Is this shampoo safe for daily use or for people with sensitive scalps?

ELFA PHARM Shampoo with Burdock Extract is designed for routine washing of hair that is prone to shedding or looks dull. The formula is mild, but individual reactions can vary. If you have a history of very sensitive scalp skin, start by applying a small amount and rinsing thoroughly to see how your skin responds. Avoid the product if you know you are allergic to any of its listed ingredients. In case of persistent irritation, itching or redness, discontinue use and consult a dermatologist. The shampoo does not contain harsh surfactants that are known to over‑dry the scalp, yet it is still advisable to monitor how your scalp feels after each wash. Using it two to three times per week is a common approach for people who want a gentle cleanse without over‑washing, especially when hair is already stressed by external factors.
