(I posted this on "oily skin" but it wasn't really the right topic so i'm posting it here again)

I'm a 16 year old girl who has been suffering from mild-moderate acne for around a year (I know it isn't that long and that it's completely normal to have acne as a teenager because hormones but it is seriously wrecking my self-esteem). Around a year or so ago, my skin was completely fine. It was slightly oily but I suppose that is normal and I had a pimple or two on my face every now and then from eating greasy/oily foods or because of hormonal factors. I didn't use any facial cleansers and I only washed my face with water. My face and pimples were manageable back then.

I forgot when it was but I started using a clean and clear facial wash. It didn't cause any severe breakouts or anything but it didn't particularly help either. When school started my face started breaking out really bad, especially on my forehead. I've always had a slightly oily t-zone (thus causing it to be pimple-prone) and my mother suffered from severe acne back then (genetics). My pores started clogging up and I had big red pimples all over my forehead

I'm not sure why i started breaking out. Forehead acne is caused by an unhealthy diet (i eat pretty healthy), lack of water (i drink LOTS of water), build up of toxins, lack of exercise (I run/hike daily) and stress. It might've been stress but it kept on getting worse. There was a phase when I tried every single DIY acne treatments like oatmeal masks, tomato masks, lemon juice, ice cubes, etc. IT ALL DIDN'T WORK FOR ME. I started using St. Ives apricot exfoliator (with salicylic acid) and clean and clear oil control face washes for almost a year and nothing really worked. Sometimes my forehead would get better but it always gets worse again no matter how hard I try.

However, the thing about my forehead acne/pimples is that I'm not sure what it exactly is. I have a lot of clogged pores that look terrible in the light and make my forehead look super bumpy. These clogged pores turn into whiteheads. However, it's itchy (it's itching right now), thus causing me to wonder whether or not it's Pityrosporum Folliculitis. Does anyone know what Pityrosporum Folliculitis is meant to look like? Do I have Pityrosporum Folliculitis?

I've recently started abandoning my face washes because I realized that it all started getting worse when I washed my face with cleansers. I started washing my face with only water. I started this a few days ago. In the first few days, it seemed to start working, but now my forehead is breaking out with tons of ugly whiteheads (probably because of my period). if it is Pityrosporum Folliculitis, I'm not sure whether "washing my face with only water" will work because it is after all a yeast infection. I've heard that Nizoral shampoos or even head and shoulders work, but I'm scared it will cause my forehead to break out like mad. I've attached several pictures of my situation (it's what my forehead is like currently, not the worse but it's all I've got right now.

Last night, I couldn't stand the itchiness and washed my face with head and shoulders shampoo. It doesn't seem to work (not directly, at least)

Can someone please tell me if:

1. My acne is Pityrosporum Folliculitis or not? It's itchy but apart from that I'm not sure because it doesn't look as extreme as the photos on google

2. If so, should i continue with my "washing face with only water" regime?

3. Will Nizoral shampoo or head and shoulders help? How do I apply it properly?

Has anyone else been in a similar position as I am in right now?

Thank you so so much! My forehead is totally wrecking with my self-esteem it's terrible
