Product Description

The only psoriasis shampoo designed to be applied full strength, directly to affected areas BEFORE bathing! When ready, simply add water, lather and immediately rinse. No more waiting in the shower with a headful of smelly lather!

Tarsum is the only therapeutic shampoo designed to be applied BEFORE bathing. Its special applicator tip allows you to put Tarsum directly on psoriasis plaques. You treat your scalp, not your hair!

Why is this better?

Every other therapeutic shampoo requires you to dilute the medication and stand around the shower with a headful of lather to receive treatment.

Applying Tarsum

    Tarsum directly to the scalp before bathing allows you:

  1. full strength, undiluted treatment exactly where you need it most
  2. better control over the amount of time you treat your scalp.

Tarsum maximizes treatment time and minimizes shower time

Use Tarsum’s applicator tip to apply Tarsum directly to the affected areas of the scalp. Leave Tarsum on for a short period (while you brush your teeth, shave, eat breakfast, watch TV etc.) for up to an hour before bathing.

When you are ready to remove Tarsum, simply add water, work Tarsum into a lather, and rinse as you would any shampoo. Tarsum produces a thick lather with water. You may need to add a little more Tarsum if you pretreated only a small area on your scalp.

SPECIAL TIP: Tarsum was designed for scalp use, but many dermatologists have patients apply it to other parts of the body (except the genital area, unless directed by your dermatologist) to reduce the scaling of psoriasis plaques. Tarsum used on other parts of the body should not be left on longer than an hour. Discontinue use if Tarsum causes irritation.

Rated 5 out of 5 by from Summers Labs Psoriasis Products I have suffered with Psoriasis for more than 40 years and received a couple of sample bottles of Tarsum shampoo sometime in the 1980s and this product changed my life and the extreme extent that I had Psoriasis in my Scalp. If Summers Labs Still had 1oz bottles available I would still be giving this product to other suffers, it has not only changed my life but 100s of other Individual's that I continue to give this product to. Thank you Summers Labs for your comment to helping those who suffer from Psoriasis. I have just recently started using cutar emulsion and this product is the some as above product amazing.

Rated 5 out of 5 by from it works! My dermatologist recommended tarsum for my scalp issues. I have very long hair however I suffer from dandruff and itchy scalp. This product had turned my world around. My stylist also recommends tarsum to other clients.

Rated 5 out of 5 by from I've tried them all, this one keeps working My psoraiasis is mostly on my head. I've been dealing with flakes my whole life. I've used lots of different shampoos, and they usually work for about a month, but eventually the flakes flare up again. Not with Tarsum. I've used it since the late '90's and as long as I use it regularly (everyday), I never have to worry about dandruffy flakes on my shoulders. No unpleasant oders either. Not only does it work, but it just good shampoo, too. I wash with it by itself and don't use anything else, not even conditioner, and my hair's good.

Rated 4 out of 5 by from Best stuff for my itchy scalp A dermatologist recommended Tarsum to me about 10 years ago. It's the best treatment I've found for my chronically itchy scalp. It's also a fairly gentle shampoo -- other OTC dandruff shampoos that I've tried have been very drying, which increased my itchies. I'd give it 5 stars except for the fact that the price has gone up so much!

Rated 5 out of 5 by from It may smells like surfer, but it works! I have been using this product for over 10 years. I use it once a week to keep the flakes in check. Over the years, I tried many products, many of them worked for a while, then stopped working. When I get back to Tarsum again, I have to use it twice a week for about 2 weeks to get the flakes down, then back to once a week. Why would I try other products if Tarsum works? Well, I have to buy Tarsum online, and the gel color is scary, not to mention the smell (gotten better lately). As to how do I know it works well? One, my head doesn't itch. Two, my eye glass is not covered in skin flakes 30 minutes after I cleared it. When I use Tarsum, I use a clarify shampoo first to get rid of the conditioner, spray and what not that's on my hair first. Then I follow the instructions and shampoo twice with Tarsum. After wash all Tarsum off my hair, I then put my regular conditioner on.

Rated 5 out of 5 by from Best Tar Shampoo I have used this shampoo for over 30 years to control my psoriasis, I tried many others long ago and even recently when my dermatologist gave me free samples. Because I have long hair I appreciate that this shampoo is thinner/more fluid and in a bottle with a pointy cap that I just tip over and rub straight into my scalp. This makes it simple to distribute the shampoo all over my scalp without having heavy glops of it on the ends, never getting where I need it most. A few times when I ran out I used other non-tar products and within a few weeks I had heavy flare-ups. This is by far the best solution to control my itching and flaking from psoriasis. One drawback is the tar scent, which is not horrible. But it is not what anyone would call a desirable scent. But after using a conditioner and after my hair dries, no one can even smell it. I also wish I could get this in the gallon size bottles like I used to many years ago. Buying in bulk is a bit cheaper and saves on the waste of so many plastic bottles.

Rated 3 out of 5 by from Not Much Difference This is my second bottle of Tarsum and I really can't say that I see a huge difference. I still have the same problem, but just not as severe as it can be. I do think I will continue to use it to give it a little more time.
