3-4 inches with straighter hair is a bit too short. My advice to you is to wait a few more months until your hair is 6 inches long, or else you’ll have an uphill battle trying to force your short hair to stay together.
So regardless of your starting method, you will have trouble until your hair is a bit longer. (By the way, you can read the pros and cons of several starting methods on our “starting methods” page!)
On afro textured and very coily hair, locks can be set up starting at about 1-2 inches. However for straighter hairs, locks must be started with more length.
While you’re waiting for your hair to grow, you should carefully read as much information from our blog and other trusted sources as possible. The best thing you can do before you start locks is to arm yourself with knowledge, and we provide quite a lot of it here!
I hope this is helpful!
