wash your hair as often as you wash with regular shampoo. Some reviewers claim that after continuously using a shampoo bar, they can actually wash their hair less often. How often you wash your hair generally depends on your hair type.
