How often should I use this shampoo?

A shampoo with warming, scalp-stimulating ingredients is usually used two to three times a week, not every day. If your scalp gets oily quickly, you can use it more often; if you have a sensitive scalp, start with once a week and see how it feels. This is a cleansing shampoo, so massage it into the scalp and roots, not just the lengths. Rinse thoroughly. If the warming sensation feels too strong, rinse immediately and use a gentler shampoo next time.

For the lengths, you can follow with a small amount of conditioner or hair oil if they tend to feel dry. The hydrolysed wheat, oat and beer proteins in the formula are broken into small fragments so they coat the hair shaft more evenly, which can make hair feel smoother and look shinier without a heavy finish. That means you do not need to use a lot of product. If you use other scalp treatments, apply them at a different time of day so the shampoo can do its job first. If your scalp feels irritated or damaged, stop using this shampoo until it calms down.
