Uh oh...out of lurk again (I make good exceptions).
Here's a
pic of some twists using synthetic hair that I did today. Regular old straight synthetic used for braiding. (Freetress Yaki Soft Braid).
Anywho, the client had traction alopecia and wanted kinky twists but I thought she needed a something a bit gentler. Her hair is relaxed, but all hair does the pokey sometime.
Not to knock the suggestion as I'm sure it's effective. Just be very lighthanded with the beeswax. It will seal any moisture out of your hair for a bit. On this client, I used skin grade aloe gel to tame them some but I did NOT clip her real hair. Anytime you see perfectly cleaned up braids or twists, the braider likely ran scissors (or worse flame) along the braid. It's not worth it.
Another option is to skip the Marley Hair (which can be drying and opt for very soft kinky synthetic. Your twists will be sort of funky as seen
here, but I like funky.
It's when the twists look more like something your head sprouted and you don't worry about pokeys at all.
Finally, consider installing extensions on slightly damp hair. It's a little easier to coax the hair to "meld" with the extension hair. You can apply leave in to a section and/or mist with a sprayer OR braid on your hair after you've washed, deep conditioned, detangled, and applied a leave in. It doesn't have to be sopping wet, but braiding on bone dry hair is something I just don't do.
