Her locks are amazing! I think I follow her on IG, too. She is sooooooo sexy!!!
I thought I was subscribed to her YouTube channel but I wasn't until just now. And my bad....I must be all the way wrong and confused. It's a hook but she called it a needle, didn't she?
I was referring to this one in Kris McDred's video (it's been posted upthread before, but I'll just repost it here.) but I'm also legit confused because it looks like a needle to me but he also called it a hook. Unless the point is so small that you can't tell it's a hook and not a needle.
I need an update on this client's locks...cause the first time I saw this video was about three years ago and these locks were dope then. I'm sure they look amazing now, if she still has them. I didn't realize I wasn't subscribed to his channel already either but I am now!
I had to requote you because I realize I didn't address this part of your post before. I'm not sure if using a product will allow them to stay. The locks will come undone as soon as you wash your hair, no? Also, if you tie a knot at the end of the lock, the knots might be big and you might end up with fat tips until they condense. If you're going to tie knots, you have to be sure to tie them extremely tight and be sure about your choice because it would be very hard to undo the knots if you decide you don't like the way that looks.
I would tie the knots loose enough so that you get an idea of what it looks like but tight enough to hold in case you do like it and decide to leave it, if that makes sense. You are also going to have to tie more than one knot, and you'll see what I mean when you attempt this, which will cause you to lose some length. Practice with a piece of yarn or string first so you can understand what I mean before you try it on your locks. I didn't do that, but I'm also cool with it because like I said, I know the length will come back as my hair grows out and I'm happy with the way my locks look. IMO, you can't even tell that I tied knots in some of my locks.
ETA: If you only want to tie one knot on all of your locks, you will have to probably cut all the hair that ends up being below the knot, so that the knotted end will then become the new tip of each of your locks.
The other thing I forgot to mention is if you reconsider and you want to combine them another way, you can always use your interlocking tool to interlock two locks together. I may have already posted the video of DynamicRunner doing this method on her locks, I'm not sure. There were several SLs I mistakenly combined that way when I was first learning how to retighten my own locks. With this method though, you do have to wait until the locks fuse together, and you will end up with two-headed dragons. Then you will need to decide which of the heads you want to cut off so that you end up with one lock. Also, until they fuse, you have to thread both locks through your tool when you retighten.
For me, it always made sense to cut off the shorter head and leave the longer one in tact. You can also save the shorter heads that you cut off and reattach them to the ends of your newly combined locks. I think I was throwing those away, partly because I didn't think to save them for the purpose of reattaching them to the ends of my SLs back then. The other part was due to the fact that my ends were already fat as it was, and some of the dragons I was cutting were not the same size and I didn't want the huge variance (small from the root to about mid shaft, then fat ends, then a newly reattached, smaller end.) So if you can picture it, it would have looked like this:
-------------------------------0000000000000000000============
instead of this:
--------------------------------000000000000000000.
I'm not even sure reattaching would have worked anyway, because my bunching on the ends felt like stone. I don't think a crochet needle was going to get through that.
