Works well
Style: Shampoo, Size: 7 Ounce
This shampoo made a noticeable difference way faster than I expected. My scalp felt less itchy after just a couple uses and the flakes have improved a lot. I also like that it leaves my hair feeling clean instead of overly stripped. Definitely worth trying if other dandruff shampoos haven’t worked well for you.

Obliterates stubborn dandruff at the source, but grab a heavy conditioner.
Style: Shampoo, Size: 7 Ounce, Style: Shampoo, Size: 7 Ounce
If standard drugstore dandruff shampoos aren't working for you, this is the heavy artillery. I put a banana next to the bottle in the picture for scale, which reminds me—this stuff will literally stop your scalp from peeling like one. Instead of just washing away loose flakes, the active ingredient (Ketoconazole) actually kills the underlying fungal overgrowth that causes the itching and flaking in the first place. WHY IT'S A STAPLE: • It works incredibly fast. Most people see a massive reduction in severe flaking and scalp redness after just two or three uses. • It actually has a very clean, fresh scent, completely avoiding that awful medicinal or sulfur smell you get with coal tar shampoos. CRITICAL USAGE WARNING: • Because this is a serious, active treatment, it is incredibly drying to the actual hair shaft. If you use this without following up with a high-quality, heavy hydrating conditioner, your hair will dry out and feel like brittle straw. You only need to use it twice a week to maintain a clear scalp. THE BOTTOM LINE: The absolute undisputed heavyweight champion for eliminating stubborn dandruff, provided you pair it with a strong conditioner to protect your hair.

Showing some improvement, but still waiting for full results
Style: Shampoo, Size: 7 Ounce, Style: Shampoo, Size: 7 Ounce
After two weeks of using this shampoo as my doctor recommended (in courses, not for daily use), I can't say I've seen amazing results yet. The itching has reduced, and there is less redness on my scalp, but I can't say it has completely solved my scalp problems. I'll continue using it to see the final result. The price is fair, similar to other pharmacy shampoos. A definite plus is that it lathers very well, quickly cleans oily hair, and a little goes a long way. The scent is not strong, and it's actually pleasant to wash my hair with it.

Attention Suffers of Mild Seborrheic Dermatitis and/or Psoriasis!!
Style: Shampoo, Size: 7 Ounce
Alright, let preface this by saying, I am not a doctor or medical expert, I can only speak to the results, I myself have experienced. Back Story: So about 2 years ago, I started getting dry skin around my mouth, nose, eyebrows, and occasionally my ears and cheeks. It was pretty mild, so I never went to a dermatologist. However, before this time, never did I have to lotion my skin regularly, so this was a change for me. When this started happening, I used Aquaphor Healing Ointment (Advanced Therapy), and while it made me look greasy or like I was sweating for a couple hours, lol, it wore off enough, and would leave me looking normal the rest of the day. The only time my skin was really irritated was right after I would shave. However, dryness/peeling would get real bad if I did not at least lotion all those areas of my face after I showered. While I did some minor Googling about the issue, I was clearly too lazy to do anything about it, and the lotion solution sufficed for me. Dumb, I know. Anyways, fast forward to about 1.5 months ago. I started to notice a white growth under my left thumbnail that started to detach my nail from my nail bed. For some reason, this concerned me more than the dry skin on my face. So after Googling again, I found ti could be a problem with yeast growth under my nail. Then, I remembered reading that yeast growth could be causing my face problems. After connecting the dots, I decided to find a possible solution, to possibly kill two birds with one stone. After some searching, I stumbled onto Nizoral. After reading all the reviews, I was encouraged. I purchased this product and it has helped me tremendously. I could not be happier. It says to use it only every 3-4 days, which I say you should stick to, because I would use it on back to back days and it would seem to dry my skin out, but that could have been in my head. My Use: So, I know this is shampoo, but I almost treat it like liquid soap. I rub it on my skin/scalp and leave it there for 3-5 minutes. For my fingernail, I would lift it, since there was a gap and the nail was coming up. I put Nizarol directly in the ever so small opening between the nail and nail bed, and left it for 3-5 minutes. I am not sure if that was smart for the fingernail, but it worked for me. Results: TLDR: It worked everywhere, lol. Mouth/Upper Lip: This area was the worst of my dry skin issues. Like said, it was especially bad after shaving. Sometimes, my skin would be patchy red and inflamed after shaving, especially on the top of my chin and right below my lip. It would look gross for like an hour. In addition, when I did not shave, but did not lotion my skin, this area would eventually get pretty flaky before the end of the day. I also had issues with the corners of my mouth, especially after eating. My upper lip generally did not have any issues, but sometimes I would in very cold/dry weather. So, after using this product, I have seen a great deal of improvement. For the first time in almost 2 years, I do not have to lotion my face every single day. The patch below my lip still is not where I want it to be, but it is very much better. My skin feels dry after a shave, but now it does not look red or inflamed. It is getting better, and I think it will continue to get better. The corners of my mouth have issues if I do not lotion for 2 days or so, but they are much more minor to what they used to be. The minor issue above my lip is currently non-existent, however, we have not had any cold weather yet. This was the most noticeable problem I had with my dry/flaky/peeling skin, and I am happy to say, Nizarol has worked wonders. I now can use regular lotion instead of Aquaphor, which I still adore. Eyebrows: This was my second worse area, and I say eyebrows, but it was actually the area in between my eyebrows would flake worse than my eyebrows. I rub Nizarol into my eyebrows, in between them, and around my eye sockets. Nizarol has pretty much cleared up this issue, and I am thrilled Nizarol has basically eliminated the second worst dry area on my face. If I do not use lotion for several days, it does flake, but in a very minor way. Side note: be careful around your eyes, it burns pretty good if you get the shampoo runoff in your eye, lol. Nose/Nostrils: This was my third worst area. I would have dry skin on the sides of my nose, the point of my nose, and even on the inside of my nostrils! First off, putting Nizarol in your nostrils may not be safe. If you do do it, don't huff the Nizarol when it is in your nostrils, breath through your mouth. My nose area has improved, but is now more of an issue than my eyebrows. Still it is much better, and I can go a couple days without using lotion. It is also more of the inside of the nostrils than the outside of my nose. I think if I were willing to put Nizarol further up my nose than just the inside rim, I could eliminate the problem. But, at what cost? Lol. I don't want to ingest this stuff, lol. Either way, I am still happy! Head/Scalp: I have never had much of an issue with my scalp other than minor dandruff, for which I have always used Head & Shoulders. Despite this, I use this shampoo, as intended. I can not honestly tell if it is making any difference. Also, I have very short hair, so I cannot tell if this makes my hair coarse like everyone else says. If it does, I would use a conditioner like other reviews suggest. Ears/Earlobes: So, while it was more rare, but sometimes, my ear lobes and the bottom crease where the ear connected to my face would get dry and flake. I rub Nizarol on my ears, on the inside of my ears, and behind my ears/ear lobes. I have zero issues here now and never have to lotion this area any more. Forehead/Cheek Areas:These were not really problem areas unless it was cold/dry/windy. We have not had that type of weather, but I really do not think it will be a problem. Pelvic Area: I know this is a touchy subject, lol, but what I have to say is tame and could help some people. So several months back, something new happened, I noticed my pelvic area was dry as well, after using clippers. I used Nizarol in the creases of my leg, and in in my pelvic area, including directly on my -----. Results? Well, this has virtually eliminated the dry skin everywhere. Even better, I am chaffing less when running, which is awesome! I figured Nizarol was working everywhere else, so what the hell? Luckily for me, this was another minor issue it helped. Fingernail: Getting back to my fingernail, I had this white chalky/flaky formation under my fingernail. It had got to almost halfway down my thumbnail. It was causing my nail to lift. It did not hurt, but I thought it was unsightly. So I lifted the nail and put Nizarol in there. Again, possibly not safe, but a couple weeks in and my nail is almost back to normal. I eventually started cutting deeper into my nail to get the Nizarol farther back, which has worked. My nail almost looks normal and it looks like it is pushing the last of white to the font of my nail. So the growth stopped moving backward and it has improved. Another win! Others Uses?: As you can tell, I pretty much use this stuff all over. I put it on my elbows, the knuckles of my toes, and the point of my ankle bone. I think it is helping, but I am not 100% sure. What I can tell you is that it seems that it seems easier to get the dry skin off after applying the shampoo. A pedicure is on the docket and if I remember, I will update this review. Conclusion: Nizarol has worked way better than I could have hoped, and I did not even have to go to the dermatologist. I am hoping within a couple months, my skin will go back to normal. I am not sure if that will happen, but I love what Nizarol has done for me. I encourage anyone that has some of the issues I had to give it a try. Again, my issues were mild compared to some of the pictures I have seen, but I imagine if you are struggling with mild to intermediate issues, and you have not gone to a dermatologist, this could help you. I hope all this helps! Good luck! ****Update: 7/25/2017*** Fingernails: Nizoral completely fixed my nail problem! Face: So, when I first started using this product, I saw quite a bit of improvement. I no longer have red patches anywhere on my face. The only issue is that there have been diminishing returns. Nizarol has helped tremendously, but I still have dryness and dead skin issues. It is much more mild now, but still exists, however, I am grateful for the continued results. Scalp: Lol, I still cannot tell if this is helping or not. I still have minor dandruff. Nizarol has had no effect on my scalp as far as I can tell. Not a big deal for me though...
