Generally, tattooed hair is mostly hairline, or in the case of sparse hair, you can also face obvious scars on your head or hair transplant failure. These problems can lead to thick hair, covering the scalp or scars after tattoos. However, some people do not recommend tattooing hair, for example, hair is extremely rare, or hair loss is very serious, and there is no hair in a large area. Because it is a tattoo after all, it is not as real as a hair transplant. It's okay from a distance, but it's just a dark color on the scalp at close range, which will make people more embarrassed.
There are other reasons besides being untrue. For example, tattooed hair is a kind of injury to the scalp, and many people know it. Because it needs to be injected into the scalp skin and colored, just like eyebrow tattoo eyeliner, but it is a small area, and tattooed hair is usually a large area, so it is harmful to the scalp. At present, some tattooing institutions are not formal, and there are no relevant procedures and permits, so there are problems with qualifications and sanitary conditions. In this case, infection and inflammation are more likely to occur when tattooing. In addition, the technology of hair tattoo is also an aspect that needs to be considered.
Of course, if you can avoid the above situation, you can still find a tattoo in a regular institution.
