Q. Can hair loss be improved immediately?
There may be individual differences in efficacy, and Medihair's treatment method, low-power laser therapy, is effective when used consistently for a long period of time (more than 4 months).
(Complete 16-week clinical trial targeting 46 adult men and women at S Hospital / 21.64% improvement in hair density / 19.46% hair thickness / Ministry of Food and Drug Safety approval for efficacy level 3 medical device safety)

Q. I feel a hot sensation while using it.
Medihair is a product that treats hair loss by activating the overall metabolism of cells, and you can feel heat and sweat in the process.
This is a normal phenomenon. If you feel uncomfortable, please use it after getting enough rest in a cool space.

Q. I am taking or applying hair loss medication. Can I use it?
If you are currently receiving treatment at a hospital, we recommend that you consult with the doctor in charge of using the product.
When applying the applied medication to the scalp, wear it while the medication is sufficiently dry. (If it is not dry, light may reflect and affect efficacy.)

Q. Can I use it when my hair is wet after washing it?
It is recommended to wear it in a clean condition after completely drying the scalp, and when using a dryer, it is recommended to use it after cooling the scalp.
After using Medihair, apply hair styling product to the hair.

Q. Can it be used regardless of age/gender?
Do not use on anyone who cannot express themselves clearly, including infants.
It is also not recommended for use by pregnant, menstruating, or lactating women. (LG Prairie Medi Hair clinical trials are conducted on adult men and women aged 19 to 65)

Q. Will it be less effective if the area being used is covered by hair?
The effect of the hair on the area where it is used has little effect on the effect of Medihair.
Medihair consists of 146 lasers and 104 LEDs.
In the case of lasers, the light energy passes through and reaches the hair follicles even if the hair is covered because the laser travels in a straight line.
In the case of LEDs, they spread widely and help irradiate light energy close to hair follicles.
Medihair helps treat hair loss with the effects of two combined light sources: laser and LED.

Q. Are there any diseases or restrictions that prevent me from using Medihair?
The restrictions (prohibitions) on the use of A-Medi Hair are as follows.
1. If you have a scalp wound or scalp disease
2. For photosensitivity skin such as sun allergy
3. For pregnant women, women who may become pregnant, or women who are lactating.
The following cases require consultation with a specialist when using:
1. If you are receiving skin-related treatment (other than the scalp),
If you have skin disease or irritation
2. In case of malignant tumor, acute disease, high fever, cardiovascular disease, endocrine abnormality, or other physical abnormality.
3. If there is an implant in an area that is touched by an electronic device, laser, or LED installed inside the human body.
4. If you have sensitive skin due to allergies

Q. Is it effective for female hair loss?
LG Pra.L Medihair is a medical device for treating male pattern hair loss and is also effective for women with hair loss.
In the case of female and male pattern hair loss, the symptoms mainly appear as hair thinning starting from the parting area. In this case, activating the hair follicles and scalp cells through Medihair helps to increase the thickness/density of the hair shaft.
(Postpartum hair loss is not male pattern hair loss and recovers naturally after childbirth.)

Q. What is the filling material and how long does it last for?
Charging time is approximately 4 hours and can be used 3 times (up to 27 minutes per charge).
