Treatment Effects
Hair Removal Treatment: After typically 3 to 6 laser hair removal sessions, hair becomes significantly thinner, softer, and grows much more slowly. Most people achieve long-term hair thinning or near-permanent hair removal after completing the course, though different body areas may respond differently to treatment. For instance, areas like the underarms and arms usually show better results, while leg hair, which is often coarser and thicker, may require additional sessions.
Hair Growth Treatment: For hair thinning caused by androgenetic alopecia and similar conditions, hair growth treatments using medications like minoxidil typically require continuous use for 3 to 6 months to show initial results, such as thicker hair and reduced hair loss. Sustained use for 1 to 2 years can achieve more ideal hair growth outcomes, increasing hair density. However, not everyone can fully return to their pre-hair-loss state.
- Hair Removal: Suitable for individuals with excessive hair growth affecting their appearance or those dissatisfied with their hair condition. However, it may not be appropriate for people with skin conditions, skin allergies, keloid tendencies, or for pregnant or breastfeeding women. For example, performing hair removal on someone with folliculitis before the inflammation has healed could worsen the condition.
- Hair Growth Treatment: Applicable for individuals experiencing hair loss due to various causes, such as androgenetic alopecia or alopecia areata. However, hair issues caused by congenital absence of hair follicles may not respond to standard hair growth treatments. Additionally, individuals allergic to hair growth medications should avoid using them.
Select Equipment
Hair Removal Equipment: Common hair removal devices currently available on the market include laser hair removal devices and IPL (Intense Pulsed Light) hair removal devices. Laser hair removal devices concentrate energy with strong targeting, delivering better results for dark hair, such as emerald laser hair removal devices and semiconductor laser hair removal devices. IPL hair removal devices have more dispersed energy and a broader range of applications, capable of treating hair of different colors and thicknesses simultaneously, such as IPL photon hair removal devices. When selecting a device, consider parameters like wavelength, energy density, and pulse width, as well as the device's safety and stability.
Hair Growth Equipment: Low-level laser hair growth caps are a common type of hair growth device. They stimulate hair follicles using laser light at specific wavelengths to promote hair growth. When choosing one, pay attention to whether the laser wavelength falls within the effective range of 650–670 nm, and consider the laser's output power and distribution uniformity.

Hair Removal Pricing
Hair removal prices vary depending on the area, equipment, and number of sessions. Generally, single sessions for small areas (such as the upper lip or bikini line) cost approximately 1,000–2,500 KRW, with full treatment courses ranging from 4,000–10,000 KRW. For larger areas (such as legs or back), single sessions cost around 2,000–4,000 KRW, and full treatment courses range from 10,000–20,000 KRW. If premium imported equipment is selected, prices may be higher.
Hair Growth Treatment Pricing
Hair growth medications such as minoxidil cost between 200–800 KRW per bottle (60ml–100ml), with the total expense depending on the duration of use due to the extended treatment cycle. Low-level laser hair growth caps vary significantly in price, ranging from 50,000 to several hundred thousand KRW, with differences in functionality and quality.
Hair Removal
After completing hair removal treatment, a significant reduction in hair quantity, a marked slowdown in growth rate, and a transformation of hair to a finer, softer texture are expected. However, it is important to recognize that even after multiple sessions, completely preventing hair regrowth is difficult, and some fine residual hairs may remain. Results may vary among individuals, depending on personal hair characteristics, treatment adherence, and other factors.
Hair Growth
Following hair growth treatment, hair loss is expected to be controlled, with hair gradually becoming thicker and density increasing. However, for patients with severe hair loss, full restoration to a completely normal hair state may not be achievable, though cosmetic appearance can be improved to a certain extent.
Combination Therapy
Hair Removal: Laser hair removal can be combined with intense pulsed light (IPL) hair removal. First, use IPL to preliminarily treat large areas of hair, reducing hair quantity and thickness, followed by laser hair removal for precise treatment of remaining coarse and hard hairs, thereby improving the effectiveness and efficiency of hair removal.
Hair Regrowth: For patients with androgenetic alopecia, topical minoxidil can be combined with oral finasteride. Minoxidil promotes hair growth, while finasteride inhibits the effect of androgens on hair follicles. The synergistic action of both agents more effectively controls hair loss and stimulates regrowth. Additionally, low-level laser hair regrowth caps can be used as adjunctive therapy to enhance treatment outcomes.
Side Effects and Complications
Hair Removal: After laser or intense pulsed light (IPL) hair removal, the skin may exhibit transient erythema, edema, and pain, which typically resolve spontaneously within a few hours to several days. A minority of individuals may experience hyperpigmentation or hypopigmentation, which generally gradually recovers within 3 to 6 months. If the procedure is performed improperly, it may also lead to serious complications such as blistering and scarring.
Hair Regrowth: Minoxidil use may cause mild scalp itching, redness, and scaling as adverse reactions. A small number of individuals may experience systemic adverse effects such as increased heart rate and blood pressure changes, though these are rare. Finasteride may cause side effects like decreased libido and erectile dysfunction, but the incidence is relatively low, and most cases resolve after discontinuation of the medication.
Hair Removal Side Effects: In addition to the skin redness, edema, and hyperpigmentation mentioned above, perifollicular edema and skin dryness may also occur. After hair removal, failure to practice sun protection can increase the risk of hyperpigmentation.
Hair Regrowth Side Effects: Apart from the inherent side effects of the medication, long-term use of hair regrowth drugs may lead to a certain degree of drug resistance, resulting in reduced efficacy. Furthermore, sudden discontinuation of treatment may trigger rebound hair loss, where hair loss worsens in the short term after stopping the medication.
Selecting Devices
Hair Removal Devices: When choosing, consider parameters such as wavelength, energy density, and pulse width. For example, semiconductor laser hair removal devices typically operate at a wavelength of 800–810 nm, offering high selectivity for melanin to effectively destroy hair follicles. IPL (Intense Pulsed Light) hair removal devices have a broader wavelength range (500–1200 nm) and can target hair of varying colors and thicknesses simultaneously. It is also important to evaluate the device's cooling system; an effective cooling mechanism minimizes thermal damage to the skin and enhances treatment comfort.
Hair Growth Devices: For low-level laser hair growth caps, select products with stable laser output power and wavelengths within the effective range (650–670 nm). Additionally, consider the device's comfort during wear and ease of use, such as its portability and whether it offers adjustable settings.
Contraindications for Procedures
Hair Removal: Hair removal treatments are contraindicated for individuals with skin damage, infection, or inflammation. Patients with severe systemic conditions such as heart disease, hypertension, or diabetes are not suitable candidates. Additionally, those taking photosensitive medications should avoid hair removal, as these drugs may increase skin sensitivity to light, potentially exacerbating adverse reactions.
Hair Growth: Minoxidil or finasteride are contraindicated for individuals with known allergies to these hair growth medications. Finasteride is prohibited for use during pregnancy and breastfeeding due to potential harmful effects on the fetus.

Side effects of hair growth: Beyond the inherent side effects of the medication, long-term use of hair growth drugs may lead to drug resistance, resulting in reduced efficacy. Additionally, abrupt discontinuation can trigger rebound hair loss, where hair loss worsens significantly shortly after stopping treatment.
Self-Diagnosis of Symptoms
Hair Loss: If more than 100 hairs are shed daily for over 2–3 months, or if you notice gradual thinning and softening of hair, receding hairline, or widening part lines, you may be experiencing hair loss. You can also perform a pull test for self-assessment: gently grasp 50–60 strands of hair with your fingers and pull lightly. If more than six hairs come out each time, it may indicate a risk of hair loss.
Hirsutism: If women exhibit abnormal increase and thickening of hair on the face, chest, abdomen, and other areas, resembling male hair distribution patterns, this could be a sign of hirsutism. It is also important to check for accompanying symptoms such as irregular menstruation, obesity, or acne, as these may be linked to hormonal imbalances.
Select Treatment Plan
Hair Loss Treatment Plan: For androgenetic alopecia, a pharmacological approach using topical minoxidil and oral finasteride (for men), combined with low-level laser therapy caps for adjunctive treatment, is recommended. For patients with alopecia areata, mild cases can be treated with topical corticosteroids and minoxidil, while severe cases may require oral corticosteroids or immunosuppressants.
Hair Removal Treatment Plan: For large areas with dense hair, multiple sessions of laser or intense pulsed light (IPL) hair removal are recommended. For small areas such as the upper lip or chin, permanent methods like electrolysis can be chosen, although electrolysis is relatively complex to perform and requires longer treatment duration.
