T Gel vs T Sal: Which Shampoo To Pick?

By: | Last Updated: April 30, 2023

Are you suffering from a dry, itchy, and flaky scalp? If yes, then you might have seborrheic dermatitis! 

Seborrheic dermatitis is a skin condition that causes itchiness and flaky scales on the skin. It causes redness on fair skin and pale spots on darker skin and usually occurs on the scalp. 

It is also known as seborrheic eczema, seborrheic psoriasis, or simply dandruff. 

The most common remedy for this dilemma is using an anti-dandruff shampoo. However, most of these products contain harsh ingredients that may harm the hair and scalp. Thankfully, Neutrogena is here to the rescue! 

Over the years, Neutrogena has produced shampoos that deliver quality results. Two of which are the T Sal and T Gel products. 

Both provide relief for different scalp conditions, including seborrheic dermatitis. And the good news is that these medicated shampoos don’t need a doctor’s prescription!

So what exactly do these shampoos do? And is T Sal the same as T Gel? Read along to find out!

What is the difference between T Sal and T Gel Shampoos?

Both T Gel and T Sal help treat dandruff. However, they differ in a few ways.

1. Ingredients 

Neutrogena T Gel shampoo has coal tar which deeply cleanses the scalp. And not just that! It also has soothing chemicals that remain on your inflamed scalp even after rinsing. 

On the other hand, Neutrogena T Sal shampoo contains salicylic acid. This ingredient treats hair loss, which is a result of severe seborrheic psoriasis. 

2. Appearance and Smell

Another major difference is their appearance. 

The T Gel shampoo is deep brown because of its coal tar ingredient, while T Sal has a clear color. T Gel also has a powerful aroma and smells like tar. Many T Gel users recommend washing with a fragrant conditioner after to cover up the scent of this shampoo. 

On the other hand, T Sal has a light antiseptic or rubbing alcohol scent. Nevertheless, both shampoos smell like medication.

T Sal is a more powerful deep cleansing solution that eliminates residue. 

It goes beyond treating more severe scalp conditions that result in skin cell build-up. The salicylic acid in T Sal breaks down these skin cells, thereby removing flakes. 

Simply put, T Sal treats seasonal flare-ups of seborrheic dermatitis. It treats scalp rashes, acne, and flakes of skin behind the ears and neck. 

How often can you use T Sal shampoo?

According to their official website, you should only use T Sal shampoo twice a week or as your doctor advises.

T Gel has coal tar that treats psoriasis, dandruff, and seborrheic dermatitis. This ingredient has an anti-inflammatory effect that helps alleviate itch and eliminate psoriasis-related flakes. It also slows down skin cell growth.

Can you use Neutrogena T/Gel every day?


You should use Neutrogena T Gel twice a week max. However, the duration may vary depending on your doctor’s instruction. 

Use this shampoo only just as instructed. Use it sparingly and no longer than recommended. Otherwise, you may experience scalp irritation or hair follicle problems. 

Also, don’t use this shampoo if you’re allergic to coal tar or have rashes or open blisters on your scalp. 

Can you use too much T/Gel?

As mentioned earlier, using too much T Gel may cause serious side effects like scalp irritation or hair follicle problems. In rare cases, you may also experience allergic reactions, such as rash, dizziness, or difficulty breathing. 

How to use Neutrogena T Sal and T Gel Shampoo

It’s simple! 

Begin by thoroughly wetting your hair with lukewarm water. Next, apply the shampoo liberally on the scalp. Massage into your head and leave it for a few minutes. Rinse with warm water afterward.

Can I use both products altogether? 

Yes! But consult your doctor first. Some may advise taking both at once if your scalp is severely affected.

In that case, soften the tough flakes first with T Sal and apply T Gel right after for a spotlessly clean scalp. 

Customer reviews: Yay or nay? 

Absolutely yay! Both T Gel and T Sal shampoos both got positive ratings from their users.

Most T Gel consumers claimed that the product effectively treated their dermatitis, dandruff, or psoriasis. The only downside was its strong odor. 

For T Sal, most of its users were also satisfied, saying that their scalp’s health improved after using the shampoo. Their hair became shinier and more robust too! 

The verdict: T Gel or T Sal? 

Indeed, these two medicated shampoos do wonders. But which of the two should you use? 

Well, if you’re suffering from less severe scalp conditions, then T-Gel is the best choice. This shampoo helps alleviate scalp irritation and other mild psoriasis or dandruff symptoms since it slows down skin cell growth.  It’s the best choice for those who want long-lasting itch and flake relief. 

However, if your condition is extreme, T Sal is suited for you. T Sal manages severe symptoms, like excessive flaking. Salicylic acid, its potent active ingredient, strips away build-up. 

Final thoughts 

So there you have it! T Gel and T Sal shampoo differ in several ways, so you must know their respective ingredients and uses. 

It’s also equally important to take precautions before trying out these two shampoos. 

So tell your doctor about any allergies or illnesses you may have, any drugs you are taking, whether you are pregnant or nursing, or any other relevant health information. These factors may affect your medication. 

Doing a patch test first is also highly recommended. 

When using it, avoid eye contact and excessive sun exposure. Treated areas like your scalp and neck may be more sensitive to the sun. So you should use a cap as protection. 

Look out for color staining too! T Gel shampoo may stain your color-treated hair and your clothing. So be careful! 

Remember that T Gel and T Sal are not ordinary shampoos — they are medicated shampoos. So if you notice any adverse reaction, stop usage immediately and consult your dermatologist.
