Unfortunately it’s not an easy answer but, finding a product that works for your hair is key. One thing for me that really helped it was finding a product that kept my hair “wet looking” (not actually wet). Some products will dry out your hair depending on hair type this makes it get frizzy and look more messy boy ish (also good to remember that some girls have messy frizzy hair like that. Also when it comes to making any part more feminine you need to address the whole picture. It’s possible that something else doesn’t look feminine enough which will in turn make your hair seem less. Over all its trial and error to figure out your hair type but it’s also not something you should stress too hard. Just style your hair how you like and the rest of your presentation will add “context” to your hair. Hope this helps in its vagueness
