Dermaroller for scalp area

[Salman]

Hi Sarah,

I recently started using the Dermastamp on scar tissue around my face as well as the 0.5mm Dermaroller on my face (larger areas) and scalp for treatment of thinned out hair.  

I was wondering if there are any plans to introduce a larger dermaroller for bigger coverage of the scalp in one go as it takes up considerable time to treat the scalp in the directions as recommended using the small head of the 0.5 mm Dermaroller?

No, because the more needles a roller has, the more pressure you need to push them in, so there is a limit to the number of needles you can have in a roller head..
