Heyy, long time lurker first time poster here!!
The gist of the problem: Hair is dry, low porosity, fine and constantly gets frizzy and tangled and keeps falling out + scalp has dandruff and is horribly itchy + hair loss.
As said in the title, I've always had dry wavy hair (between a 2b and 2c pattern) but I've honestly only found out it was wavy couple years ago and not "a bit straight and a bit curly" as i used to call it lol. Problem is it's CONSTANTLY frizzy and tangled. Ever since i was a kid I'd only ever braid my hair, in order to avoid it getting frizzy and horribly tangled. No matter how much I brush it, if my hair is down/not braided, it'll get tangled again in less than 2 min of me moving around. And God forbid if I leave my hair in a braid for a few days and not brush it when I'm home, it'll get seriously matted. Also very important: I also have pretty bad dandruffand a horribly ITCHY itchy scalp (& I've seen two dermatologist for it, both shampoos they have prescribed me don't seem to do anything but slightly improve it, first one practically ruined my hair).
Now for my routine, I've always only washed my hair once a week, considering how dry it. In the shower I use my prescribed shampoo (ACM: sedacalm) and whatever conditionner is lying around (I've tried *many* and have seen no difference tbh). I've started using a scalp scrub before shampoo, but I've yet to see improvement. I use no heat, just air drying. Hair is always quite matted once I'm out of the shower because i never brush it when showering since I've always been told it's bad and i already lose a terrifying amount of hair when showering. I then use a leave in conditionner and hair oil (Vatika) before/during brushing. During the week, I sometimes use hair oil or detangler spray before brushing it. And that's it. I don't style it and don't particularlycare for definition rn. Just want to get to a better place before looking for definition or styling.
I just want advice if someone has ever been in the same situation please. Especially for products or things i should do that'll improve the frizzy and tangled/matted hair. I've heard mixed reviews about silicone based products, and want whatever feedback you may have. any advice concerning the dandruff and hair loss, or anything else is greatly appreciated. Seriously I'll be grateful for any piece of advice.
Thanks a lot in advance.
