Should I Buy Hair The Same Length

[summerof1990]

if i get a straight peruvian..
3 bundles..
should the lengths be the same?

why do people get different lengths​

People get different lengths to get a layered look.

I usually buy three lengths so I won't have to cut it.

For instance, for straight hair, I purchase 10, 12, 14. With curly hair, I get 14, 16, 18 inches.

It's all about your preference. Since I like the full ends look, I tend to buy double of the longest length ex 18, 20, 20. If you like the layered look, you could do staggered length (16, 18, 20 or 16, 20, 24).
