Male M-shaped correction
The hairline that everyone has is called a hairline.  In particular, correcting the wide part of both ends of a man's hairline is called M-shaped implantation. It is a type of hair transplant that increases satisfaction by changing the design and height of the M-shaped area in the direction desired by the patient using the hair of the back of the head.

Surgery information


surgery target

Those who want to correct the letter M


Required parameters

​Average male 3,000-4,000 hair


surgery time

about 5-7 hours


recovery period

3-4 days (based on swelling)


Collection method

incision, non-incision


Transplantation method

PRP, DNA, Stem Cells

1) incision

  • surgery time is short

  • Only those with sufficient scalp elasticity for suturing

  • Only a thin solid line remains after the incision is sutured.

  • Maintaining the hair density within the unit area of the occipital region after surgery

  • Stitch removal on the 10th day


2) Non-incision

  • Surgery time is relatively long

  • Not affected by scalp elasticity

  • A white dotted scar is formed on the back of the head, which fades over time and cannot be seen unless you look for it.

  • Punch diameter is small, so there is not much tee, but the density of hair in the unit is slightly reduced

  • cost more than incision

Check for disease

1) Diagnosis of hair loss

If you are experiencing a hair loss disease, it is recommended that you do hair loss treatment first before transplanting.

Hair loss diseases such as alopecia areata or seborrheic dermatitis will eventually recur if the abnormal immune response is not restored or the inflammatory problem is resolved, making it difficult to engraft hair follicles. In this case, in principle, treatment takes precedence over hair transplantation.


2) Scalp Diagnosis

You need to accurately judge your scalp elasticity, hair density, hair type, etc.

3) blood test

Basic disease and physical condition must be checked.  (Check whether surgery is possible due to diseases including liver, kidney, thyroid, cholesterol, anemia, etc.)  It is also a necessary test to check whether there is any difficulty in prescribing antibiotics and hair loss drugs after surgery.



The design that the doctor decides is important (※ the opinion of a doctor with long experience is also important)


1) Design

  • Set the reference point to have a balanced hairline by the golden ratio

  • Basically, the shape of the M shape is maintained, but the deep M shape is filled with a light M shape.

  • Side line symmetry and peak design considering the facial contour and eyebrow position

  • Strategically placed hair follicles & calculated hair density in various areas

2) motherfish

  • Hairstyles are different for each person/part/part/part/kiln, etc.

  • Accurately grasp the wool by using multiple parts

  • Matching surrounding hair and hairs during transplantation

  • Transplanted to the inside where it grows well for a natural connection with the existing hairline

3) Engraftment rate

  • Hair follicle damage (hair follicle amputation rate)  should be low

  • Controlling the depth of hair follicles during transplantation

  • It is important to manage swelling and inflammation before and after surgery

  • Improving engraftment rate with growth factors, nucleic acid components, and hair loss drugs

safe surgery


There are several points to check in order to have a safer operation.


Is the doctor in charge directing the operation?

Surrogate surgery problem


About anesthesia

Whether propofol is used


Is it safe to harvest?

Do you follow safety precautions for incision and non-incision?


Do you have transplant know-how?

Less pain and swelling after surgery

1) Is the surgery performed by the surgeon himself?

Whether a ghost doctor or nurse's surrogate surgery is an issue these days


2) Matters about anesthesia

You need to know whether propofol is being used or not. Propofol is derived from soybeans, so people with soybean allergies are at risk of breathing problems

3) Is it safe to collect?

The incision method accurately identifies the softness of the scalp and the required parameters, and determines the length and width so that no scars are left and there is no wastage of hair.

In the non-incision method, if a punch with a diameter that is too thin or too large is selected, the engraftment rate may decrease or a large spot scar may occur after surgery.

4) Is there any transplant know-how?

It is important how little pain and postoperative swelling is during surgery. If the swelling is severe, it may not only interfere with daily life (such as commuting to work), but also reduce the engraftment rate.

rich experience

Guarantee of hospital responsibility


Even after the surgery is over, you need to check whether you are responsible for the results of the surgery.

1) Is there free augmentation surgery?

After the surgery, when the time for engraftment and growth has elapsed, it is necessary to find out whether reinforcement surgery is provided for free of charge in the area with a low engraftment rate.


Accurate hair loss diagnosis


Based on the experience of performing hair loss treatment and hair transplantation for over 10 years, we have researched only hair.


honest care


Hair transplantation is not recommended for patients who prioritize hair loss treatment.

We suggest the appropriate collection method and number of hairs in consideration of the patient's scalp condition, elasticity, and hair density.

If you have a physical condition or unstable condition by conducting a preliminary examination such as a blood test, we suggest that you do not proceed with the operation or postpone the schedule.


In other cases, if the need for surgery is low or it is difficult to see the effect, the patient is persuaded and returned.

safe surgery
At Mori Clinic, 100% of all procedures, including anesthesia, transplantation, design, hairline transplantation, and post-transplant swelling care, are performed by Dr. Sang-wook Lee.

1) All in One system

From anesthesia, transplant design, hairline transplantation, and post-transplant swelling care, all procedures are performed 100% by Dr. Sang-wook Lee.

2) Safe anesthesia system

  • The operation is safely performed under local anesthesia without using propofol, which may be dangerous, and using safe drugs such as midazolam under semi-sleep anesthesia while maintaining the patient's consciousness.

  • Semi-sleep anesthesia: Local anesthesia is performed in a semi-conscious state, that is, in a state of being able to talk, so that the patient is pain-free and fearless. All procedures are as comfortable and pain-free as possible so that patients can relieve the burden of surgery.

  • The patient's blood pressure, pulse, and oxygen saturation are monitored in real time throughout the operation.

1) No shave

In the case of incisional transplantation, both the occipital region and the recipient region are not shaved, and the patient's satisfaction is high as there is no scarring after transplantation.


2) No pain

Because the operation is performed through a dual action of partial sleep + local anesthesia, there is almost no pain.

3) No swelling

Mori Clinic provides relief from swelling before and after surgery and improvement of engraftment rate through 3 methods (PRR, DNA, and stem cells).

4) No propofol

Propofol is soybean. In other words, it is extracted from soybeans, so if a large amount of propofol enters blood vessels in people with soybean allergy, it can be dangerous due to respiratory difficulties, so Moriwon does not use propofol.

5) No scars

Because the edges are well aligned and sutured to avoid inflammation, it leaves almost no scars unless the skin quality is good.


Follow the principles of the collection guidelines



Adhere to a range that does not overdo it with an average width of around 1.5cm per operation


Maintains punch size and angle to minimize non-incision scars

Transplantation method


At Mori Clinic, there are PRP, DNA, and stem cell transplantation methods.



A method of collecting blood about one syringe, putting it in a special kit, separating and extracting growth factor platelets through centrifugation, and using it for transplantation



It is called nucleic acid transplantation, and a method of concentrating a material composed of nucleic acid components in the cell nucleus and using it for transplantation.


Stem Cells

A method of using stem cells (original pluripotent cells) in the body of the transplant recipient

1) PRP transplantation

This method is used for transplantation by taking blood from about one syringe, putting it in a special kit, and separating and extracting growth factor platelets through centrifugation.

  • We use the latest high-end centrifuge

  • We use the latest and highest quality PRP KIT.

  • higher fertility rate

  • less swelling

  • recovery is fast

  • There is little damage.

  • Platelets and growth factors are collected at high concentrations.


2) DNA transplantation

It is called nucleic acid transplantation, and a method of concentrating a material composed of nucleic acid components in the cell nucleus and using it for transplantation.

  • Excellent cell regeneration ability

  • Complex ingredients such as nucleic acids, growth factors, and cell factors

  • The engraftment rate is higher than that of PRP transplantation.

  • Recovery is faster than PRP transplantation

  • Less swelling than PRP transplant

  • There is little to no scalp damage.

  • You can quickly return to your daily life after surgery.

3) Stem Cell Transplantation

This method uses stem cells (original pluripotent cells) in the transplant recipient's body, and the engraftment rate and scalp recovery are better than DNA transplantation. In addition, by using one's own stem cells, the possibility of unnecessary immune or inflammatory responses is slim. In particular, in the case of stem cells (pharmicells) used after culture, although expensive, they are manufactured through a national testing institution and are safe and when injected into the human body, anti-aging, hypertension, diabetes, liver function improvement, skin improvement, energy enhancement, chronic You can enjoy excellent effects such as fatigue, etc.

  • Stem Cell Extraction from Spinal Cord

  • No pain during extraction

  • No need to remove stitches

  • The engraftment rate after stem cell hair transplantation may be 100% or more.

  • (If two or more can come out of a place once planted)

  • best fertility rate

  • No scalp damage

  • no swelling

Hair transplant responsible for the end


In order to increase satisfaction with hair transplantation, Mori Clinic guarantees free augmentation surgery for any part where the engraftment rate feels insufficient after one year of surgery.
