The treatment principle
How Does Laser Hair Removal Work?
Hair-reduction systems deliver controlled light energy towards suitable pigment within the hair. That energy is converted into heat and can damage structures responsible for producing future growth while the practitioner protects the surrounding skin.
The target is not simply the hair visible above the skin. Treatment depends on the relationship between the hair, its follicle, the surrounding skin and the stage of growth at the time of the appointment.
The most accurate promise is long-term hair reduction. A course may greatly reduce density, thickness and growth speed, but it cannot guarantee that every hair will disappear forever.
1
Suitable Pigment Absorbs Light
Dark, coarse hairs generally provide a stronger target than pale, fine hairs.
2
Energy Becomes Heat
Controlled heating affects the follicle while skin cooling and technique support comfort and safety.
3
Growth Is Reduced
Successfully treated follicles may produce less hair, finer hair or no visible regrowth for a prolonged period.
4
Other Cycles Are Treated Later
Appointments repeat because only a proportion of follicles are at a responsive stage at one time.
Thickness
Coarse terminal hair often responds more predictably than very fine or downy growth.
Growth Cycle
Different follicles enter active growth at different times.
Hormones
Hormonal stimulation may drive new growth and increase maintenance needs.
Assessment comes before treatment
Who May Be Suitable for Laser Hair Removal?
Suitability is not decided by one photograph or skin-type number. Pulsar reviews your natural skin tone, recent tanning, hair colour and thickness, treatment area, medical history, medication, previous reactions and goals.
Dark, Coarse Hair
Black and dark brown terminal hairs usually provide the clearest target, although response still varies by area and growth stage.
Darker Skin Tones
Many darker skin tones can be treated, but technology, settings, technique and recent tanning require careful consideration.
Hormonal Growth
PCOS, menopause, medication and other hormonal influences may mean additional sessions or longer-term maintenance.
Pale, Red, Grey or White Hair
White, grey, very pale blonde and many red hairs may contain too little suitable melanin to respond effectively.
Fine or Downy Hair
Very fine facial or body hair may be a weak target. Treating unsuitable fine hair can carry a recognised risk of stimulated growth.
Tanned or Irritated Skin
Recent tanning, sunburn, fake tan, active infection, open skin or significant irritation may make treatment unsuitable that day.
New or rapidly changing hair growth may need medical assessment
Cosmetic treatment does not diagnose the cause of excess hair. Sudden growth, other hormonal symptoms or an unexplained change should be discussed with an appropriate healthcare professional.
Choose the correct Pulsar clinic
Advanced Diode in Chorley or IPL Hair Reduction in Horwich?
Laser and intense pulsed light are both used for hair reduction, but they are different technologies. We recommend the appropriate clinic only after considering your treatment area and individual suitability.
Advanced Diode Laser Hair Removal
Our principal pathway for face, body, intimate, grooming, full-body and full-scalp treatment.
- Professional diode laser technology
- Men’s and women’s treatment pathways
- Specialist full-scalp option
- Defined multi-area quotations
- Consultation and patch testing
IPL Hair Reduction
Consultation-led intense pulsed light hair reduction for suitable clients and agreed facial or body areas.
- Broad-spectrum intense pulsed light
- Suitability assessed before booking
- Selected facial and body areas
- Individual skin and hair assessment
- Patch testing before treatment
IPL is not a laser. Both can reduce suitable hair, but they deliver light differently. Device type is only one factor; hair, skin, settings, technique, cooling, timing and clinical judgement also influence the outcome.
Courses follow biology, not a fixed guarantee
How Many Sessions Will You Need?
Pulsar’s advertised courses contain six sessions. That is a treatment plan—not a promise that every client or every area will be complete after the sixth appointment.
Why Six Is a Starting Course
A structured course gives the practitioner repeated opportunities to reach different groups of actively growing hairs and review the pattern of response.
Why Intervals Change
Facial hair and body hair do not share identical growth cycles. Intervals may lengthen as regrowth becomes slower and less dense.
Why Maintenance Exists
Remaining follicles and new hormonally activated growth may appear later. Maintenance is scheduled from visible regrowth, not automatically promised away.
Personalised course planningExplore the Six Factors That Shape Your CourseHair, treatment area, hormones, previous removal and attendance can all affect session numbers and timing.6 factors
Your treatment course
What Influences the Number and Timing of Your Sessions?
These six connected factors help explain why one client’s course may differ from another. For each factor, we show why it matters and what Pulsar reviews when planning your appointments.
| Factor | How it may affect the course | What Pulsar reviews |
|---|---|---|
| Hair colour | Darker hair usually gives a stronger target; pale hair may respond weakly. | Visible colour and likely pigment content. |
| Hair thickness | Coarse hair often responds better than fine or downy hair. | Density, diameter and whether the hair is suitable to treat. |
| Treatment area | Face, body, intimate areas and scalp can respond at different rates. | Area-specific growth pattern and interval. |
| Hormones | PCOS, menopause and other influences can drive continued growth. | History, pattern and realistic maintenance expectations. |
| Previous removal | Waxing or plucking can temporarily remove the target and disrupt timing. | When root-removal methods stopped. |
| Attendance | Appointments that are too early, too late or frequently missed may reduce course efficiency. | Visible regrowth and response before scheduling. |

Your first stage
What Happens at the Consultation and Patch Test?
A consultation is not a sales formality. It is where we decide whether the hair and skin are suitable, identify reasons to postpone or modify treatment and agree exactly what will be treated.
- Skin tone and recent tanning history
- Hair colour, thickness, density and growth pattern
- Medical history, medication and recent procedures
- Hormonal influences and previous hair-removal methods
- Treatment boundaries, goals, costs and likely maintenance
- Patch-test response and individual precautions
1
Assess
We examine the skin, hair and treatment area and discuss relevant history.
2
Agree
The exact area, boundaries, technology, price and expected course are confirmed.
3
Patch Test
A small area is tested where required to observe comfort and skin response.
4
Plan
Full treatment proceeds only when the area remains suitable and the required interval has passed.
Protect the target and the skin
How to Prepare for Laser Hair Removal
Your appointment instructions may be adjusted to your technology, area and skin. Follow the specific preparation given by Pulsar even where generic online advice differs.
Do
- Shave using the timing provided by the clinic.
- Keep exposed skin protected from tanning and sunburn.
- Tell us about new medicines, illness or skin changes.
- Arrive with the treatment area clean and product-free when requested.
- Tell us if the area has recently reacted to another procedure.
- Confirm boundaries before shaving an intimate or specialist area.
Don’t
- Do not wax, pluck, thread or epilate.
- Do not attend with sunburn, a fresh tan or fake tan.
- Do not bleach the hair before assessment.
- Do not apply fragranced products immediately before treatment.
- Do not hide medication or photosensitivity information.
- Do not treat over open, infected or significantly irritated skin.
Why shaving is different from waxing: shaving removes hair above the skin but leaves the follicle target in place. Waxing, plucking, threading and epilating pull the target from the follicle and should be avoided throughout the course.
What treatment may feel and look like
What Happens During and After an Appointment?
From assessment to regrowth reviewFollow Your Appointment JourneySee what happens before treatment, during light delivery, immediately afterwards and through the shedding phase.6 stages
Before Treatment
The area and health information are reviewed. Skin suitability, regrowth and any changes since your last appointment are checked.
Eye Protection
Appropriate protective eyewear is used. Only authorised people should be present in the controlled treatment area.
Light Delivery
The practitioner treats the agreed area using settings and technique selected for your skin, hair and response. Sensation may include warmth, tingling or brief snapping.
Immediate Response
Temporary redness, warmth and small raised bumps around follicles can occur. The skin response is reviewed before you leave.
Shedding Phase
Treated hairs may appear to grow before loosening and shedding. This is not necessarily new growth and should not be plucked.
Regrowth Review
New groups of hair gradually appear. The next appointment is based on actual recovery and growth pattern rather than the calendar alone.
Keep recently treated skin calm
Laser Hair Removal Aftercare
Follow the individual advice given at your appointment. The aim is to reduce avoidable heat, friction, irritation and ultraviolet exposure while the skin settles.
Keep Skin Cool
Avoid excessive heat and use gentle cooling only as advised. Never place frozen material directly on skin.
Avoid Friction
Use loose clothing and avoid rubbing, scratching or aggressive exfoliation while the area feels sensitive.
Avoid Tanning
Protect exposed treatment areas from sunlight and do not use sunbeds or tanning products during the course.
Shave, Don’t Pluck
Shaving is normally permitted once comfortable. Do not wax, thread, pluck or epilate.
Keep Skincare Simple
Avoid fragranced, active or irritating products for the period advised for your area and response.
Report Concerns
Contact Pulsar for worsening pain, blistering, marked swelling, spreading redness, discharge or delayed healing.
Judge progress over the course
What Do Realistic Results Look Like?
Signs of Progress
- Slower visible regrowth
- Patchier distribution
- Reduced density
- Finer or softer remaining hair
- Longer gaps between shaving
- Less repeated shaving irritation for some clients
What Results Do Not Guarantee
- Removal of every follicle
- An identical response across every body area
- No future hormonally activated growth
- Success on white, grey or pigment-poor hair
- Completion in exactly six appointments
- No need for future maintenance
More energy does not automatically mean a better result
Settings must remain appropriate for the skin, hair and response. Chasing stronger reactions can increase the risk of burns, blistering and pigment change without creating a better long-term outcome.

Risks, Side Effects and Reasons to Postpone
Common Temporary Reactions
Warmth, redness, tenderness and follicular swelling may occur and usually settle over hours or days.
Less Common Complications
Blistering, crusting, infection, burns, prolonged sensitivity, scarring and temporary or lasting pigment change are recognised risks.
Paradoxical Hair Growth
Rarely, increased or stimulated growth can occur, particularly where fine or hormonally influenced hair is treated.
Treatment May Be Postponed When:
- The skin is recently tanned or sunburned.
- Fake tan remains on the area.
- There is open, infected or inflamed skin.
- A medication or health change requires review.
- The previous reaction has not fully settled.
- The hair has been removed from the root.
Contact Pulsar When:
- Pain, heat or redness is worsening rather than settling.
- Blistering or crusting develops.
- There is discharge, spreading redness or delayed healing.
- You notice unexpected pigment or texture change.
- You are unsure whether a product or activity is safe.
- Your health or medication changes during the course.
After the initial course
Why Might Maintenance Be Needed?
Long-term reduction does not stop every future follicle from becoming active. Maintenance is most useful when there is enough suitable visible regrowth to justify another treatment.
Incomplete Response
Some follicles may not be disabled during the initial course or may produce finer regrowth later.
Hormonal Change
PCOS, menopause, pregnancy-related change, medication or ageing can influence new visible growth.
Face vs Body
Hormone-sensitive facial areas often need a different long-term plan from more stable body areas.
Maintenance should follow regrowth. It is not automatically booked at a fixed interval when there is insufficient suitable hair to target.
Frequently asked questions
Complete Laser Hair Removal FAQs
Is laser hair removal permanent?
It is best described as long-term hair reduction. A successful course can substantially reduce the amount, thickness and speed of regrowth, but remaining follicles, hormonal changes and newly activated growth can mean that maintenance is required.
How many laser hair removal sessions will I need?
Pulsar’s advertised courses contain six sessions, but the total needed varies with the treatment area, hair colour and thickness, growth cycle, hormones, previous methods and individual response. Some clients need additional sessions or maintenance.
Why are several sessions needed?
Hair follicles are not all in the same growth stage at once. Treatment is most effective on suitable hairs in an active growth stage, so appointments are repeated to reach different groups of follicles over time.
Which hair colours respond best?
Dark brown and black hairs usually provide the strongest melanin target. White, grey, very pale blonde and many red hairs contain too little suitable pigment and may respond poorly or not at all.
Can darker skin tones have laser hair removal?
Many darker skin tones can be treated, but suitability, technology, settings and technique must be selected carefully. Pulsar assesses skin tone, recent tanning, hair characteristics and individual risk before treatment.
Should I shave before laser hair removal?
Usually yes, using the timing given by the clinic. Do not wax, pluck, thread or epilate because these methods remove the follicle target needed for treatment.
What happens to the hair after treatment?
Treated hairs do not always disappear immediately. They may look as though they are growing before loosening and shedding naturally over the following days or weeks. Do not pluck them out.
Does laser hair removal hurt?
Sensation varies by area, density and individual sensitivity. Many clients describe warmth, tingling or a brief snapping feeling. The practitioner monitors comfort and skin response throughout treatment.
Can laser hair removal help ingrown hairs?
Reducing suitable hair growth may reduce repeated shaving irritation, razor bumps and ingrown hairs, although results vary and active infection or severely inflamed skin may need assessment before cosmetic treatment.
Can I have laser hair removal with PCOS or hormonal hair growth?
Many clients with hormonally influenced growth have treatment, but the face and other hormone-sensitive areas may need more sessions and ongoing maintenance. New or unexplained hair growth may also warrant medical assessment.
What is the difference between laser and IPL hair reduction at Pulsar?
Pulsar Chorley provides advanced diode laser hair removal. Pulsar Horwich provides IPL hair reduction for suitable clients. Both require consultation-led assessment, but they use different light-delivery technologies and are not interchangeable labels.
What are the common reactions after treatment?
Temporary warmth, redness, sensitivity and small raised bumps around follicles can occur. Less common risks include blistering, crusting, infection, scarring, pigment change and paradoxical increased hair growth.
Can I tan during a laser hair removal course?
Deliberate tanning, sunbeds, sunburn and fake tan should be avoided according to the clinic’s instructions. A recent tan can change skin risk and may require treatment to be postponed.
Will I need maintenance treatments?
Some clients need occasional maintenance when remaining or newly activated hair becomes visible. Maintenance is more common where growth is hormonally influenced, and its timing depends on actual regrowth rather than a fixed promise.
