The Truth About Diode Laser: Is It Really the Gold Standard for Hair Removal?

During the dew season, hair removal becomes a top priority for many people. Traditional hair removal methods are either short-lived or painful, but is the so-called “permanent hair removal” Dior laser technology reliable? As one of the most mainstream laser hair removal methods currently, the diode laser, with its precise wavelength of 808nm, can lock in melanin in hair follicles like a “heat tracking missile”, causing hair to “go without food and harvest”. Clinical data shows that after 4-6 standardized treatments, over 85% of hair can be effectively removed, and the equipped intelligent cooling system significantly reduces pain. However, it should be noted that its effect on light colored hair such as gold and white is limited, making it difficult to recognize like “color blindness”. Although beauty salons often promote ‘once and for all’, it is actually necessary to regularly reinforce it. It is important to choose a reputable institution and professional physician for the operation, otherwise you may end up spending money and suffering. Those who have already completed the treatment say, “You no longer have to worry about ’emergency hair removal’ before a last-minute date.

Unveil the Working Nature of the Diode Laser Hair Removal Machine

The basic treatment principle of semiconductor laser hair removal treatment device is selective photothermal decomposition. The outer hair root sheath in the hair follicle is rich in melanosomes, which can selectively absorb the energy of the laser. The 808nm laser emitted by this device is easily absorbed by colored hair follicles without damaging the surface tissue. The energy emitted by the light is absorbed by the hair and pigments in the hair follicle and converted into heat, thus increasing the temperature of the hair follicle. When the temperature rises to a certain level, the hair follicle will be irreversibly damaged, thus achieving the goal of permanent hair removal.

The growth of hair is divided into growth phase, regression phase, and resting phase. The three periods are cyclical. Laser is only effective for growing hair and has no effect on regressing and resting hair. Generally speaking, hair during the growth period accounts for 1/5 to 1/3, so laser or photon treatment must be performed continuously for about 5 times to completely remove hair.

The Growth Cycle of Hair and Its Relationship with Hair Removal

The growth of hair has periodicity, which can be divided into growth period, regression period, and resting period. Hair in the growth period accounts for about 85% of all hair, and the growth period of hair is 2-6 years. After entering the regression period, the hair follicles in the lower part, including the hair follicles, begin to shrink. Hair no longer grows and becomes loose, making it easy to fall off; During the resting period, the lower part of the hair follicle completely shrinks and hair falls off; The resting period lasts for 3-6 months, after which the hair follicles enter the growth phase and new hair grows out. Due to the slightly different hair cycles in each part of the body, hair removal is targeted at the growth stage of hair, and the cycle alternation takes 1-6 months. The metabolic cycle of the skin also takes 28 days, so hair removal needs to be done 4-6 times, once every 30 days.

The Competitive Edge of Diode Laser Technology

Eliminate the root of the problem

The black hair absorbs heat and spreads it to the surrounding tissues, which can remove the entire hair follicle from the pit end. The effect is generally long-lasting.

Precise and Controllable

During regular operation, it will not damage other skin tissues except for hair follicles. The current laser technology utilizes the principle of extended selective photothermal action, which can precisely control the range of heat diffusion, only burning out hair follicles without damaging the surrounding skin tissue, and has high safety.

High Efficiency

The effective rate of laser hair removal is 90%. The treatment effect of hair on different parts, thicknesses, and colors varies, but even if it cannot be completely removed, residual hair will become thinner and softer, and the growth rate will slow down. According to clinical experience, after three sessions of “freezing point hair removal” treatment, most people can remove 90% of their armpit hair, 75% to 80% of their limb and trunk hair, and 60% to 70% of their lip hair.

Pre- and Postoperative Care Guidelines for Diode Laser Therapy

Preoperative Precautions

Avoid direct sunlight exposure before laser hair removal. Do not shave your hair before the first treatment, so that the doctor can evaluate the effectiveness and develop a treatment plan. During the first 6 weeks of laser hair removal, hair should not be removed, and products such as beeswax and hair removal cream should not be used, otherwise it will seriously affect the effectiveness of laser hair removal.

One day before laser hair removal, the hair removal part can be cleaned with soap, and the use of bath solution should be avoided as far as possible, because part of the bath solution will attach to the skin surface, react with the gel needed in the treatment process, affect the efficacy and may increase the side effects.

If the doctor requires hair removal, a razor can be used to shave it off. People who are pregnant, have scars, or are taking certain medications orally should inform their doctors of their condition and the medication they are using, so that doctors can determine whether laser hair removal is suitable.

Postoperative Precautions

Do not use functional skincare products, use moisturizing and repairing products.

Be sure to pay attention to sun protection on exposed areas.

If the operating area becomes particularly red after treatment, apply ice promptly to reduce the redness.

When using laser hair removal, do not use other methods for hair removal at the same time.

Effective Clinic Reactions After the Treatment

The operating area is slightly red and warm

The root of the hair follicle protrudes (like goosebumps), and the hair can be gently removed with tweezers

You can smell the smell of burnt hair

Some customers have very little hair and light colors, making it difficult to react in this way. The operating area is slightly red, and customers feel a sense of warmth when they feel it.

Q&A

Q: How many times should hair removal be done and how long should it be separated?

A: There are three stages in the hair growth cycle: growth period, regression period, and dormancy period. Only hair in the growth period can be effectively removed. The three growth cycles of hair alternate, and the length of each cycle varies in different parts of the body. After extensive clinical research, the hair removal interval is 30 days, and the hair removal rate is the highest, requiring 4-6 complete removal.

Q: Do thicker hair require more optical hair removal?

A: No, hair removal is not determined by the amount of hair. Depending on the hair growth cycle, generally 4 to 6 hair removal treatments can permanently remove the hair.

Q: What season is more suitable for hair removal?

A: Hair removal is wound free, does not require a recovery period, and can be treated at any time. Theoretically, it is non seasonal. However, hair removal requires multiple treatments, so it is recommended that you seek treatment as soon as possible so that you can wear summer clothes and showcase your beauty freely in the summer!

Q: What are the reactions of the skin after hair removal?

A: After receiving treatment, there may be a slight redness, which will subside after a few hours and will not cause skin damage or affect work and normal activities.

Q: Will hair removal affect sweating?

A: It won’t. Hair follicles and sweat glands are two independent structures, with hair growing from the follicles and sweat glands located next to the follicles. They are not the same thing. The process of hair removal only destroys the growth cells of hair follicles and does not affect sweat glands or sweating.
