Is the home IPL hair removal device really capable of permanent hair removal? - Nobel Innovation

When most people choose the method of hair removal, the first thing is to see how the hair removal effect is, whether there is residue, and then the length of hair removal time. Now there are some hair removal products that can be permanently removed. There are definitely many people who have questions. Is it true? Let Nobel Innovation talk to everyone today.

In the current method of hair removal, the four words of permanent hair removal are the two products of laser hair removal device and IPL hair removal home use device. Can the photon hair remover permanently remove hair?

Let's talk about the hair growth cycle first.

The growth of hair is cyclical and is divided into growth period, regression period and rest period.

Growth period: The hair growth in the growing period is 0.27~0.40mm per day for 2-7 years, characterized by continuous growth, and then enters the regression period.

Degenerative period: After entering the degenerative period, the hair bulbs in the lower part of the hair follicle including the hair growth part begin to shrink. The hair no longer grows and becomes loose and tends to fall off; the hair in the regressive period accounts for about 1%; usually 2 to 3 weeks, and then enters the rest period.

Rest period: During the rest period, the lower part of the hair follicle is completely atrophied, the hair is shed, and the hair in the rest period accounts for about 14%; the rest period lasts for 3 to 6 months, and then the hair follicle enters the growth period, and new hair grows.

After talking about the growth cycle of hair, let's talk about the principle of laser hair removal device and IPL hair removal home use device.

IPL hair removal home use is a selective light (wide spectrum technique) pyrolysis principle using a strong pulsed light source to achieve hair removal. IPL hair removal home use is a gentle, non-invasive treatment of the laser inside, which uses the melanocytes in the hair follicle to absorb light in a specific band, causing the hair follicle to generate heat, thereby selectively destroying the hair follicle while avoiding damage to surrounding tissues. Remove hair.

Laser hair removal method is based on the selective photothermal dynamics, by properly regulate pulse energy of the laser wavelength, laser light through the skin surface will be able to reach the roots of the hair follicle, absorption of light energy into thermal energy and destruction of hair follicles, thereby the ability to regenerate lost hair at the same time without damaging the surrounding tissue, pain slight technology.

Laser hair removal is a permanent form of hair removal that can damage or destroy hair follicles.

However, the hair is likely to grow again. If the hair follicle is damaged during laser hair removal but is not completely destroyed, the chance of hair growth is high.

Therefore, many doctors now use laser hair removal as a permanent hair removal rather than permanent hair removal.

If the hair follicles are already necrotic, hair removal is permanent. If the hair follicle is only damaged, the hair will grow again. The length of time that hair grows again depends on the hair growth cycle that is unique to each individual.

Therefore, permanent hair removal is a small probability event. Under normal circumstances, the IPL hair removal home use device can not do permanent hair removal, at most, you can only make your hair growth cycle longer.
