We've Got Answers

How Often Should You Tone Blonde Hair?

Toning blonde hair depends on your color and how often it fades. For most, using a toner every 3–4 weeks is ideal. If you notice brassiness creeping in earlier, introduce a purple shampoo to your routine to maintain that fresh-from-the-salon glow. Your blonde, your rules—but consistency is key to keeping it just the way you love it.

How Do You Keep Blonde Hair Vibrant?

Keeping your blonde vibrant is all about the right routine. A great purple shampoo helps neutralize brassy tones while boosting brightness. Pair that with a deep conditioner once a week to lock in moisture and prevent dryness—because hydrated hair is happy hair. And don’t forget to protect your strands from the sun with products that offer UV protection—because a little love goes a long way in keeping your blonde locks looking their best.

Shocking this product sucks.

"I absolutely HATE this product. this product not only turned my hair orange but also as brittle as hair can be. the idea of this product is great! but unfortunately it does not turn natural blonde hair lighter which is its main purpose. I was so disappointed after using this product and I would not wish having orange hair on anyone i also think its such a waste of $16 and i would love it if refunding was an option. DO NOT BUY THIS PRODUCT."

Q&A

Hey! I’ve been using this hair lightener since 2023 and it’s given me beautiful results, and in December of 2025 I decided to dye my hair a light brown with semi permanent color, and as the months progressed, it’s faded drastically since then, and my hair is basically back to how it was before I dyed it. Do you think it would be safe to put some on my hair this summer?
Hey Lila, thanks so much for reaching out about this! Our Hair Lightener works best on very light brown to blonde hair. Since your hair color has changed a bit, I’d recommend trying it on an inconspicuous piece of hair first to see if you like the result. We also recommend that you use the product no more than 2-3 times a week in order to avoid hair breakage and damage. If you have any other questions, don't hesitate to reach out to us at hey@sunbum.com :) xo, SB
why is there no before and after photos using this product? i want to know what my hair will look like after using this
Hey Olive, thanks for reaching out! We don't have before-and-after pics since every hair color is a little different, so results can vary from person to person. Our Hair Lightener tends to work best on light brown to blonde hair, but everyone's hair has its own beachy journey! If you're curious about how it'll work for you, try it on a small, hidden section first and see what you think! We recommend using it no more than 2–3 times a week to help keep your hair happy and healthy. For those extra sunny, brass-free vibes, we also love pairing it with our Tone Enhancer or a purple shampoo :) xo, SB
Can I spray it in different parts of my body such as arm hair?
Hi there! Thanks so much for reaching out. With our Blonde Hair Lightener we would recommend avoiding direct contact with skin. What makes this product work is a lightening blend of ingredients including hydrogen peroxide, which oxidizes the melanin in the hair causing it to lighten. This product is intended to be used slowly and gradually and should be used on dry or damp hair directly to areas you want affected. If you have any other questions, feel free to reach out to us on our contact page. xo, SB

Is this hair lightener safe while breastfeeding?
Hi Lacy, Thanks for reaching out to us about this! Our recommendation would be to talk to your OB-Gyn and/or dermatologist to be sure that you’re getting the protection you need while still ensuring the safety of you and your baby.
