No, JELLY will not stain hair. It does not contain artificial colorants or dyes. It gets its faint pink color from minerals. We have not seen any staining in our in-house tests or extensive years-long salon testing in our Founder Jared's salon, nor heard any reports of staining from our thousands of JELLY hairstylists and at-home users.
Also, it only takes a small amount to have the desired effect. Put a pea-sized drop on your hands, and rub your hands together like you're applying lotion to your hands. Then run through damp hair, or dry hair, depending on the effect you're going for. You will literally feel like you're not putting any product in your hair, but it will show in the end result. The magic of JELLY is that it doesn't look like you have product in your hair, but rather like your hair just naturally did exactly what you dream it will do.
Hope this helps.
