Does hair dye or gel affect ghusl?

It depends on whether the product blocks water. Hair dye usually only colours the hair, so it does not affect ghusl. Hair gel, wax, spray and other heavy styling products can form a waterproof layer, and if that stops water reaching your hair or scalp, you should wash it off first.
What ghusl needs
Ghusl requires water to reach the whole body, including the hair and the skin of the scalp. The Prophet ﷺ would run his wet fingers through the roots of his hair and then pour three handfuls of water over his head (Sahih al-Bukhari 248). When Umm Salama asked whether she had to undo her tight braids, he told her three handfuls of water on her head were enough (Sahih Muslim 330). The condition is that the water reaches the scalp.

Allah wants this to be easy for us:
Products that do not matter
If a product only changes the colour or leaves the hair soft, there is no problem, because water still reaches the hair and skin. Whether dyeing is allowed at all is a separate question. See Can I dye my hair?
- Hair dye and bleach: they colour the hair and do not form a layer on top. Your ghusl is valid.
- Henna: same as dye. It leaves a stain, not a barrier.
- Conditioner, hair oil and leave-in cream: these make the hair slippery but do not stop water from soaking in.
Products to be careful with
- Strong-hold gel and edge control: they can dry into a hard coating on the hair or scalp.
- Hair wax and pomade: thick, oily products can make water bead and roll off.
- Hairspray: a heavy layer can seal the hair.
- Glue for extensions, wigs or weaves: it sits on the scalp and prevents water from reaching it.
The rule scholars give is simple: if something forms a barrier between the water and the hair or skin, it must be removed. If it does not, ghusl stays valid. Extensions and weaves have their own details. See Can I do ghusl with hair extensions?
A practical check
When you wash, pour water over your head and rub your fingers through your hair and scalp. If the water soaks in and the hair feels wet to the roots, you are fine. If the water beads up and runs off, shampoo your hair first to break down the product, then pour water and rub again. You do not have to remove every trace of product or colour, just anything that blocks the water.
If you often doubt whether the water reached, trust that a normal, thorough wash is enough. See How do I do ghusl?
- Water must reach the hair roots and the scalp in ghusl (Sahih al-Bukhari 248).
- Dye, henna, conditioner and oil do not block water, so ghusl is valid.
- Heavy gel, wax, spray and glue can form a barrier, so wash them off first.
- Shampoo breaks down stubborn products before ghusl.
