I have fine, thin hair with itchy patches on my scalp. Last year, My doctor had prescribed ketoconazole 2% shampoo, which worked great. Then I discovered I can buy Nizoral in a 1% solution. This works great too! I also like how it leaves my hair: silky soft and shiney, but not limp or greasy! I use it a lot now, even when my scalp is not itching. It has a light, clean fragrance.

Of all the products I've tried over the years, Nizoral works best at clearing up my itchy,flaky scalp. My doctor recommended it over Rx products and she knew what she was talking about. I only use it once a week and that is usually enough, but during high stress times, I use it every other day until my scalp clears up.

If the usual dandruff shampoo suspects haven't helped your symptoms, this is for you. It's blue and smells like Head & Shoulders, only its active ingredient is a non-prescription strength of the anti-fungal Ketaconozole and works like a charm. My first time using it dried up my scalp itch and alleviated all the redness and tender spots. It is very drying and I only used it every 3 or 4 days, letting it sit while in the shower but always followed it up with a conditioner. About twice a month keeps my scalp clear after the initial 8 weeks (per the label). So if you are prone to any kind of yeast infections, from antibiotics, birth control, Prednisone or diet, this stuff works.

DON'T USE IT EVERY DAY! Read the label - use it once every 3-4 days, which would be about twice a week. I have long, thick hair, and the small bottle lasts months. A little goes a LONG way; lathers very well. With any shampoo, you should only lather once unless your hair is truly filthy. Leaves my curly hair feeling clean and healthy, not stripped. It smells nice and clean, not medicinal. I follow with a leave-in conditioner, yet it doesn't get dirty any more quickly than with other shampoos - can go 2-3 days in a pinch. Just don't understand those who talk about it making their hair get dirty quicker. I use this 2 days a week and often alternate with a different type dandruff shampoo in between. This "cocktail" controls my severe dermatitis (heavy scaling, itchy, weepy crusting, etc.) better than anything else over the counter or prescription. If this has no affect on your dandruff, yours is probably not caused or affected by yeast. If it is, as is often the case, this should help.

My husband has non-specific and occasional occurrences of dermatitis on his scalp. Nizoral works very well, and then starts to loose effectiveness. He needs to switch to another brand of formula for awhile and then go back to Nizoral.

I had Tinea Capitis (also called ringworm of the scalp) -- lots of dandruff, itchy scalp, red spots on my scalp and reduced hair growth. I used Nizoral and literally 3 days later it was all gone. I use now twice a week to maintain.

I read recently that Nizoral was also good for those that have a overly oily scalp. I've used it for 3 weeks now and I find it to be amazing. It's the only shampoo that makes my hair feel like it's clean. I could not be happier!

I purchased this immediately after it became available and in 1 week I was able to tell a difference. It completely cleared up all dandruff and kept it away for weeks. I've used this shampoo for years about twice per week. However, because of the price I didn't always have it in stock. Whenever I had a relapse I would get it again and it would clear up my head by the 2nd use. Lately though I've noticed that it doesn't work as well as it used to. My dandruff has returned and I'm not sure if it's because I've built a tolerance to the shampoo, my condition has worsened, or if the shampoo has changed. I've always had very long thick hair and I noticed that long term use of this product has had a noticeable lessening/thinning of my hair. Overall, I would suggest to anyone to try this product. It has a gentler odor that other medicated treatments; it works fast, and left my hair soft and manageable. Just be sure to cut back on the frequency of use once the condition is under control.

This product works great for me -- and as long as I don't use it too often, it doesn't make my hair too dry or too oily. I used it every other day at first, and now I use it once or twice a week. What I love about this shampoo is that it doesn't smell bad, like other dandruff shampoos I've tried.

I have seborrheaic dermatitis and I've tried almost every product on the market. Nizoral should only be used once or twice a week, otherwise, it will have adverse affects. When I first purchased the product, I used it every day for two weeks. I ended up with an extremely dry scalp and experienced hair loss. Now, I use Nizoral once a week and Herbal Essences anti-dandruff shampoo daily, followed by a light conditioner. It's the best combination.
