Can I use this henna cream on already colored or bleached hair?

Fitocosmetic Strengthening Henna Cream Blond is designed as a gentler alternative to traditional permanent dyes, but when applied to already colored or bleached hair, additional considerations apply. Hair that has been lightened or previously treated with chemical dyes is typically more porous and fragile, which can affect how the henna-based agents interact with the strands. The cream's conditioning ingredients, including burdock oil, may help soften and add manageability to dry or damaged lengths, but they do not repair structural damage caused by prior chemical processes.

Before full application, it is advisable to perform a strand test on a small, hidden section of hair. Apply the cream as directed and leave it on for the recommended time, then rinse and observe the colour change and hair feel. This test helps predict how your specific hair type and current condition will respond. If the hair is very light, highly damaged, or has undergone multiple chemical treatments, consider consulting a hair professional to ensure compatibility and avoid potential adverse reactions such as excessive dryness or uneven colour deposition.

Additionally, users with sensitive scalps should patch test behind the ear or on the inner arm 24–48 hours before use to check for any allergic response. If irritation occurs, discontinue use and seek professional advice.
