How should I use Modum KLASSIKA brewer's yeast shampoo for the best results? — MODUM KLASSIKA Beer Yeast Shampoo, 550 ml

Use it like any liquid shampoo: wet the hair thoroughly, apply enough to cover the scalp, massage gently with the fingertips and let the lather travel through the lengths. Rinse well so no product remains on the hair or scalp.

If your hair is limp at the roots and dry at the ends, concentrate the shampoo on the scalp and let the foam rinse over the ends rather than scrubbing the ends directly. That keeps the root area feeling cleaner and more voluminous while limiting unnecessary friction on the driest parts. Then follow with a conditioner or mask on the lengths, especially for brittle or tangle-prone hair.

The product is intended for a simple routine: use it when you want cleansing with a more strengthening, volumising feel than a basic shampoo. Because it is rinse-off, there is no leave-in step. Avoid contact with the eyes, and if irritation appears, stop using it. If you wash your hair unusually often, you can still keep it as your regular shampoo and adjust the conditioner to the season or styling routine.
