Is this a Keloid scar? Is it not advisable to get a tattoo over Keloid? Any risk in getting a temporary henna tattoo? (Photo)

Thanks for the question, these are wide scars and maybe slightly raised, I wonder if it was tight or if you had an infection. I typically would do a scar revision or I would use a C02 LASER to resurface the area

This doers not appear to be a keloid scar.  If you can find someone that has experience with tattooing over scars, it is possible to camouflage.

Technically, you have a hypertrophic scar.  It might be best to see your surgeon who can revise the scar by cutting it out and resuturing it.  I would try this before tattooing.  A new dressing called Embrace could help minimize scarring.  Please talk to your surgeon about your options.

Based on the photos that you submitted, it does not look like a keloid or hypertrophic scar.  It looks more like a stretched out scar.  The color is likely to lighten over time and become less noticable, some times making it difficult to see.

Looks like a hypertrophic scar rather than a keloid.  You may tattoo over this safely; however, the scar will continue to improve with time and may not be so visible after 12 months.  Maybe it is best to wait than to permanently tattoo something you may not be happy with in the future.

Your scars are widened scars that may benefit from a scar revision. See your surgeon to determine if this is necessary.Keloid scars are raised scars that grow outside the borders of the original incision and often appear to mushroom over the borders. Keloids are common in dark and very light skinned individuals.

NO! These are NOT Keloid scars! Only spread scars... Best to seek IN PERSON opinions if there is anything to be done... 

Your scar appears to be a stretched out scar possibly hypertrophic and not a keloid.  The scar will improve over time.
