Can you recommend a mild gentle hair relaxer for soft curly but thick hair?

Okay I know exactly what you need okay my hair is brown and is extremely wavy and thick and curls therefor i use pureology which i got at Fred Meyers and it cost 28.00 but i gaurantee it will work it works so well u just need less then a penny sized drop and it makes your hair smell and feel terrific where i can go to sleep and not have to worry because when i wake up i don't even have to brush it
