As the name implies, coal tar shampoo is a medicated product that contains coal tar as an active ingredient. It works by decreasing skin cell turnover, a key feature in psoriasis. This product also helps get rid of excess dead skin cells that are currently on your scalp.

There are multiple over-the-counter (OTC) formulas, each with varying amounts of coal tar and other ingredients.

Coal tar is primarily used in the treatment of psoriasis, seborrheic dermatitis, and other conditions of the scalp. It’s designed to target excess dead skin cell turnover and buildup right at the source.

By targeting excess dead skin cells, you may also find relief from itchiness, red plaques, and other symptoms. Additionally, getting rid of psoriasis patches on the scalp may help your prescription topical treatments work better by allowing more absorption.

Our roundup of the 12 best coal tar shampoos for psoriasis is based on the following factors:

  • customer ratings
  • user reviews
  • active ingredients
  • scent and added fragrances
  • moisturizers

Coal tar shampoo may be used up to twice a week or as directed by your doctor. Some products claim they’re safe for daily use, but you may consider doing so only temporarily. It’s not clear whether coal tar shampoo is safe for daily, long-term use.

Talk with your doctor before trying any new product for your scalp. This includes OTC coal tar shampoos. Also, it’s important to keep in mind that coal tar shampoo should be used as a complement to other psoriasis treatments your dermatologist recommends.

If your doctor gives you the go-ahead to try any of the above 12 coal tar shampoos, be sure to monitor your symptoms and call them if your scalp condition worsens. Key signs to look out for include increased redness, burning, or irritation.

Finally, know that if coal tar isn’t a good fit for you, there are other types of medicated shampoos that may help. Talk with your doctor about other options, such as shampoos with salicylic acid.

How often should you use coal tar shampoo?

This largely depends on the severity of your condition, as well as the product type. Some products are designed for use twice per week, while others may be used every day. Check all product directions carefully, and ask your doctor for advice.

Does coal tar shampoo cause any side effects?

In some cases, coal tar shampoo can aggravate an already sensitive scalp. Side effects include irritation, burning, redness, and itchiness. If you experience such effects, stop using the product and call your doctor.

Coal tar shampoo can also increase your scalp’s sensitivity to the sun, increasing your risk of burns. Be sure to wear hats when outdoors while you’re using this type of shampoo. You may also consider applying scalp sunscreen if needed.

Will coal tar shampoo bleach my hair?

Coal tar shampoo isn’t recommended for color-treated hair, as well as naturally gray or blonde hair colors. This is because coal tar may discolor light-colored hair.

Can using coal tar shampoo lead to hair loss?

It’s not clear whether long-term, daily use of coal tar shampoo leads to hair loss. However, hair loss itself may be seen in scalp psoriasis due to dry hair and from scratching your scalp.

What type of conditioner should I use?

While coal tar shampoo can help keep your scalp healthy, you’ll still need to follow up with a conditioner to keep your hair healthy, too. Ideally, you should opt for a moisturizing conditioner to counteract the drying effects of coal tar.

How do you get rid of the coal tar shampoo smell?

Some brands contain added fragrances to help mask the strong smell of coal tar. However, coal tar has a strong scent that may still linger despite fragrances. Moreover, sensitive skin may react negatively to perfumes added to shampoo.

You may not be able to get rid of the coal tar smell entirely, but you can help reduce it by using leave-in detangling and conditioning sprays on towel-dried hair.
