How should tar shampoo be applied and rinsed off to get the best result?

Apply the shampoo to wet hair, concentrating most of the product at the roots — this is where oiliness builds up and where tar works most effectively. Gently massage the shampoo into the scalp with your fingertips for 1–2 minutes: this helps the active ingredients make better contact with the skin and remove impurities.

You can carefully spread the shampoo along the lengths, but without rubbing it in hard — the panthenol in the formula helps retain moisture, but there is no need to expose dry ends to concentrated tar. Rinse thoroughly: tar formulas need a good rinse so that they do not leave hair feeling heavy.

If your hair is very dirty or you have not washed it for a while, you can shampoo twice: the first application removes the main layer of dirt, the second cleanses more thoroughly. After rinsing, you can apply a conditioner or mask to the lengths if you like, avoiding the scalp — this helps keep a balance between clean roots and comfortable lengths.
