To help you choose the right product, we’ve put together this detailed FAQ and Buyer’s Guide, answering the most common questions about Neutrogena T/Gel and explaining which variant is best for your needs.

What does Neutrogena T/Gel do?

Neutrogena T/Gel is a dermatologist-recommended shampoo range designed to help control itching, flaking, and dandruff. Some variants are also used to relieve scalp conditions such as psoriasis and seborrhoeic dermatitis.

How does Neutrogena T/Gel work?

The active ingredient in most T/Gel shampoos is coal tar extract, which slows down the overproduction of skin cells on the scalp. This reduces flaking, itching, and irritation, while cleansing the hair and scalp.

Does Neutrogena T/Gel work?

Yes. T/Gel is clinically proven to control dandruff and scalp itching from the very first use. Many people notice improvement within a few washes, but results may vary depending on the severity of the scalp condition.

How long does Neutrogena T/Gel take to work?

Some people see results after just 1–2 washes. For persistent dandruff or psoriasis, it may take 2–4 weeks of regular use to see significant improvement.

How often should I use Neutrogena T/Gel shampoo?

Most people only need to use it 2–3 times per week. Daily use is usually not necessary unless recommended by a doctor.

Can I use Neutrogena T/Gel shampoo every day?

Occasional daily use is safe, but it may be too drying for some hair types. For maintenance, it’s best to use it a few times per week and alternate with a gentle, moisturising shampoo.

How to use Neutrogena T/Gel?

• Wet hair thoroughly.

• Apply shampoo to the scalp and massage in.

• Leave on for several minutes to allow the active ingredients to work.

• Rinse thoroughly.

• Repeat if needed.

Is Neutrogena T/Gel good for dandruff?

Yes. All T/Gel variants are formulated to tackle dandruff, with options for oily or dry scalps.

Is Neutrogena T/Gel good for psoriasis?

Yes. The T/Gel Therapeutic Shampoo is specifically recommended for scalp psoriasis, seborrhoeic dermatitis, and persistent dandruff.

Is Neutrogena T/Gel safe?

Yes, when used as directed. It has been widely used and dermatologically tested for decades.

Does Neutrogena T/Gel cause hair loss?

There’s no evidence that T/Gel causes hair loss. However, excessive scratching of the scalp from psoriasis or dandruff can sometimes lead to hair shedding.

Is Neutrogena T/Gel safe for colour-treated hair?

T/Gel is not specifically colour-protective. Some users report fading with frequent use, especially with freshly dyed hair. If you have colour-treated hair, limit T/Gel use to a few times per week and use a colour-safe conditioner alongside it.

Does Neutrogena T/Gel strip hair colour?

It may cause slight fading with regular use on dyed hair. Consider using it as a treatment shampoo rather than a daily wash.

Is Neutrogena T/Gel sulfate-free?

No, most T/Gel formulas contain sulfates to help remove oil, flakes, and buildup.

Does Neutrogena T/Gel smell?

Yes, the coal tar formula has a distinctive medicinal scent. It usually fades after rinsing and conditioning.

What conditioner can I use with Neutrogena T/Gel?

Any gentle, moisturising, or colour-safe conditioner can be used. Neutrogena also offers 2-in-1 versions that include conditioner.

What is the difference between Neutrogena T/Gel and T/Sal?

• T/Gel uses coal tar extract to slow skin cell turnover and reduce flakes.

• T/Sal (not currently stocked at Kennedy’s Pharmacy) uses salicylic acid to break down scalp build-up.

Is Neutrogena T/Gel tested on animals?

Neutrogena is owned by Johnson & Johnson, which has policies against animal testing unless required by law in certain countries.
