Polytar vs T/Gel: Which Shampoo Is Better for Dandruff?

Choosing between Polytar and T/Gel for dandruff? The most useful question is not simply which brand is better, but which formula suits your scalp. Polytar is a coal tar shampoo, while the T/Gel range includes different formulas that should not be treated as interchangeable.

The short answer: T/Gel Scalp Relief is an option to consider for dandruff with a dry, itchy, flaky scalp. Polytar is a coal tar treatment option for dandruff and certain other scaly scalp conditions. Neither is an automatic winner for everyone, and this guide does not establish that one works better than the other.

First, check which T/Gel you mean

T/Gel Scalp Relief contains salicylic acid and piroctone olamine. Neutrogena's current UK Scalp Relief formula lists 3% salicylic acid and 0.75% piroctone olamine. Salicylic acid helps break down visible flakes so they can be washed away, while the formula is designed to help reduce dandruff and its reappearance.

T/Gel Therapeutic is a different product: a medicated coal tar shampoo indicated for dandruff, seborrhoeic dermatitis of the scalp and scalp psoriasis. Its active ingredient is Neutar solubilised coal tar extract.

Other T/Gel products, including 2-in-1 and Dry Scalp versions, have their own formulations. Always read the exact bottle's ingredients and directions rather than assuming that every T/Gel shampoo contains coal tar or has the same strength.

What is Polytar shampoo?

Polytar Scalp Shampoo 150ml contains coal tar solution 4% w/w. It is a treatment option for dandruff and scalp conditions including psoriasis, eczema and seborrhoeic dermatitis, with associated itching, scaling and flaking.

This does not mean that every flaky scalp needs coal tar. If you do not know what is causing your symptoms, a pharmacist can help you choose a suitable treatment.

Polytar vs T/Gel Scalp Relief: the key difference

Polytar: a coal tar shampoo with uses covering dandruff and several other scaly scalp conditions. Consider it with advice from a pharmacist if you are looking for a coal tar treatment.

T/Gel Scalp Relief: a salicylic acid and piroctone olamine formula aimed at dandruff with a dry, itchy, flaky scalp. It is a different approach from coal tar, not simply a weaker or stronger version of Polytar.

Do not compare ingredient percentages as if they were a performance score. Different ingredients and coal tar preparations are not directly equivalent, and a higher number does not by itself mean better results.

What if you mean T/Gel Therapeutic?

Then the comparison is between two coal tar shampoos, rather than coal tar versus a salicylic acid and piroctone olamine formula. Both Polytar and T/Gel Therapeutic have uses that include dandruff, but their formulations and directions differ.

There is no basis in the product information used for this guide to declare either one universally more effective. Choose according to the exact product leaflet, suitability and pharmacist advice, not just the brand name.

How to choose a shampoo for your scalp

For dandruff with dryness, itching and visible flakes, T/Gel Scalp Relief is one option to consider. If you are considering coal tar, Polytar is another option, particularly where a pharmacist has recommended that type of treatment.

If you have thick scale, marked redness or persistent irritation, do not assume it is ordinary dandruff or simply buy the strongest-looking shampoo. A pharmacist or GP can help identify whether another scalp condition needs attention.

Prefer a combined cleansing and conditioning step? T/Gel 2-in-1 Shampoo & Conditioner 150ml is another formula in the range. Check its own label rather than using Scalp Relief or Therapeutic instructions.

Using anti-dandruff shampoo safely

Follow the instructions on your own bottle and leaflet, including frequency and any contact time. Do not transfer one shampoo's directions to another. Neutrogena's current Scalp Relief directions specify use two to three times a week; Polytar has separate directions.

Polytar must not be used by children under 12, on infected, open or damaged skin, or if you are allergic to coal tar or another ingredient. Coal tar can increase sensitivity to sunlight. Read the full warnings before use.

If you are pregnant or breastfeeding, buying for a child, using other scalp treatments or unsure about allergies, ask a pharmacist before choosing a product. Stop using a shampoo if it causes irritation and seek advice.

When should you seek help for dandruff?

The NHS advises seeing a GP if dandruff has not improved after at least four weeks of anti-dandruff shampoo, if your dandruff is bad or your scalp is very itchy, if your scalp is red or swollen, or if you have flaky, itchy patches on your face or elsewhere on your body.

The verdict: which is better?

Choose by formula, not by brand. T/Gel Scalp Relief is a dandruff-focused salicylic acid and piroctone olamine option. Polytar is a coal tar treatment option with uses covering dandruff and other scaly scalp conditions. If you mean T/Gel Therapeutic, you are comparing two different coal tar formulations.

The best choice is the one suitable for your scalp and circumstances, used according to its own instructions. If you are unsure, ask a pharmacist rather than relying on a brand-versus-brand verdict.
