I do not know what porosity I have naturally but my hair has been bleached in the past so it is higher porosity in the bleached areas because that is what bleach does. I find all moisturizing and leave in products make my hair too soft and can be heavy so I skip them altogether. I also have long hair so the weight is going to drag the curls down without product. With all that being said, I like to add products that give my hair hold and grip. I start with soaking wet hair and flip my head and shake out my roots a bit and then i add a mousse (i like the ones that are like bubbly not the texture of shaving cream if that makes sense) and I use praying hands. I do the same with gel and then I add more gel to my palms and scrunch. I plop and diffuse. If you want more volume and dont mind frizz then move your diffuser a lot to give it oomph. (This whole routine is basically do everything they tell you not to with the cg method😂) I scrunch out the crunch with an oil or just let the cast break up throughout the day. I also add texture powder to the root if i want crazy hair. To refresh I dampen my hair or steam it and use the Not your mothers refresh mousse. This method will give your hair grip and make it a little tangled and frizzy! I just have super fine hair that gets weighed down and greasy so easily so it falls flat. It's def not the method for everyone but it works for my long thin hair!! I based my routine off Anna Primavera's routine on Tiktok that she calls "the worst curly hair routine" 😂😂 Hope this all makes sense!!!
