1 Mr. Liu asked: I am 30 years old, so I am not old enough to lose my hair, but a year ago I had severe hair loss, which affects my beauty. I heard that autologous hair transplantation can make the lost hair grow out from new, I would like to consult experts, is autologous hair transplantation suitable for anyone? Will there be any adverse reaction after transplantation? Hello Mr. Liu, the issue of hair transplantation is also one of the concerns of many friends. Hair transplantation (hair drilling transplantation) first appeared during the Second World War and has a history of more than 70 years. Japanese scientists found that hairs carrying intact hair follicles can survive after transplantation and can grow and renew their metabolism normally. The procedure has been continuously developed and improved, and the technique is becoming more and more perfect. With the improvement of American doctors, the technique of perforation, which is often referred to as “plugging”, is used to separate single hair units under a microscope for transplantation of fine areas, such as eyelashes, eyebrows and other parts of the reconstruction, greatly improving the scope of application and success rate of hair transplantation. It can be seen that hair transplantation is not a method of stimulating the regeneration of hair that has been lost, but a method of transferring the surviving hair to the area of hair loss and ensuring its survival. Its scope of application can also be deduced from the fact that firstly, there must be enough donor hairs to choose from, and secondly, the skin of the transplanted recipient area must have good blood flow and nutrition, without skin diseases, ulcers or skin defects. The main complications are non-survival of the transplanted hairs, scarring of the donor area and insufficient hair density. The surgery requires a sterile surgical environment, a surgeon with great patience and responsibility, as well as fine operating skills, to ensure good results after the surgery. 2 Mr. Chen consulted: Acne grew on his face two years ago, and was basically cured after insisting on medication, but a lot of scars were left on his face. What is the best way to remove the scars left behind? What should I pay attention to in my daily care? Hello, Mr. Chen, facial acne is the most troublesome youth partner for young people, and often due to their own skin quality or improper care, and cause local pigmentation or scarring, or what we often call “acne scars, acne marks”. In daily care, pay attention to local skin cleanliness, avoid spicy, tobacco and alcohol and other stimulating food intake, avoid external stimulation of irritating chemicals, and most importantly, avoid artificial squeezing to prevent local infection. When the corresponding problems appear, you can seek medical consultation and early treatment, for scar prevention is more important than treatment. Because the formation mechanism of scarring is very complex, once it appears, it is impossible to disappear completely. Of course, once acne scars appear, do not be anxious. You can use appropriate methods to make the texture softer and the color closer to normal, and eventually make the appearance less obvious. For newly formed scars, especially those that are proliferating and above the skin surface, topical treatment with anti-scar medications can be used to inhibit the proliferation of the scar. For acne scars that have already formed, two main types of treatments can be used: laser and microdermabrasion treatments and surgical treatments. The traditional surgical treatment, also known as abrasion, was first invented and used in Europe and the United States by our plastic surgery expert, Mr. Song Ruyao, but its application was limited due to its tendency to produce local pigmentation problems in Asian people. At present, laser treatment for acne scars and marks is widely regarded and respected for its non-invasive, minimally invasive, less painful and less complications, especially the Bait Laser 2940 fractional treatment, which better reduces the appearance of pigmentation. Laser treatment can generally choose phototherapy first to improve the skin acne scars and pigmentation-type problems, after which for acne scars, especially depressed acne pits, fractional or grinding treatment with fractional laser can improve the local appearance. 3 Ms. Liu consulting: not long ago on impulse to tattoo, now want to remove the tattoo. Want to consult experts, tattoos can still be removed? With the laser effect is not better? Ms. Liu, tattoo is a double-edged sword, that is, can bring happiness, will also bring pain, and sometimes seriously affect their own image, resulting in work, life inconvenience, causing a serious psychological burden. Tattoo according to the treatment and the use of different color materials can be divided into traumatic tattoo, life tattoo and professional tattoo three categories. Tattoo treatment is currently based on laser and surgical treatment, of which the laser is a chance to non-invasive repair tattoo method. The effect of laser treatment is mainly related to the color used and the level of tattooing. Life tattoo generally refers to the use of common coloring materials in life (pen water, ink, etc.) by non-professionals, or by their own tattooing. Therefore, the level of tattooing is generally shallow and mostly a single level, so the effect of laser treatment is more ideal. Traumatic tattoo is due to trauma caused by foreign objects (sand, cinder, etc.) caused by implantation, implantation of foreign objects containing more metal components, laser sometimes difficult to completely remove. Professional tattoos are mostly used with color dyes (especially imported professional dyes) multi-level three-dimensional tattooing, especially multi-color composite tattoo friends, the effect of laser treatment are not very ideal. This situation can be treated by surgical methods, including grinding or implants. But these methods will be difficult to avoid causing new damage and scarring. So friends who wish to get rid of tattoos can first choose laser treatment. Of course, for these friends, especially traumatic tattoos and professional tattoo patients, it is more important to choose a professional laser equipment, because you must choose the right wavelength, sufficient energy, or even multiple devices in combination to achieve good results. For the laser can not completely remove the tattoo, you can choose the regular hospital consultation, choose the appropriate surgical treatment to be treated.
