How should I use this shampoo for the best cleansing and volumizing effect?

Start by wetting hair thoroughly with lukewarm water; hot water can strip the scalp of natural oils and may reduce the refreshing feel of the Dead Sea minerals. Apply a small amount of shampoo to the palms, rub together to create a light lather, then distribute evenly from roots to ends, focusing on the scalp where product buildup and dust tend to accumulate. Massage gently with fingertips for 20‑30 seconds to allow the chitosan film to form and the seaweed extract to contact the scalp; avoid vigorous scrubbing that could irritate sensitive skin. Rinse completely until no suds remain, as residual product can weigh hair down and counteract the light‑root effect. If you use styling products such as gels, sprays or dry shampoo, a second lather may be needed to ensure thorough cleansing, but limit washing to two times per week unless your scalp feels unusually oily or you have been exposed to heavy pollution. After rinsing, follow with a lightweight conditioner or a hydrating mask on the mid‑lengths and ends, especially if your hair is porous, bleached or naturally dry, to replenish moisture that the mineral‑rich wash may have lifted. Finish with a cool‑water rinse to help close the cuticle and enhance the smoothing effect of the pearl proteins, which can improve light reflection and give a smoother, more manageable feel.
