Yes. This product is described as a multi-use bath and body cleanser that also works as a hair wash, so you can use it from scalp to ends in the shower or sauna. The cleansing base removes sweat, excess oil, and impurities, while sorbitol helps hold moisture in the upper layers of the skin, which can make washing feel less drying. The plant oils (cedar, sea buckthorn, rosehip, burdock, flaxseed, walnut, and soybean) add emollient properties, so skin and hair may feel smoother after rinsing.
Because it is a soap-based cleanser rather than a typical shampoo, the feel on hair can be different. Soap-based washes tend to strip more of the natural oils and can leave hair feeling rougher or more 'squeaky' than a mild shampoo, especially on long or dry hair. If you use it on hair regularly, the product guidance notes that a conditioner or mask may be useful afterward, particularly for dry lengths. You can also use it as an occasional hair wash and keep your usual shampoo for daily use.
To use: wet hair thoroughly, work a small amount into a lather, massage the scalp and lengths, then rinse completely. If you have hard water, soap-based cleansers can leave a residue; rinsing well and following with conditioner usually helps. If your scalp is sensitive, patch test on a small area first, and avoid getting the lather in your eyes.
