Protects
I buy this regularly. Naples products are expensive, but they last a long time, because you only need a small amount. So when there are Olaplex offers, I take the opportunity to stock up. I find this Intensive Bond Builder protects my hair from water damage before I shampoo, and gives it a lovely shine.

There's a knack
After a couple of attempts I've figured out the best way to apply this for me. I wash my hair first with the olaplex cleansing shampoo, then spray this, section by section on my hair once it's only slightly damp, this allows the product to spread more easily. When spraying hold a hand behind to catch any spray so that you can apply it rather than waste it.

Use with No3
It's a lovely product to use with No3 treatment. The spray bottle is rather rubbish at dispersing the product, and product arrived leaked.

Love the spray bottle!
Use this to go hand in hand with Olaplex no3. This is my 3rd bottle as I think no3 works best with this. Love the new spray bottle version so much more convenient! Best value on LF too so will always purchase from here :)

Terrible spray bottle
A lot of product is wasted when applying as the spray blasts at your scalp or neck rather than spraying as a mist. I wouldn’t buy agsin until the nozzle is improved

Invaluable
Use alongside number 3 for the best pre wash treatment. The spray bottle works much better than the bottle with the long nozzle but it could still work better to avoid waste, I would deduct half a star if I could but if Olaplex could just make the spray nozzle a little better then it would be perfect!
