How to use MONAT BOND IQ
6 min read Care know-how Updated 2 September 2026
If your hair is brittle, snaps quickly or has been over-processed by colouring, bleaching and heat, Bond IQ™ is made for exactly those lengths. It is a leave-in that stays in the hair after washing and strengthens the fibre day to day, so the lengths look more supple, more combable and more resilient. To get its best, timing, the right amount and a little patience all matter. One thing up front: Bond IQ™ cares for and protects, it doesn't structurally rebuild damaged hair. The gain sits in the feel, the look, and less avoidable breakage while you style.
What this means at MONAT
The MONAT method works to the principle of Prep, Styling, Finishing. Bond IQ™ is the Prep layer, the first thing that goes into the lengths after washing and the base for everything that follows. First this nourishing leave-in layer, then the heat protectant, then styling and finally the finish on dry hair. Keep to that order and you get more out of every single product.
Where Bond IQ™ fits in your routine
Bond IQ™ is a leave-in and belongs at the start of the care that stays in the hair, not in the cleansing step. The order is simple: shampoo first, rinse out conditioner if you use it, and then Bond IQ™ goes into towel-damp, squeezed-out hair. Damp, not dripping, because if the hair is too wet the product dilutes and spreads less evenly.
Bond IQ™ has its place before styling and before the heat protectant. It is the base layer on the lengths that blow-drying, straightening and air-drying build on.
How much, and where exactly
Start with a small amount. Less is almost always more here, because too much product weighs down fine hair especially and can look stringy. Work Bond IQ™ mainly through the mid-lengths and ends, where the hair is oldest and most stressed.
Leave out the roots and scalp. The root is fresh and doesn't need this extra care, and applied close to the scalp it can make the hair look flat and greasy sooner. Work the leave-in in with your hands, then comb it gently through the lengths with a wide-tooth comb, so it reaches every strand evenly and helps with detangling at the same time.
Your wash-day sequence
- Cleanse with shampoo as usual and rinse well.
- Use conditioner if you need it and rinse thoroughly.
- Squeeze gently with a towel until the hair is damp rather than wet.
- Work a small amount of Bond IQ™ into the mid-lengths and ends, skipping the roots.
- Distribute it evenly through the lengths with a wide-tooth comb.
- Apply heat protectant and style as usual.
With heat protection and styling
Bond IQ™ doesn't replace a heat protectant, the two work hand in hand. First the nourishing leave-in layer, then the heat protectant, then the tool. On over-processed hair this combination is the crucial point: well-supplied, protected lengths break less often when you blow-dry, brush or straighten. The heat protectant adds to the leave-in, it doesn't replace it.
When styling, still use the lowest sensible temperature and as few passes as possible. Bond IQ™ makes the hair more supple and easier to comb, which lowers the mechanical pull during detangling, but it doesn't make heat harmless.
How often, and what you can realistically expect
On clearly stressed hair, Bond IQ™ can be used at every wash. As the hair settles, you can scale it back to as needed, for instance when you notice the ends turning rough or unruly again.
Expect a feel-and-care benefit, not a repair. The hair feels stronger and better cared for, is easier to manage and breaks less while you style. That is a win for look and handling, not structural healing. Whether Bond IQ™ as an ongoing routine or the spot finish Rejuvabeads suits you better is something we work out in the guide Bond IQ or Rejuvabeads. And once split ends travel up the length, in the end only a haircut helps, no leave-in removes split ends.

Quick questions
On wet or towel-damp hair?
Towel-damp. Squeeze gently so the hair is damp but not dripping, that is when the leave-in spreads best.
Can I use Bond IQ every day?
It is made for every wash. On very stressed hair use it regularly, otherwise simply as needed, because too much product weighs the lengths down.
Does Bond IQ replace my heat protectant?
No. Apply Bond IQ™ first, then the heat protectant, then style. The two complement each other.
Does it repair damaged hair?
No. It strengthens and protects, so the lengths look stronger and break less, but it doesn't heal the fibre.
