The soft tissue envelope of the cranial vault is called the scalp. The scalp extends from the external occipital protuberance and superior nuchal lines to the supraorbital margins. The scalp consists of 5 layers the skin, connective tissue, epicranial aponeurosis, loose areolar tissue, and pericranium. The first 3 layers are bound together as a single unit. This single unit can move along the loose areolar tissue over the pericranium, which is adherent to the calvaria
The skin of the scalp is thick and hair bearing and contains numerous sebaceous glands. As a result, the scalp is a common site for sebaceous cysts.
Connective tissue (superficial fascia)
The superficial fascia is a fibrofatty layer that connects skin to the underlying aponeurosis of the occipitofrontalis muscle and provides a passageway for nerves and blood vessels. Blood vessels are attached to this fibrous connective tissue. If the vessels are cut, this attachment prevents vasospasm, which could lead to profuse bleeding after injury.
These blood vessels can cause issues if pigment enters at the correct depth. The result can be spreading migration over time. If you tattoo deep enough into the fibrous connective tissue you will get migration and possible large dark spots.
There are nerves to consider, Supratrochlear nerve ,Zygomaticotemporal and Auriculotempora if someone does not understand how these nerves work and poorly tattoo the scalp you can possibly cause physical issues.
Every liquid substance on earth has a pH, or an acid-base, measurement. Very few substances are neutral; most are either acidic, such as vinegar, or basic, such as bleach. Human beings are no exception to this rule, having a pH balance of about 5 on the skin, including the hair and scalp. This low, or acidic, pH works as a protective mechanism, as germs cannot thrive in the acid.
The PH of the scalp can be a huge issue, some people with dandruff use chemicals to prevent the condition, many people with this condition do go bald, these chemicals in shampoo can affect the inserted pigment by entering the skin and causing bluing or graying of the pigment particles. Some use what is called Charcoal pigments claiming they are the best and do not use Iron Oxide, Charcoal is known to have very high carcinogen levels and particle size is difficult at best for the manufacture to control.
Personally I study the science of the issues and try and solve the issue but like vitiligo there are issues to be considered and this type tattooing takes more than buying pigments with fancy claims. The fact is we never truly know what the human body might do with a something that should not be there in the first place.
There are things in cosmetic tattooing that can be done to help resolve issues, this type of tattooing can be done but it takes more than just a needle and pigment, numerous conditions must be right to get a good result!
I will continue with more information within the next few days! Bottom line is do not believe all the BS that some of these manufacturers make or some of these schools… frankly, they are full of it!
