i have wavy/curly hair and when i want it to wave i use toni & guy soft curl cream - which is the shit - it gives nice shape but is a really nice light texture
or for when i want more defined curls or longer hold (i usually wash my hair every other day but if i know i am not going to be, i use heavier product so it doesnt turn into a rat nest) i use their twist it curl balm which is also super amazing
i have tried sooo many other things over the years and these shit all over them. plus they smell nice. if you ever wear your hair straight, i can also recommend yjr t&g texture paste for good hold & matte finish, cause i find products that make yr hair too soft and shiny unmanageable
you can get little travel size versions of all of these in boots, so you can try them and see if they work for you
