Marketing - what story do you want to tell
Technology - You’ll want to include silicones to detangle hair, make it more shiny, and make it feel better. Humectants can help too.
Nothing will actually repair the hair. All you can do is to create a thin coating on the hair that makes combing, shine, feel, and manageability better.

Thanks Perry for reply.
I mean, while selecting ingredients for conditioner what I should keep in mind in terms of it’s ionic nature, pH, etc. since it is leave on product.
What could be the basic difference between rinse-off and leave on conditioner?
Are the emulsifiers, active conditioning agents, their concentrations, ionic nature, pH range different for rinse-off and leave on conditioners?

What I should avoid in leave-on conditioners?

@bsingle for what I’ve seen, leave on conditioners are the same as rinse off, just made much lighter with significantly lower concentration of conditioning agents.

Yes, lower levels of conditioning ingredients are needed in leave-on versus rinse-off. It’s up to you to experiment but say you use 1% Dimethicone in a rinse-off, you could probably get the same effect using 0.1% in a leave-on.
Leave-on conditioners also allow you to use water soluble ingredients that just get rinsed down the drain in a rinse-off product. So you can use Glycerin or Propylene Glycol for a humectant effect. Or you could use Dimethicone Copolyol which is water soluble.
The other main difference is the use and level of cationic surfactants. They are the main conditioner in rinse-offs. Unfortunately, they can be irritating when left on the skin too long. Cetrimonium Chloride actually has a safety limit of 0.25% in a leave-on product. But for leave-on you don’t need cationic surfactants.
pH should be around 4.5 - 5.0. Rinse off conditioners have a lower pH because you want the cationic surfactant to stick better. But with leave-on, this is less of an issue.
