I recently got to use these kit.sch Velvet XL Flexi Rods 4pc set in Eucalyptus, here's what I thought... Firstly I love the particular velvet they used it doesn't get or add any frizz and it's so gentle on your hair. The rods are large enough to fit all of my hair and I my hairs length is past my bra strap. Because of the length of my hair it took me a few tries to get it correctly wrapped around the rod but once I got the hang of it it was easy. I didn't like their instructions, they need to be more descriptive, like telling you the instructions are only for voluminous waves, or maybe suggesting you can also twist hair and roll to get beautiful bouncy curls. A few notes, One you need scrunchies to tie off the rod ends and they are sold separately , and they work much better with a bonnet or cap so they don't get frizz if you're sleeping with them in I tried them several ways, Completely Dry Hair no product 4 hours 4/10 Dry hair with a light mist of product(I used a leave in mixed with a bit of water) 7/10 and Wet/Damp hair 9/10 this way works best for longer lasting curls, if you're using no styling products afterwards. In conclusion with Better instructions or suggestions and being used on any damp or wet hair it works amazingly good and I don't have to worry about heat damage!
