Modern doctors can benefit from the use of laser and laser power in a variety of aesthetic operations due to technical improvements. Similarly, laser can be used in hair transplantation.
The hypothesis behind laser treatment for hair loss, also known as red light therapy, is that low-dose laser treatments stimulate circulation and encourage hair follicles to grow hair. You could interpret it as a reactivation of dormant cells to promote hair growth.
So, laser hair transplantation is a non-surgical therapy that helps people regenerate their hair. It has a major impact on both men and women. The procedure is carried out using a high-tech equipment that emits gentle, low-light illumination. The laser light penetrates and activates the cells and tissues of the scalp. The technique inhibits the DHT hormone, which is the primary cause of hair loss. Furthermore, red laser lights increase blood flow to the area. The red wavelength between 670 and 630nm gives the appropriate frequency to restart the new hair development cycle.
Throughout a laser hair transplant, also known as laser hair therapy, lasers make holes on the head for recipient sites, and you may experience some pain during the process, but it will be transitory. On the other hand, while producing those holes on the recipient sites, no damage is done to the surrounding tissues. However, if no local anesthetic is used, the surgery will be quite uncomfortable. As a result, thoroughly numbing the operative area is critical for the patients. And also, hair shedding will continue in the following years if a hair transplant treatment is not completed correctly, as it is with other surgeries. Furthermore, the patients may have scarring or a slow recovery phase.
So, selecting your surgeon is a vital point at these points if you do not want any scaring or severe pain during and afterwards the surgery.
You may be wondering what you will get from laser hair transplantation at this point, so here are some advantages;
- Cell metabolism will be stimulated.
- The treatments address scalp concerns such as dandruff.
- The scalp’s blood flow will rise.
- Scalp inflammation will subside following surgery.
- DHT hormone will be limited.
- There will be no adverse consequences.
- Hair follicles will have a better chance of survival before and after surgery than ever before.
- To accept the donor grafts, no significant incisions or punches are required.
Similarly, you may want to know the side effects of the procedure. If so, here are certain side effects;
- Some individuals may have swelling, redness, or irritation following surgery, although these side effects can be minimized with laser hair transplant.
- The use of laser on the scalp is restricted because the beam may cause harm to any neighboring follicles, and it is also restricted since there should be substantial space between existing transplants and fresh grafts.
- The methods may be less helpful for persons in the final stages of hair loss than for those in the early stages of their hair loss.
- Certain medications you are taking may interact with the treatment.
- Laser hair transplants should not be conducted on persons who are using photosensitizing medicines.
- Laser technology must be used with extreme caution; otherwise, negative outcomes are unavoidable.
To sum up, with its pros and cons, laser hair transplantation is a novel method to help you with hair loss issues. You can get the best information from an expert in this field.
Do lasers really regrow hair?
A range of laser hair growth therapies have lately become available. Plenty of them make use of clinical lasers to trigger hair follicles, with promises that frequent laser treatment can enhance oxygen and nutrition delivery to your hairs. The majority of laser hair regrowth technologies function by sending light into the head. Despite the lack of scientific evidence, supporters of laser treatment think it can improve blood circulation and increase hair development. At the current point, there is insufficient high-quality medical evidence to clearly determine whether laser hair regrowth therapies are successful or not.
How quickly does new hair grow?
Following the surgery, your skull may be quite sensitive. For several days, you may have to take pain medicines. Your surgeon will have you put dressings over your scalp for at least a day or two. Physicians may also prescribe an antibiotic or anti-inflammatory medication for you to take for a few days.
The transplanted hair falls out and after 2 to 3 weeks of surgery, and you should observe new shoots in few months. After 4 – 6 months, the majority of patients will notice 60% new hair growth. Some surgeon recommend minoxidil, a hair-growth treatment, to enhance hair growth following transplantation, although it’s unclear how well it works.
