Bored in office- there’s a separate Issur to have Chometz in your home, even if you don’t eat it. Otherwise we wouldn’t go through all that work to clean. We would only refrain from eating bread for 8 days!
You should check all your toiletries, skin care, and cosmetics that they’re Chometz free.
Chometz ia assur in hanaah (pleasure) as well…….. not just eating. That is why beer base shampoo and certain alcohol in some deodorants is not permitted.
I would check Tresseme carefully because I know that the shampoo usually isn’t good. It has wheat in it. I don’t know about the hairspray but I think it should be checked and not assumed that it’s good.
Yolk- that’s a very general statement to give here. There might be some good companies, yet others may be Chometz. Everyone has to check whatever brand they own.
