Rihanna is known for many things, including her Caribbean-infused pop music, her edgy fashions and her ever-changing hair color. The beauty from Barbados has sported dark locks and blonde strands, and most recently made waves as a redhead.

However, women who change their hair color as often as Rihanna should take a few precautions to ensure that all the dyes don’t harm their locks.

“Before making a major color change, I always dye a tiny, underneath piece of hair,” Ursula Stephen, Rihanna’s hairstylist, told Allure. “This way, you can see the outcome of the color before committing. You want to be sure you’ll like the new color, since dying your hair too close together can damage it.”

Heat and UV rays can damage color-treated hair, so Stephen suggests avoiding high-heat hair treatments in favor of gentler methods, and misting strands with a UV-protecting spray, such as L’Occitane Summer Protection Sun Hair Mist.

Finally, Stephen recommends using a moisturizing cream daily, and concentrating the product on the ends, as they are usually the most damaged portion of the hair shaft. Hamadi Shea Hair Cream can be applied to wet hair or at night for extra conditioning while you sleep.
