Wavy hair typically needs a shampoo that's hydrating and lightweight. Look for formulas that are sulfate-free to avoid stripping natural oils and contain moisturizing ingredients like shea butter or aloe vera.

Fine wavy hair benefits from a volumizing and clarifying shampoo that won't weigh it down. Choose lightweight, sulfate-free formulas that remove build-up without overdrying, allowing waves to maintain their bounce.

Several brands cater to wavy hair, including Ouidad, DevaCurl (though some have reformulated), and SheaMoisture. Look for brands specifically designed for curly or wavy hair and read reviews to find products that suit your hair's specific needs.

2A waves are loose and stretched-out, forming a gentle S-shape with the hair lying close to the head. 2B waves are more defined and begin forming closer to the scalp, creating a more pronounced S-shape with some potential for frizz.
