Neutrogena T/Gel Therapeutic Shampoo uses coal tar as its active ingredient to help relieve the scalp discomfort associated with dandruff, seborrhoeic dermatitis, and psoriasis of the scalp. Coal tar works by slowing the rate at which scalp skin cells multiply and by easing itching, scaling, and flaking. The range includes the original T/Gel Therapeutic Shampoo, T/Gel 2-in-1 Shampoo plus Conditioner, and the Extra Strength formulation for more persistent scalp concerns. Questions about T/Gel being discontinued relate to specific market withdrawals in some regions; availability can vary by retailer and period. Where a particular variant is temporarily out of stock, alternative coal tar or medicated scalp shampoos within the broader scalp care range may suit similar needs. Always read the patient information leaflet before use, and speak to a pharmacist if you are unsure which formulation is appropriate for your scalp condition. Ronaghan's Pharmacy stocks a selection of T/Gel products alongside a wider choice of medicated and specialist scalp shampoos. For additional options, browse the full Scalp & Hair Treatments range.
