My hair goes from really wavy small waves at the root to big wavy almost straight waves at the end, I have thick hair and it is damaged on the ends. What are some things I can do to keep it manageable?

.Hi!

I'm a wavy, and I can definitely understand different types of waves throughout the hair. Do you blow dry or color your hair? This kind of damage makes the hair straw like and straighter. Maybe this is why your ends are like this?

Like Bikerbraid suggested, keep your ends moisturized with leave-in and oil. You can do a deep conditioning treatment when you can, and snip off the damaged ends gradually till they're all gone
