What routine helps reduce frizz and define waves for my wavy hair?

[Tyler54]

I’ve been trying to get my hair to look less frizzy and more defined, but my current routine just leaves it feeling heavy and greasy by the end of the day. I’m not sure if I’m using the wrong products or if I’m applying them incorrectly for my wavy hair type.

I tried a lightweight leave-in and a pea-sized gel, scrunched in while damp and diffused on low. Frizz was better, but the roots still felt weighed and by the end of the day it looked shiny and greasy.

I started skipping shampoo every day, went gentler with cleansers, and conditioned mainly mid-lengths. The frizz would creep back by afternoon and the whole thing felt stringy, so I wondered if the issue was buildup more than anything else.

There was a week I swore by a silicone-heavy serum, thinking sleek = defined. Morning it looked decent, by lunch the hair felt heavy and the scalp oiliness showed up, so I dropped that one fast.

Do you think humidity or porosity is the real problem here more than the products?
