Some natural hair clients are scared of a blow dry service using a brush so having a dependable comb attachment is necessary. I paid around $20 USD for this Willie Morrow's Unbreakable Thermo Blow Dry Nozzle, and it was well worth it.
I had to use a real screwdriver in lieu of a jeweler's screwdriver to secure the attachment to my twin turbo hair dryer neck. The nozzle withstood the heat from the dryer, and the teeth did not break. The attachment stayed secure.
There are three different sized inserts to adjust this comb attachment to all sizes of handheld blow dryers.
So you are wondering who benefits from using this comb attachment? The answer: Those with long, resistant, type 3 hair. I do not recommend any type of comb attachment for fine hair nor for short hair nor for hair that is not properly detangled before use.
The client that I used it on had booty length, thick, resistant, type 3 hair. The blow dry service was 1.5 hours. My average blow-dry time for relaxed hair is 20 minutes. So massive thickness and massive length made this unbreakable, heavy duty comb attachment priceless.
In the past, this same client's hair was causing the teeth to break on regular comb attachments. Also, holding onto other "clamp on" blow dry attachments were challenging.
With this natural hair movement, I suggest keeping one of these in your salon tools inventory for those special occasions where a brush will not work due to customer request or otherwise.
