I 'ono what those products look like, but I think you should not use anything "wet" but should perhaps try an oil like coconut oil. Or maybe if you like Shea butter, that alone or with something like essential oils to make it less thick. The idea is to lessen the shrinkage.
When I use something wet or if I do my puffs immediately after washing and let my hair airdry in the puff, it look like this:
If I use S Curl and baggy overnight in braids to stretch it a bit, I still get some shrinkage and it looks like this:
If I use something dry (although I hate to tell you what I used coz it was a mistake
I had received My Honey Child Type 4 DC and didn't realize it wasn't a leave in so I used it on my hair and didn't like the feel (duh!
) and so added coconut oil)
...then plait it to stretch, the hair doesn't shrink much and I get a bigger puff:
I haven't tried it yet, but I suspect if I just used coconut oil, I'd get a much bigger puff. I think the DC might've caused a bit of shrinkage. If you like grease, or something like it, this is one time when it can come in handy.
