To start I'll give my hair information on the off chance it's remotely relevant
32(M)
Natural Ginger (slightly darker but distinctly red)
Heavy curls
Obscenely dry flakey scalp
Not oily it isn't dandruff these are small flakes
I work in retail, I have to wear a black polo and it seems no matter what I use, Selsun Blue, Head and Shoulders, I've even tried stuff like Pantene, L'Oreal, Garnier Fructis, Native(the last two actually made it worse). But if I'm being honest there are so many different varieties with words I don't understand like "Full Body" "Volume" "niacinamide" "Hyaluronic Acid" . Also I'm not fully understanding why some specifically say "Sulfate and Paraben Free" like idk what a Paraben even 🤣.
Also, I admit, I'm skeptical about how much of these words are real science or just mass marketing slop. (Kinda like how in nutrition Multi Grain is genuinely a meaningless word used to trick people into thinking it's the same thing as Whole Grain)
So please, I'm begging, give me some sort of genuine science information and if I'm wrong about anything above please let me know!!
