What is the difference between this product and the tarsum shampoo/gel from summers 8 oz.?

Thank you for your question. There is no difference - this is a recent packaging change. Tarsum Professional Shampoo/Gel is now Tarsum Relief Shampoo. We apologize for any confusion!

I color my hair a reddish brown. Will it strip the color out? Especially the red tone?

I've been coloring my hair a deep auburn red for years and have been using the Tarsum shampoo for almost 2 years and as of yet it has not changed or stripped the color at all. Remember though that red color usually fades quicker than other colors. I normally color my hair every 5-6 weeks.

How long can I leave this in my hair before washing it out?

Directions: For use as a scalp treatment before bathing: twist open applicator tip. Apply evenly on affected areas. Leave on for 5 minutes, gradually increasing treatment times to 1 hour, or as directed by a doctor. Then rinse thoroughly with water. As a shampoo: wet hair, apply Tarsum, up to 10 minutes, then rinse. Use daily until flaking and itching are under control, then at least twice a week or as directed by a physician.

Thank your for your question. Tarsum Relief Shampoo is manufactured in the United States.

I find this product to be super effective, and I can actually feel the shampoo dissolving scalp buildup immediately upon application. It’s most effective when applied to a dry scalp and left to sit for a few minutes, making sure to thoroughly work it in and massage the area. I don’t mind the mentholated scent at all because the results let me know the product is truly working.

It's very expensive for it's size i also have to pay for postage it coming from a non eu country but it does work with my psoriasis in hair. Unfortunately it does not work on my psoriasis elsewhere buy to be fair nothing does Well I ordered another bottle so I'd say I'm happy

Recommended by my dermatologist. I swear you only need to do it a couple of times. The first time for 15 minutes. The second time leave it on for an hour. It is a very foaming shampoo. I use a good moisturizing cream rinse after. It works for flaking and itching and lifting of the scalp!
