Honorable MentionsPhotograph: Nena FarrellBeachwaver Co. Blow-Drying Hair Brush for $189: This cute blow-dry brush has a set of attachments that includes a diffuser. It’s a solid choice if you want both a blow-dry brush and a diffuser, but there are cheaper options if you don’t want the blow-dry brush included. Maybe you want to dry your hair fully, or maybe you want to take it to 80 percent. Maybe you want a leave-in, a curl gel, and a hair oil, or maybe you just need a little heat protectant. —Kat MerckDavines This Is a Curl Gel Oil for $32: This gentle curl gel oil has been fantastic for my fine hair, helping my curls form and keeping them moisturized without weighing them down or making my hair crunchy.
