Review (5/5): 4C Dream come true
My 4c hair has destroyed dryer combs on the first use so I got in the habit of buying multiple combs at once. After one use I know that wouldn't be the case with this one.
Using it.
I passed the comb through sections about 4x as large as usual AND used more force than I usually do. It didn't bend and I didn't have use two hands to help the comb get through.
Sizing
It took less than a minute to unscrew it and screw it onto my dryer. There are several smaller, removable rings inside that determine the size of the opening. Take out more rings for a larger nozzle or keep them for a smaller one. Then just tighten the one screw. The comb fits on my dryer with no inserts, so if I need to do a quick pass-through on my previously blown out hair, the comb stays in place without the metal ring. I NEED the ring if I'm drying my 4c hair from wet.
Has a tight hold
The slick surface of my dryer allows its included combs to slide off. The metal ring that comes on this comb doesn't allow that. The comb fits on my blow dryer without the smaller inserts. I noticed that if I don't have to use force the comb stays on without the metal ring, but this may not be true on a smaller barrel that requires the inner rings for sizing. I imagine the comb would spin around the rings.
