Clark's 0.5% Coal Tar, 3% Salicylic Acid & 1.5% Sulfur Dandruff Shampoo, Full Spectrum, for Seborrheic Dermatitis, Psoriasis, Itching and Flaking Scalp, 8 Fl Oz

I always never leave a review. But this product is so effective that I am compelled to give a 5 star review. I tried close to every anti inch shampoo on the market, and also prescribed shampoo by a standby doctor who was not my usual dermatologist. Nothing worked. I finally got to see my dermatologist and explained to her what I had tried and she recommended this shampoo as well as prescribed topical cream. The cream was on back order so I only used this shampoo. After 1 application, I felt some relief. After 3 applications, all itchiness gone. I did not even apply the cream as a result. Yes, this shampoo smells but it's a small price to pay. I only applied it to the affected area, not the whole head so the odor was not too obvious. Now I only use it when I got a flare up. To me, this shampoo is godsend.

Good stuff. Most have either coal tar or salicylic acid. This has both.

I really like this shampoo but the smell and lather bother me somewhat. I find myself frequently having to shampoo twice in order to get clean hair. However, it does a good job keeping my scalp healthy and dandruff free. Plus it is very cheap- just remember to really shake the bottle before use

I've tried countless different dandruff shampoos over 30+ years. Some are moderately effective, but most are just lousy at controlling dandruff. Clark's Full Spectrum Dandruff Shampoo is the real deal; it not only controls dandruff flakes, it also reduces itching and scalp inflammation. This product is one of the few things I've purchased recently that actually exceeded expectations. While Clark's doesn't smell good, it doesn't smell bad. I've used coal tar dandruff shampoos for years that smell far worse and produce lesser results. Given how effective Clark's is, I can accept the fact it doesn't smell like mint, or cedar, or some other synthetically produced perfume.

I have used all of the most popular dandruff shampoos there is and never got any results. This is the first one that is effective and amazing! I’ve only used it for a few weeks now and I’ve seen significant improvement! My scalp is way less itchy and the redness is almost completely gone. By far the best shampoo for dandruff you can buy! In my experience it’s super effective and I will be continuing to use it. The smell isn’t the best but it’s not that bad!! Highly highly recommend!! I almost lost hope for my severe dandruff but this helped so much!!

Impossible to tell if it works, shower is intolerable as it's difficult to breathe through the smell, it's like standing in the exhaust fumes of a semi-truck. And I've used tar/sulfur/charcoal products before and I've never had an astmatic like reaction to it. Smell lingered in the bathroom for a day. Had high hopes. For anyone willing to try it, the shampoo separates so it has to be shaken before using. (I know this because despite the first encounter I tried it again thinking I could get over the stench, and it separated between uses.)

The smell (that people are often complaining about) wasn't actually as bad as I thought it would be. I saw someone describe it as a tire factory, and that's pretty accurate, but it's not overwhelming. The issue for me is that I'm allergic to the formula. The first wash left my scalp swollen and tender to the touch, and it took a few days to go away. I spot treated after that, and the area burned and was sensitive so I just put this product down for good. It might work, but I didn't really get the chance to find out because I'm allergic to it and it was causing more problems than it solved.

I am a 23 year hairdresser and had been looking for something that works for my daughter for years. She has very thick, beautiful wavy hair and needed something that would clarify and control oil without drying her scalp. She had a problem with flakes also. After trying more than a dozen professional brands, which by the way, are very expensive, I decided to give this a shot based on the reviews…. And to my delight, it worked and has continued to work ever since. Not to mention how affordable it is I have nothing but rave reviews about this product! At first, I did not subscribe. I just bought a few individual bottles, but about a month after she ran out the oil and flakes were back. So I recommend getting on the subscription so that it shows up without having to think about it. Great product, can’t say enough good things about it. And this is coming from a professional, who has used every line on the market. Big thanks to Clarks!!!!
