GarnierFructis Style Pure Clean Styling Gel 6.8 oz

I need a product that separates each hair and holds it with thickness rather than stickiness. Will it be suitable or which one would you recommend?

Can I use this on my dog’s Mohawk ?

Would this work to slick my babies hair back?

I don't wash my hair every day & need a gentle-to-the-hair gel that I can use when my hair is already dry. Will this work?
