When it comes to hair, people always think of [3,000 worry silk]. However, if this head of hair is sparse or completely lost, that is the real worry. Today let’s talk about this [top priority].
Human hair is mainly divided into thick terminal hair and fine filiform hair. These hairs with different shapes have the same structure, i.e. Hair follicles in the skin and hair shafts extending out of the skin.
Why do people lose their hair?
As the saying goes, hair, like grass, goes through a periodic cycle of growth, rest and degeneration. In normal scalp, hair follicles are distributed in a certain proportion at each period, so new hair and shed hair maintain a dynamic balance.
Our most common alopecia can actually be understood as [grassland degradation] on the scalp-either due to poor soil or man-made destruction.
- Poor soil: refers to the physiological environment of the human body is not suitable for hair follicles to grow thick hair, such as androgen alopecia. Artificial damage: refers to hair follicle damage caused by burns and scalds.
When did what consider hair transplant?
Androgenic alopecia can be treated with drugs, which can kill two birds with one stone for patients with benign prostatic hyperplasia at the same time.
If the drug treatment is ineffective or alopecia is caused by scars, hair transplant is required.
However, hair transplant is not suitable for all people.
Alopecia caused by scar, hair transplant effect is not good
Hair transplantation technology is very effective for hormone-induced alopecia, but if the scalp is burned extensively and the blood supply to scar tissue is not good after wound healing (which can be understood as [poor soil]), the transplanted hair follicle is difficult to survive. In this case, an expander can be used to expand the normal scalp with hair around it and repair the scar scalp.
If the scar area is small and the scar tissue is superficial, a small number of hair follicles can be transplanted many times, but the survival rate after transplantation will be slightly lower.
Hair transplants are like transplants
When transplanting hair, first cut a scalp from the back of the head and separate hair follicles under a magnifying glass, just like the [saplings] selected from the nursery.
Then poke holes in the parts to be transplanted, and then insert hair follicles evenly with a certain density to complete the transplanting of hair follicles. After the operation, the transplanted area is properly protected, and the [saplings] can grow into [towering trees].
Through hair transplant, the hair is redistributed, and the appearance of the patient’s hair is improved without adding a hair to the patient during the whole process. Therefore, hair transplant is only a shaping method, not a hair growth method.
The reason why the scalp is cut from the occipital part is that the scar is very hidden and the hair follicle activity in this area is better.
Does hair transplant have adverse reactions to what?
Hair transplantation has little trauma, as long as there are no basic diseases such as hypertension, diabetes and coagulation dysfunction, and the skin in the operation area has no infectious diseases (tinea and various dermatitis, etc.), people can receive treatment.
Postoperative adverse reactions are few, hair follicle survival rate is high, and recovery period is short. As long as attention is paid to postoperative wound cleaning and mechanical stimulation to scalp is reduced, hair follicles can survive quickly.
After hair transplant, will there be hair loss in the hair supply area?
Because the normal hair density is far greater than the density that can be distinguished by human eyes, that is, the hair density is less than the normal value within a certain range, and the appearance effect of [thick hair] can still be maintained.
Therefore, only a small amount of hair needs to be transplanted in the hair transplant process to produce better visual effects and will not lead to hair loss in the hair supply area.
In general, there will be no obvious scar in the hair supply area. Because the incision of hair transplant is very small, only a thin scar will be left hidden in the hair after healing, which will not affect the appearance.
What are the shortcomings of hair transplant?
Although hair transplantation has many advantages, it also has inherent defects.
For example, the newly-born hair of androgen alopecia patients may still fall off and be sparse after hair transplant, which needs to be assisted by finasteride. In addition, this technology itself belongs to [demolishing the east wall and mending the west wall]. If the area requiring hair transplant is large, the effect may not be satisfactory.
What is an allogeneic hair transplant?
If the alopecia area is large and the autologous hair follicles are insufficient, allogeneic hair transplantation can be considered.
This [allogeneic] is not to transplant other people’s hair follicles, but to insert some natural or artificial fibers (silk, nylon and other fibers) into the scalp, which is equivalent to inserting fake [saplings] into the ground.
Because for the human body, these fibers are foreign bodies, so there will be adverse reactions of infection and rejection. Even if there is no adverse reaction, these rootless wood cannot remain for a long time and will fall off in about half a year.
What are the hair transplants other than hair?
In addition to hair, eyebrows, eyelashes and beards are closely related to one’s appearance, and the lack caused by various reasons can also be remedied by hair transplantation.
Slightly different is that eyelashes are relatively soft and short in length. If scalp hair follicle is transplanted, newly grown eyelashes may poke the cornea, so hair units are generally obtained from the eyebrow, and the operation method and precautions are similar to hair transplant.
Hair transplant is a surgical technique with a principle very similar to gardening, but it is still [robbing the east wall and mending the west wall], so preventing alopecia is the most positive choice and the only way to protect the fruits of revolution after hair transplant.
First of all, eating less irritating and greasy food can reduce the secretion of scalp sebaceous glands, which is of great significance for protecting hair follicle health.
In addition, sebum should be properly cleaned. Of course, washing hair too frequently and removing sebum too thoroughly will overcorrect and damage hair follicles.
