I tried it, and decided it is not for me. Combs only thin your hair if you are steady tearing your hair out with them. Some peoples hair really thrives without combs, but that doesn't mean we should all throw ours down.
When I straighten my hair, the only thing afterwards that I do until the next wash (and this is for a week) is rub coconut oil on my scalp and hair every night before cross wrapping and putting a scarf over it. Then every morning I comb it with my Jibere shower comb, add a few drops of coconut oil and go. If I didn't have that comb... my shed hairs would be matting and tangling with the rest of my hair and my ends would tangle and catch and break or split.
Basically when I follow this regimen and use my comb, the only thing that comes out is shed hairs, no breakage, nothing.
Now when I go without a comb for long periods of time my shed hairs do get tangled, my ends wrap around eachother, my hair starts breaking from not being touched everyday... and I wind up with matted, mushy hair the next time I wash. Even if I don't straighten my hair it is particularly important for me to at least use my Jibere comb on my ends once or twice a day to keep them in check and from tangling. Low manipulation and not combing is cool if you're a 2 or 3 or something... but if you have 4a coils and 4b kinks and you're trying to keep your hair, it is probably not a good idea to just leave it alone everyday without detangling. Maybe not use a fine tooth comb, but something... and my jibere comb and coconut oil (for extra slip) is that something... IMHO
