How bad are the marks or scars of the micro blades ?

Any cut on your skin will leave a scar. How visible these scars are depend on how your body heals.  If your body is prone to scarring, then even "micro-blades" can leave "bumps" and scars.

Dear houssam23Thanks for the question. The recipient sites don't heal up with holes. They close up and heal without appearance of a hole.When I explain this concept to my own patients I use the analogy of getting your blood taken when you get blood tests or when you get an intravenous put in at the hospital. These needles are much bigger than what we use in hair transplantation - 16 gauge, 18 gauge or 19 gauge. When you look at your arm months later (at the spot where you had the needle) , you don't see any evidence of the hole where the blood was taken from. The same is true for the scalp. These little holes are even smaller and heal without evidence of the little holes. I hope this helps.

what you are describing may not be as a result of blades. You need to contact your doctor and get his advise.
