How should I apply it on my scalp?

Apply the product directly to the scalp, not to the hair lengths. The product is designed for the skin under the hair, so focus on the scalp surface. Use your fingertips to massage it in — the massage step is the core of the product, as it helps distribute the solution evenly and produces the mild warming or tingling sensation that the product is known for.

You can use it before a wash or between washes, depending on your routine. There's no need to rinse it off immediately if you're comfortable with the product — it's meant to be left on the skin. Start with a small amount to see how your skin responds, especially if you're new to concentrated magnesium chloride.

Avoid the eyes and mucous membranes. If you're using it on freshly shaved, irritated, or very dry areas, be cautious — the product may sting slightly there. This is an external cosmetic product, not a medicine.
