Laser Hair Removal
A Medical Approach to Long-Term Hair Reduction
Laser hair removal is a light-based procedure designed to reduce unwanted hair growth by directing controlled laser energy toward pigment within the hair follicle.
Because hair growth, skin tone, hair colour and treatment response vary between individuals, an appropriate treatment plan should be based on assessment rather than a fixed number of sessions for everyone.
At Aesthe Clinic Samut Songkhram, treatment settings and treatment intervals are considered according to the area being treated, skin characteristics and individual hair-growth patterns.

LASER HAIR REMOVAL
How Laser Hair Removal Works
Laser energy is absorbed by pigment in the hair and transferred toward the hair follicle. This process can reduce the follicle's ability to produce new hair.
Hair grows in different phases, and laser treatment is most effective when hairs are in an appropriate active growth phase. As not all hairs are in the same phase at the same time, a course of several treatment sessions is usually required.
Over time, treated areas may show:
- Reduced hair density
- Slower hair regrowth
- Finer or less noticeable regrowth
- Reduced need for frequent shaving or other temporary hair-removal methods
The degree of improvement varies between individuals.

Why Assessment Matters
Several factors can influence laser hair reduction, including:
- Skin tone
- Hair colour
- Hair thickness
- Hair density
- Treatment area
- Hormonal influences
- Previous hair-removal methods
- Previous laser treatment
- Certain medicines or medical conditions
Before treatment, the skin and hair characteristics should be assessed so that appropriate treatment parameters can be considered.
People with unusually rapid or increased hair growth may also require assessment for possible underlying factors where clinically appropriate.
Treatment Areas
Laser hair reduction may be considered for various areas of the face and body, depending on individual suitability.
Common areas include:
- Upper lip
- Chin
- Jawline
- Underarms
- Arms
- Legs
- Chest
- Abdomen
- Back
- Bikini area
Who May Be Suitable?
Laser hair removal may be considered for individuals who would like to reduce unwanted hair growth and prefer a longer-term approach compared with temporary methods such as shaving or waxing.
Treatment response can vary depending on the amount of pigment within the hair.
Hair that contains little pigment may respond differently from darker hair, and the physician or treatment provider should explain whether laser treatment is likely to be appropriate.
When Treatment May Need to Be Postponed
Laser treatment may need to be delayed or reconsidered when certain conditions are present, such as:
- Active infection or significant inflammation in the treatment area
- Open wounds
- Recent significant sun exposure or tanning
- Certain photosensitising medicines
- Previous unexpected reactions to laser treatment
- Medical conditions that may affect treatment suitability
Patients should disclose relevant medicines, medical conditions and previous procedures before treatment.

What Results Can Be Expected?
The goal of treatment is progressive reduction in unwanted hair growth, rather than guaranteeing complete or permanent removal of every hair.
As treatment progresses, some patients may notice that regrowth becomes less dense, slower or finer.
Individual responses differ, and additional or maintenance sessions may sometimes be considered over time.
Hormonal and biological factors can also influence future hair growth.
Aftercare
Following treatment, temporary redness, warmth or mild sensitivity may occur around the treated follicles.
Patients should follow the aftercare instructions provided by the clinic.
Depending on the treatment area and individual skin response, recommendations may include:
- Avoiding unnecessary heat or irritation immediately after treatment
- Using appropriate gentle skin care
- Protecting exposed skin from excessive sun exposure
- Avoiding picking, scratching or aggressive exfoliation
- Following instructions regarding shaving between sessions
Contact the clinic if an unexpected or persistent reaction develops.
Risks & Limitations
Laser hair removal is a medical-device-based procedure and is not completely risk-free.
Possible effects may include:
- Temporary redness
- Swelling around hair follicles
- Skin sensitivity
- Temporary discomfort
- Pigment changes
- Blistering or superficial skin injury in uncommon circumstances
The risk profile may vary according to skin characteristics, laser parameters, treatment area and other individual factors.
Appropriate assessment, parameter selection and aftercare are therefore important parts of treatment planning.
