Laser Hair Removal vs Waxing, Shaving, Epilators and Creams
Medical Director Dr Sin Yong compares laser hair removal with waxing, shaving, epilators and creams: how long each lasts, skin problems, and how to combine them.
WhatsApp to Enquire →Key facts ↓Laser hair removal vs waxing: waxing pulls hair out for a few weeks and is repeated for life, while a laser course reduces the follicles that grow dark hair. Shave during a course. See laser hair removal in Singapore.
- Laser outperforms waxing and shaving: a review of controlled trials found laser superior to shaving, waxing and electrolysis in the short term; no method removed every hair for good [1].
- Trial evidence: a Cochrane review of 11 trials in 444 people found about 50 in 100 short-term hair reduction with alexandrite and diode lasers [2].
- A course, not one visit: in 144 Asian patients, reduction rose from about 32 in 100 after one treatment to 55 in 100 after three [3].
- Razor bumps: in 40 men with razor bumps, long-pulsed Nd:YAG plus a topical cream improved bumps and hair density more than either alone [4].
- Darker skin: conservative energy over several sessions improves safety in darker skin types [5].
How does laser hair removal compare with waxing and shaving?
Shaving, waxing, epilators and creams remove hair for days or weeks and are repeated for life; laser reduces the follicles that grow it, over a course of sessions.
Each method has a place, and many people use more than one. During a laser course you can keep shaving, but waxing, epilating and plucking pause, because the laser needs the root in place. Laser at IN Eternity Clinic uses the Lutronic Clarity II, with 755 nm or 1064 nm chosen for your skin and settings varied for coarse, medium and fine hair.
| Method | What it removes | Hair back in | Common skin issues | During a laser course |
|---|---|---|---|---|
| Shaving | Hair at the skin surface | 1 to 3 days | Razor bumps, nicks, ingrown hairs | Yes: shave the day before a session |
| Waxing or sugaring | Hair with its root | About 3 to 6 weeks | Redness, bumps, ingrown hairs, occasional burns or marks | No: stop about four weeks before |
| Epilator | Hair with its root | About 3 to 4 weeks | Discomfort, bumps, ingrown hairs | No: same as waxing |
| Hair removal cream | Hair dissolved at the surface | A few days | Irritation or chemical burns in sensitive skin | Avoid on the treated area around sessions |
| Threading or plucking | Single hairs with the root | About 2 to 6 weeks | Redness, ingrown hairs | No: shave or trim instead |
| Laser hair removal | Reduces follicles that grow dark hair | Long-term reduction over a course | Short-lived redness and bumps | The course itself |
Is laser hair removal more effective than waxing?
Yes, for dark hair: trials found laser superior to shaving and waxing in the short term, and a course gives lasting partial reduction, which waxing does not.
An evidence review of controlled trials found laser hair reduction better than shaving, waxing and electrolysis in the short term, improving with repeated treatment, while no method removed every hair for good [1]. A Cochrane review of 11 trials found about 50 in 100 short-term hair reduction with alexandrite and diode lasers [2]. In 144 Asian patients, reduction rose from about 32 in 100 after one alexandrite treatment to 55 in 100 after three [3], which is why laser is a course rather than a single visit.
Can you wax before or during laser hair removal?
No. Stop waxing, epilating, threading and plucking about four weeks before your first session and throughout the course; shaving is fine.
Laser light is absorbed by the pigmented hair inside the follicle. Waxing pulls that hair out, leaving nothing for the laser to heat until it regrows. Shaving cuts the hair at the surface and leaves the root in place, which is exactly what the laser needs. Shave the day before each session, so no long hair sits on the skin to heat and sting. Full preparation and aftercare are in laser hair removal aftercare.
Which is better for ingrown hairs and razor bumps?
Laser usually helps most: fewer and finer hairs mean fewer hairs curling back into the skin, whereas shaving and waxing keep causing them.
Razor bumps (pseudofolliculitis) are common on the beard line, neck, bikini line and underarms, especially with coarse, curly hair. In 40 men with razor bumps, a long-pulsed Nd:YAG laser course combined with a topical cream improved bumps and hair density more than either alone [4]. Darker skin types with these conditions can be treated with laser, with conservative energy [5]. See ingrown hairs and razor bumps and laser hair removal for men.
Does shaving make hair grow back thicker?
No. Shaving cuts the hair at the surface and does not change the follicle; regrowth only feels coarser because the cut tip is blunt.
Waxing and plucking do not destroy the follicle either; the hair simply takes longer to return. Laser is the only one of these that targets the follicle itself. Shaving between laser sessions is encouraged, because it keeps the hair short without disturbing the root.
“Waxing removes the hair; laser treats the follicle that grows it. We use two wavelengths, 755 nm and 1064 nm, with settings varied for coarse, medium and fine hair and for your skin type.”
Which is gentler for sensitive or darker skin?
It depends on the reaction your skin has had: waxing and creams irritate some people, while laser in darker skin needs 1064 nm and conservative energy.
Any repeated irritation, from hot wax, a chemical cream or a too-strong laser, can leave brown marks, and darker skin is more prone to them [7]. With laser, 1064 nm Nd:YAG is the preferred wavelength for pigmented skin [6]. Hair removal creams work by dissolving hair, so test a small patch first and keep them off broken or freshly lasered skin. See darker skin tones.
Is laser hair removal worth it compared with waxing?
For many people it is, because waxing and shaving are repeated for life, while a laser course reduces how much there is to remove.
Laser is an upfront course, usually about six to eight sessions per area, sometimes with maintenance; waxing is a smaller cost repeated every few weeks. Laser is not the right choice for white, grey, red or very fair hair, which does not respond; in that case waxing or shaving remain sensible. What sets the total for laser is explained in laser hair removal cost. At IN Eternity Clinic a consultation fee applies, and it is waived if you go ahead with any medical treatment; the fee is S$120.
What about at-home laser and IPL devices?
They use lower energy than clinic lasers, suit mainly light skin with dark hair, and have less research behind them.
A review of hair removal technologies noted that more research is needed on home-use devices [6]. They carry no skin check, so tanned or darker skin is at greater risk. A comparison of light sources is in IPL vs laser hair removal vs SHR.
What Dr Sin Yong looks for
- How you remove hair now, and when you last waxed, epilated or plucked the area.
- Ingrown hairs, razor bumps or dark marks from shaving or waxing.
- Your skin type and any recent tan, which decide 755 nm or 1064 nm.
- Whether the hair is coarse, medium or fine, and dark enough for laser.
- Reactions to creams or wax, which can point to sensitive skin.

Frequently asked questions
Is laser hair removal better than waxing?
For dark hair, laser gives long-term reduction while waxing lasts a few weeks. Waxing remains a sensible option for hair laser cannot treat, such as white, grey or very fair hair.
How long before laser should I stop waxing?
Usually about four weeks before your first session, and then throughout the course. Shaving is fine, and you should shave the day before each session.
Can I shave between laser hair removal sessions?
Yes. Shaving leaves the root in place, which the laser needs, and does not make hair thicker.
Can I use hair removal cream during a laser course?
It is better avoided on the treated area around sessions, because it can irritate the skin. Shaving is the simpler choice during a course.
Does laser help ingrown hairs better than waxing?
Usually yes: fewer and finer hairs mean fewer ingrown hairs, while waxing and shaving keep causing them. Inflamed bumps are calmed before laser.
Can I go back to waxing after a laser course?
Yes, for any hair the laser could not reach, such as fine light hairs. Most people find there is far less to remove.
Is laser hair removal worth it compared with waxing?
For many people, yes, because waxing is repeated for life. At IN Eternity Clinic a S$120 consultation fee applies and is waived if you go ahead with any medical treatment.
