how to use

After you shampoo SKIP THE CONDITIONER OR HAIR MASK. Apply to damp, towel dried hair. Work through the mid-lengths and ends and do not rinse out. Leave in for at least 4 minutes, then style as usual. Use after every wash, weekly, or monthly depending on your level of hair damage. Why 4 minutes? It takes 4 minutes to repair damage at the molecular level by targeting the cortex of the hair.​

Depending on your hair length and thickness, use 1-4 pumps to coat your hair from mid-lengths to ends. For best results, use after the Rapid Repair Bond Builder+ Shampoo and follow with Bond Builder+ Finishing Oil.

Why skip the conditioner? Conditioner works to seal the hair cuticle, and this new format of hair technology needs to be able to penetrate the strands to the cortex to repair.

Q&A

Hello! Could I wash my hair, put this mask on and leave for four minutes, then use conditioner and rinse? Would I receive the full benefit applying it this way?
Hi Teri, Thanks for your question! For the best results, shampoo your hair, skip the conditioner, and towel dry your hair. Then, apply the Leave-In Conditioner and let it sit for 4 minutes before styling as usual. This will give you the full benefit of the product!
I only wash my hair with shampoo and conditioner twice a week. Can you use this on days when I just wash my hair with water?
Hi Angie, Great question! The Rapid Repair Bond Builder+ Leave-In Mask is designed to be used as a weekly treatment for that extra boost of nourishment and hydration. It's best to apply on your shampoo and conditioner days for maximum benefit, and to avoid over treating.
How often can I use the new bond builder range? Is it safe to use weekly?
Hi Abbie, Thanks so much for reaching out to us. We appreciate your interest in our newly revamped Bond Builder Rapid Repair range. The good news is, our new Rapid Repair has also been updated to a more lightweight formula so all hair types can now experience stronger, shiner, healthier locks. Meaning this range can be used in place of your regular Shampoo and Conditioner, even for finer hair types. You can use our shampoos as often as you like. We recommend washing your hair every other day or every 2 -3 days depending on your. However, if your hair is visibly oily, your scalp is itching, or there's flaking due to dirt, those are signs it's time to wash your hair. If you have any further questions, feel free to get in touch with us at wecare@bondiboost.com.au - Larissa from the CS team.
My hair is very tangled and knotted after shampooing, especially not using conditioner, so it is very hard to apply this leave in mask evenly. Any suggestions?
Hi Alyssa, Thanks for getting in touch with us. Oh sorry to hear, I would recommend going through smaller sections of your hair with a wide-tooth comb before applying the Bond Builder Leave-In Hair Mask. Starting from the ends and work your way up to avoid breakage. If you have any further questions, feels free to get in touch with the CS team at wecare@bondiboost.com.au
Is this safe to use during pregnancy?
Hi Mel, Thanks for the question! Our haircare products contain naturally derived (many certified Organic) ingredients with a very gentle preservative. While we believe our products are safe to use, I recommend providing the ingredients to your medical professional to give the all-clear first. Feel free to get in touch with us if you have any further questions. - Larissa from the CS team
