Does the One Upper damage your hair?

A: All heat applied to hair can cause damage. However, it is a lot safer for your hair to go from curly to straight hair using the brush because you are not ironing hair between two plates.

Is there a guarantee?

A: We offer a 10 day money back guarantee. Purchase select products - if you like it, keep it! If you don’t, you have the option to send them back for a refund. Please see the Warranty/Shipping and Returns Page.


What is the max temp on the One Upper?

A: Our brush has many levels of temperatures you may set it at for your hair type! The lowest temp is 125℉, and the max temp is 450℉.

Does this brush plug in or use batteries?

A: It uses a US safety plug, so it plugs into an outlet. 

Do the bristles break?

A: Yes they can because the bristles on the sides are made of plastic that soften as the brush is heated. If you brush your hair and section it before using you will not break off the bristles. The bristles on the side are used as a heat barrier from the heated bristles on the interior of the brush. The brush can be used if the bristles break; you just need to be aware of areas like your ears. Please be gentle with the brush. Go slow! 

Can I burn myself?

A: Yes! The brush is a heated appliance, just like a curling iron or flat iron. Please use caution when using the brush not to touch the ceramic with your hand while the brush is turned on. There are heat protectant tips so you don't burn your scalp with use! You can put your hand to the brush, and it has a barrier.
