How should I use this shampoo for best results, especially if I have a sensitive scalp?

Use the shampoo on wet hair: apply a suitable amount, massage gently into the scalp and through the lengths, then rinse thoroughly. The manufacturer notes that even a mild strengthening shampoo works best when paired with a suitable conditioner or mask for extra protection through the lengths, since the shampoo's primary role is cleansing while the conditioner addresses detangling and end-care. If your scalp is very sensitive or reactive, introduce the product gradually — for example, use it every other wash at first — and stop use if irritation appears. Avoid eye contact; if contact occurs, rinse immediately with plenty of water. Because the formula excludes silicones, you may notice less immediate slip during rinsing compared to silicone-based shampoos; this is normal and the follow-up conditioner restores manageability. Store at room temperature, keep the cap closed, and use within the period-after-opening indicated on the packaging.
