Microneedling is an excellent way to restore the hairline to its former glory. The study above shows people doing minox vs minox + microneedling and the microneedling control group had much better hair restoration.

You shouldnt use the typical derma-roller but rather the dermastamp or even more ideally the derminator pen.

Dermastamp link

This is a budget option but it optimizes the entry angle of the pins rather than the dermaroller wrecking havoc with its dogshit entry angle.

The dermastamp causes far less irritation meaning increased recovery. Its also MUCH easier to keep sanitary which is important especially if you are considering derma stamping/micro needling the face which I will discuss in another section of the guide.

MOST IDEAL

The Dr Pen is quite good, but ill be honest they are all practically the same dropshipped devices from Aliexpress so the brand is pretty irrelevant. The idea is it is much more effective at its task of microneedling effectively.

Regimen

You dont need many sessions and especially not much frequency for maximum benefit. The optimal length for microneedling hairline is going to be 1-1.5mm. Remember the bigger size you use, the longer your recovery. I recommend 1.5mm every 4 days.

ALWAYS SANITIZE AND DONT USE TOPICAL MINOX IMMEDIATELY BEFORE/AFTER!
